Full Moon Party from Koh Samui — Dates, Boats & Getting Back the Same Night

Overview

A full moon party from Koh Samui works, but it means a return night boat, not a day trip. Boats leave Samui’s Big Buddha (Bang Rak) pier in the evening, land at Haad Rin on Koh Phangan, and the only way back the same night is a party speedboat running on a rough hourly schedule between 01:00 and 05:00. Round-trip transfers run roughly 1,000-1,500 THB (~29-43 USD), on top of the 200 THB (~5.50 USD) beach entry fee paid in cash at the gate.

This page is the logistics, not a party review: which boats actually run this route, what they cost, when the last one back leaves, a checked 2026-2027 dates table, and what it costs to skip the boat entirely and sleep on Phangan instead.

Key takeaways

• Round-trip night boat: ~1,000-1,500 THB (~29-43 USD), departing Samui 18:00-23:00, returning 01:00-05:00.
• Next confirmed dates: 26 Sep, 27 Oct, 24 Nov, 24 Dec 2026, then a full 2027 calendar below — cross-checked against two independent sources.
• Some full moon dates fall on Buddhist alcohol-ban days and shift by a day — see the Buddhist holiday calendar.
• A fatal boat collision returning from the party happened off Bo Phut in July 2024 — the 3 AM crossing is the real risk on this trip, not the party itself.
• Sleeping over on Phangan often costs less than the night boat once you compare an honest budget, but most Haad Rin beds require a 4-5 night minimum booking during the party.

Full Moon Party Dates 2026 and 2027

The next confirmed Full Moon Party dates from September 2026 are 26 September, 27 October, 24 November and 24 December 2026, plus a 31 December New Year Countdown Party — figures cross-checked against the official Full Moon Party Thailand schedule and fullmoonparty-thailand.com as of September 2026. Both independent listings agree on every 2026 date.

The Haad Rin Business Association’s official rule is that any party landing on a major Buddhist holy day (Wan Phra Yai) is “postponed to the day following that Buddhist holy day.” The clearest example: the natural full moon in February 2027 falls on 21 February — the same date as Makha Bucha, a nationwide alcohol-ban day — so the party moves to 22 February instead. The same pattern pushