Full Moon Party Koh Phangan: The Honest Backpacker's Guide (2026)

I've been to three Full Moon Parties. The first one was incredible -- I danced until sunrise, made friends from six countries, and watched fire dancers spin through the dark while 20,000 people lost their minds on a beach in the Gulf of Thailand. The second one was fine. The third one I left at 1 AM because I'd seen it all before and my feet hurt.

That tells you everything about the Full Moon Party: it's an experience worth having exactly once. Maybe twice if you're with the right people. But you need to walk in with your eyes open, because the gap between the Instagram version and the reality is wide -- and the safety risks are real.

This is the guide I wish I'd had before my first one. No hype, no scare tactics. Just what it actually is, what it actually costs, and how to come home in one piece.

What the Full Moon Party Actually Is

Strip away the mythology and here's what you're looking at: every full moon, somewhere between 10,000 and 30,000 people cram onto Haad Rin Nok (Sunrise Beach) on the southeastern tip of Koh Phangan island. The beach is about 700 meters long. Bars line the sand, each blasting different music -- EDM from one, reggae from the next, drum and bass from the one after that. Neon paint stations glow under blacklights. Fire dancers perform on the sand. Drinks are served in children's sand buckets. The party starts around 9 PM and runs until the sun comes up.

It started in the late 1980s as a goodbye party for about 30 backpackers. By the mid-90s it was drawing thousands. Today it's a commercial operation -- slick, organized, and very much a business. But the energy is still genuine. When you're standing on that beach at midnight, paint on your arms, bass rattling your chest, moon hanging fat over the water, it doesn't matter that it's commercial. It hits different.

The beach has distinct zones:

| Section | Vibe | Music | |---------|------|-------| | South end (Cactus Bar area) | Reggae, chill, fire shows | Reggae, dancehall | | Center (Drop In Bar, Mellow Mountain) | Main party zone, biggest crowds | EDM, house, pop remixes | | North end (Zoom Bar area) | Intense, younger crowd | Drum and bass, hardstyle, trance | | The hill (Mellow Mountain / Rock) | Elevated views, slightly less packed | Mixed, lounge |

My advice: spend the first hour walking the entire beach to find your zone. The south end is the best place to watch fire shows. The center is where the energy peaks. The north end is where the music gets heavier and the crowd gets younger. Mellow Mountain gives you a view of the whole thing from above -- climb up at some point during the night.

2026 Full Moon Party Dates

The party falls on every full moon, though dates occasionally shift by a day or two to avoid Buddhist holidays (Makha Bucha, Visakha Bucha).

| Month | Full Moon Date | Party Date (Estimated) | |-------|---------------|----------------------| | January | January 13 | January 13 | | February | February 12 | February 12 | | March | March 14 | March 14 | | April | April 12 | April 12 | | May | May 12 | May 12 | | June | June 11 | June 11 | | July | July 10 | July 10 | | August | August 8 | August 8 | | September | September 7 | September 7 | | October | October 7 | October 7 | | November | November 5 | November 5 | | December | December 4 | December 4 |

Peak months are December, January, and August, when crowds hit 20,000-30,000+. Low season (June-September) draws 5,000-10,000 -- still a proper party, just with more room to breathe. During peak season, there are sometimes two Full Moon Parties in a single month.

Exact dates get confirmed about two weeks before. Check locally when you arrive on the island.

Getting to Koh Phangan

From Bangkok

You have three realistic options:

Option 1: Combined bus + ferry (cheapest) Book a combined ticket from Bangkok to Koh Phangan. One ticket covers the overnight bus from Bangkok's Khao San Road area or bus terminal to Surat Thani province, the transfer to Donsak Pier, and the ferry to Thong Sala pier on Koh Phangan. Total journey: 13-15 hours. Cost: 750-1,200 THB (US$21-34). Operators: Lomprayah, Seatran Discovery.

Option 2: Flight + ferry (fastest) Fly Bangkok to Surat Thani (1.5 hours, 1,000-2,500 THB / US$28-70 on AirAsia or Nok Air), then ferry from Donsak Pier to Thong Sala (2 hours, 650-700 THB / US$18-20). Total: about 5 hours including transfers.

Option 3: Flight to Koh Samui + ferry Bangkok Airways flies direct to Koh Samui (1 hour) but tickets run 2,500-5,000 THB (US$70-140) because Bangkok Airways has a monopoly on the route. Then ferry Samui to Phangan (30-45 minutes, 150-400 THB / US$4-11). Faster but significantly more expensive.

From Koh Samui

This is the most common approach -- many travelers are already on Samui.

| Ferry | Route | Duration | Price | Notes | |-------|-------|----------|-------|-------| | Haad Rin Queen | Big Buddha Pier to Haad Rin | 45 min | 200-350 THB (US$6-10) | Special late ferries on party night until 11 PM-midnight | | Lomprayah | Samui to Thong Sala | 30 min | 400 THB (US$11) | Regular schedule | | Raja Ferry | Samui to Thong Sala | 45 min | 150 THB (US$4) | Cheapest, rarely sells out |

The Haad Rin Queen is your best bet for party night -- it runs special late departures from Big Buddha Pier on Koh Samui and drops you directly at Haad Rin beach. Return ferries run early morning (5-7 AM) back to Samui.

From Surat Thani (Mainland)

Lomprayah catamaran from Donsak Pier: 2 hours, 700 THB (US$20)
Raja Ferry from Donsak Pier: 2.5 hours, 250 THB (US$7)
Night boat from Ban Don Pier: departs 11 PM, arrives 5 AM, 400 THB deck / 600 THB cabin (US$11-17)

Where to Stay (and How Much You'll Actually Pay)

Book Early -- This Is Not Optional

Accommodation in Haad Rin on Full Moon Party nights costs 3-5x the normal rate, and the good budget spots sell out months in advance during high season (December-March, August). Book at least 2-3 weeks ahead minimum. For December/January, book 2-3 months ahead.

Accommodation Prices on Party Night

| Type | Normal Night | Full Moon Night | Notes | |------|-------------|----------------|-------| | Dorm bed (hostel) | 200-500 THB (US$6-14) | 600-1,500 THB (US$17-42) | Best budget option | | Fan bungalow | 400-800 THB (US$11-22) | 1,500-3,000 THB (US$42-84) | Basic but private | | AC room (mid-range) | 800-1,500 THB (US$22-42) | 2,500-5,000 THB (US$70-140) | Comfortable | | Resort/hotel | 1,500-4,000 THB (US$42-112) | 4,000-12,000 THB (US$112-336) | Splurge |

Where to Stay: Three Options

Option A: Stay in Haad Rin (recommended)

Walk to and from the party. No transport risk. Sleep when you want. The trade-off is the inflated prices and the fact that you will not sleep before 7 AM because the bass will rattle your walls.

Budget tip: Stay on Haad Rin Nai (the quieter sunset side of the peninsula). It's a 5-10 minute walk over the hill to the party beach, and prices are noticeably lower than beachfront Haad Rin Nok.

Option B: Stay elsewhere on Koh Phangan

Cheaper accommodation, more options, but you'll need a songthaew (shared pickup truck) to get to and from Haad Rin. Songthaews run all night, costing 100-300 THB per person (more after midnight). They get scarce after 3-4 AM, and the temptation to rent a scooter is real -- resist it.

Option C: Day trip from Koh Samui

Take the Haad Rin Queen ferry over, party, catch the 5-7 AM return ferry. If you miss it, you're stuck with an expensive taxi boat (2,000-5,000 THB / US$56-140) or waiting for the next regular ferry. Transportation adds risk.

My recommendation: If you can afford it, book a dorm in Haad Rin. Walking distance to the party eliminates the single biggest safety risk -- transport accidents.

Safety: The Section That Could Save Your Life

I'm putting this front and center because every month -- every single month -- people get hospitalized at the Full Moon Party. Burns, alcohol poisoning, drug reactions, motorbike accidents, drowning, theft. This is not fearmongering. It's the reality of putting 20,000 drunk people on a dark beach with fire, glass, and ocean.

Drink Safety

Buckets are the Full Moon Party drink. A child's sand bucket filled with Thai whiskey (Sangsom or Hong Thong), a mixer (Red Bull, Coke, or Spy), and ice. They cost 150-350 THB (US$4-10) and look fun and innocent.

They are not innocent. A single bucket contains the equivalent of 5-8 standard drinks. The sweet mixer masks the alcohol. People drink through straws (faster absorption) and casually put away 2-3 buckets thinking they're having cocktails. Then they can't stand.

The serious danger is methanol poisoning. Cheap, counterfeit alcohol containing methanol (wood alcohol) has killed travelers in Southeast Asia. Symptoms: blurred vision, headache far worse than a normal hangover, severe vomiting, confusion. If these appear, get to a hospital immediately -- methanol poisoning is fatal without treatment.

How to handle buckets:

Watch your bucket being made. The spirit must come from a sealed, branded bottle (Sangsom, Hong Thong, Blend 285). If they pour from unlabeled bottles, walk away.
Share with a friend. One bucket is enough for two people.
Set a hard limit before you start. Two buckets is a reasonable maximum for the entire night.
Alternate with water. Buy sealed bottles from 7-Eleven before the party (7-15 THB vs. 40-80 THB on the beach).
Eat a full meal before you start drinking.

Drink spiking is real. Drugs get slipped into drinks at the Full Moon Party -- it happens to men and women alike. Never leave your drink unattended. If you put it down and walk away, get a new one. Don't accept drinks from strangers. If your drink tastes unusual (bitter, salty, metallic), stop immediately. If you suddenly feel much drunker than you should based on what you've consumed, tell a friend and get to safety.

Fire Hazards

Fire dancers, fire limbo, fire jump rope, fire poi. They look incredible. They also burn people every single month.

Fire jump rope is the worst offender. A fuel-soaked flaming rope swings while drunk people try to jump over it. The math is simple: impaired coordination plus a burning rope equals hospital visits.

Rules:

Watch fire shows from at least 3-4 meters back
Do NOT participate in fire jump rope. Just don't.
If you absolutely must jump something, be sober enough to clear it -- which defeats the purpose
Tie long hair back. Hair is flammable.
Watch the ground near fire performers -- spilled fuel on sand can reignite
If burned: cool with clean bottled water (not seawater -- infection risk), cover with clean cloth, go to the medical tent. Do NOT apply toothpaste, butter, or ice.

Theft

The Full Moon Party is a pickpocket's dream. Thousands of drunk people with phones in back pockets, wallets in loose shorts, bags left on the sand.

Before you leave your room:

Lock all valuables in your hostel locker or hotel safe
Bring ONLY: cash (just what you need), phone (in a waterproof pouch around your neck), passport photocopy (NOT the real passport), room key
Put your phone in a waterproof pouch that hangs from your neck. Buy one at any 7-Eleven or shop in Haad Rin for 100-500 THB. This is the single best purchase you'll make.
Don't put your phone down. Not on a table, not on the sand, not in your back pocket. Around your neck or zipped front pocket only.

Swimming at Night

People drown at the Full Moon Party. Not every month, but multiple times per year. There are no lifeguards at night. The water is dark. Rip currents exist along Haad Rin, especially at the southern end. Alcohol impairs your swimming ability and your judgment about your swimming ability.

The rule is simple: do not swim drunk. If you want to cool off, wade in waist-deep with friends. Stay close to shore. If you see rough water or feel a current pulling you, get out. If caught in a rip current, don't fight it -- swim parallel to the shore until you're out of the pull, then swim back in.

Drug Penalties

I'll say this as directly as I can: Thai drug laws will wreck your life.

At every Full Moon Party, people will walk up to you and offer mushroom shakes, MDMA, cocaine, laughing gas balloons. This is as certain as the tide.

What most travelers don't know:

Some dealers are police informants. You buy, walk 50 meters, get arrested. The dealer gets a cut or walks free. This is well-documented.
Some dealers ARE undercover police.
MDMA is a Category 1 narcotic in Thailand -- same classification as methamphetamine. Possession carries 1-10 years in prison.
"Mushroom shakes" could contain anything. Reports of shakes containing methamphetamine, ketamine, or random pharmaceutical compounds are not uncommon.
Thai prisons are overcrowded, hot, and brutal. Foreign prisoners describe conditions among the worst they've experienced.
A drug conviction follows you internationally. It can bar you from entering the US, Canada, Australia, and other countries for life.

Bribing your way out costs 50,000-200,000 THB (US$1,400-5,600) with no guarantee -- and attempting to bribe is itself a crime.

My advice: don't buy drugs at the Full Moon Party. The risk-reward calculus is catastrophically bad. For the full breakdown on what's legal, what's not, and what actually happens when tourists get caught, read our Thailand Drug Laws guide.

Road Accidents

Full Moon Party nights are the deadliest nights on Koh Phangan roads. Drunk tourists on rented scooters, Thai drivers on motorbikes, and overloaded songthaews share narrow, potholed, unlit roads.

Never ride a motorbike to or from the party. Even if you're sober, everyone else on the road is not. Use songthaews (shared trucks) or walk. For more on this, see our Scooter Rental safety guide.

Emergency Numbers

| Service | Number | |---------|--------| | Tourist Police (English, 24/7) | 1155 | | Ambulance | 1669 | | Koh Phangan Hospital (Thong Sala) | 077-377-034 | | Bangkok Hospital Koh Samui (serious cases, boat transfer) | 077-429-500 |

There are first aid tents on Haad Rin beach during the party, staffed by medics who deal with party injuries every month. For cuts, minor burns, and intoxication assessment, go there first. For anything serious -- deep cuts, suspected drink spiking, difficulty breathing, burns larger than your palm -- get to the hospital.

What to Wear and What to Bring

Wear

Old clothes you don't care about. You will be covered in neon paint, bucket drink splashes, sand, and sweat by midnight. Wear white or neon -- it glows under blacklights.
Shoes. Not flip-flops. Not sandals. Old sneakers or cheap canvas shoes. By midnight the beach is carpeted with broken glass. This is the most predictable injury at the Full Moon Party and the easiest to prevent. Buy cheap shoes at a market for 200-300 THB (US$6-8) if you don't want to ruin yours.
Swimwear underneath in case you end up in the water.

Bring

| Item | Why | |------|-----| | Cash: 1,500-2,500 THB (US$42-70) | Drinks, food, entry, transport. ATMs will have long lines | | Waterproof phone pouch | Phone protection + anti-theft. Hangs around your neck | | Phone charged to 100% | Communication, flashlight, photos | | Small power bank | Phone will die. Buy at 7-Eleven for 300-600 THB (US$8-17) | | Passport photocopy | ID if needed. Leave the real passport at the hotel | | Room key | Getting back in | | Hand sanitizer | The toilets are horrifying | | Sealed water bottle | Hydration between drinks. Buy at 7-Eleven, not on the beach |

Leave at the Hotel

Your real passport. Expensive jewelry. Nice clothes. Credit cards (unless in a waterproof pouch). DSLR camera. Anything you'd be upset to lose.

Getting Around Koh Phangan on Party Night

If you're not staying in Haad Rin:

| Transport | Price | Notes | |-----------|-------|-------| | Songthaew (shared truck) | 100-300 THB (US$3-8) per person | Runs all night. Price goes up after midnight. Wave one down on the main road | | Private taxi | 300-800 THB (US$8-22) | Negotiate before getting in | | Motorbike | DO NOT RIDE | Drunk driving is the number one killer on party nights. See safety section |

Songthaews run continuously from Thong Sala and other areas to Haad Rin from about 6 PM through dawn. They get scarce after 3-4 AM but don't stop completely.

Half Moon and Black Moon: The Alternative Parties

The Full Moon Party isn't the only option on Koh Phangan. If you want the party island experience without 30,000 people and broken glass, consider these:

Half Moon Festival

When: Twice monthly (week before and week after Full Moon) Where: Ban Tai, inland jungle venue Crowd: 3,000-5,000 Entry: 600-1,000 THB / US$17-28 (includes shuttle bus) Music: Progressive house, trance, techno -- curated DJ lineups with proper sound systems Vibe: Purpose-built festival venue. UV art installations, jungle dance floor, enclosed with security. Less glass, fewer hazards, better music than the Full Moon Party. Many experienced backpackers prefer this.

Shiva Moon Party

When: During the waning crescent (between Full and New Moon) Where: Haad Yuan (boat access only) Crowd: 500-2,000 Entry: 300-500 THB / US$8-14 Music: Psytrance, goa, ambient Vibe: Remote, psychedelic, hippie. The boat-only access creates a natural filter -- you won't get casual crowds here. If you're into psytrance, this is the one.

Jungle Experience

When: Twice monthly Where: Forest venue near Srithanu Crowd: 1,000-3,000 Entry: 500-800 THB / US$14-22 Music: House, techno, world music Vibe: Boutique forest party. Smaller, safer, more intimate.

Quick Comparison

| Factor | Full Moon | Half Moon | Shiva Moon | |--------|----------|-----------|------------| | Crowd | 10,000-30,000 | 3,000-5,000 | 500-2,000 | | Safety | Low-Medium | Medium-High | Medium | | Music | Mixed (commercial) | High (curated DJs) | Niche (psytrance) | | Glass/hazards | High | Low (managed venue) | Low | | Bucket list factor | High | Low | Low | | Price | 100 THB entry | 600-1,000 THB | 300-500 THB |

Koh Phangan Beyond the Party

Here's the thing about Koh Phangan that most guides skip: it's a genuinely beautiful island that deserves more than one drunken night. If you're coming for the Full Moon Party, stay a few extra days.

Beaches

Bottle Beach (Haad Khuat): The best beach on the island and one of the best in the Gulf. Accessible by longtail boat from Chaloklum (100-200 THB / US$3-6) or by a steep jungle hike (30-40 minutes). Crystal water, almost no development, proper paradise. Go early before the day-trip boats arrive.

Thong Nai Pan (Noi and Yai): Two beautiful bays on the northeast coast. Better swimming than Haad Rin, good restaurants, mellower vibe. Worth staying a night or two.

Haad Salad: Quiet beach on the northwest coast. Good snorkeling directly off the beach, a handful of restaurants, genuine relaxation.

Waterfalls

Than Sadet Waterfall: A series of cascading falls in Than Sadet National Park, historically visited by Thai kings. The carved royal initials on the rocks are unique. The hike through the jungle is the real reward. Entry: 100 THB (US$3) national park fee for foreigners.

Phaeng Waterfall: Closer to Thong Sala and easier to access. Two tiers with a swimming pool at the base. Best after rain (September-November). The viewpoint at the top gives panoramic island views.

Activities

Yoga and wellness: Koh Phangan is Thailand's yoga capital. Srithanu on the west coast is the center of it -- studios, retreats, raw food cafes, meditation centers. The contrast with Haad Rin is comical.
Snorkeling and diving: Sail Rock, between Koh Phangan and Koh Tao, is one of the best dive sites in the Gulf. Dive shops in Thong Sala and Chaloklum run day trips. Snorkeling is good directly off Haad Salad and Mae Haad (the sandbar connecting to Koh Ma islet).
Jungle trekking: The island's interior is dense jungle with trails connecting beaches. The hike from Thong Nai Pan to Bottle Beach is a classic.

Full Moon Party Night Timeline

Here's how the night typically unfolds:

| Time | What Happens | |------|-------------| | 5-7 PM | Pre-drinks at hostels. Groups form. Buy neon paint supplies, water bottles from 7-Eleven. Eat a big dinner. | | 7-8 PM | Body paint stations open on the beach. Early arrivals claim spots. | | 8-9 PM | Bars start pumping. Fire shows begin. Beach fills up. | | 9-10 PM | Party officially underway. All bars open. Entry fee collected at checkpoints. | | 10 PM-12 AM | Energy builds. Maximum density approaching. Bucket drinks flowing. | | 12-2 AM | Peak. The beach is shoulder-to-shoulder in places. Fire shows at full intensity. This is the Full Moon Party at its most iconic. | | 2-4 AM | Crowd thins as people tap out. More space to dance. Music gets heavier and better as the casual crowd leaves. | | 4-5 AM | Dawn crew. Dedicated dancers. Bars running low. | | 5-6 AM | First return ferries to Koh Samui. Songthaews filling up. | | 6-7 AM | Sunrise over the Gulf of Thailand. If you made it this far, watch it -- it's genuinely beautiful. Party winds down. Cleanup crews arrive. |

Is the Full Moon Party Still Worth It in 2026?

Honest answer: yes, if you've never been.

It's commercial. The music is mostly mainstream EDM and pop remixes. The beach is trashed by morning. The prices are inflated. The safety risks are real. All of that is true.

But there's still nothing quite like it. Twenty thousand people from around the world, dancing on a tropical beach under the moon, neon paint glowing under blacklights, fire spinning through the dark. The energy at midnight is undeniable. It's one of those experiences that's impossible to replicate at home -- loud, chaotic, beautiful, stupid, and alive all at once. As a first-time backpacker in Thailand, it's a rite of passage for a reason.

You should go if:

It's your first time and you want the full Thailand backpacker experience
You're in your 20s traveling with friends or a group from your hostel
You enjoy big, chaotic, messy parties and don't need curated DJ lineups
You want to check it off the list -- and you'll follow the safety basics in this guide

You should skip it if:

You hate crowds. At peak hours, parts of the beach are genuinely claustrophobic.
You're on a very tight budget. The inflated accommodation and drink prices sting.
You care about music quality. The Half Moon Festival has objectively better sound and DJs.
You don't drink and don't enjoy being around heavy drinking culture. You can absolutely go sober, but the atmosphere may wear on you.
You've been before and the novelty has worn off.

Quick Checklist

Screenshot this before you go.

Before the party:

Book Haad Rin accommodation (2+ weeks ahead minimum)
Eat a full dinner by 7 PM
Charge phone to 100%, bring power bank
Lock valuables in hostel locker
Buy waterproof phone pouch
Wear old shoes (NOT sandals)
Bring only: cash, phone, room key, passport COPY
Buy 2-3 water bottles from 7-Eleven
Agree on a meeting point with your group
Share live location on WhatsApp or Google Maps

During the party:

Watch your bucket being made (sealed bottles only)
Never leave your drink unattended
Do not buy drugs
Stay 3+ meters back from fire shows
Do not do fire jump rope
Do not swim drunk
Do not ride a motorbike
Check in with your group every 1-2 hours
Alternate drinks with water

After the party:

Hydrate aggressively (water, ORS packets, coconut water)
Check your feet and body for cuts and burns
Apply antiseptic (Betadine) to any open wounds
Inventory: phone, wallet, key -- everything accounted for?
Sleep. Your body needs it.
Monitor any wounds for infection over the next 3 days. Redness, swelling, or pus means see a doctor immediately -- tropical infections move fast.
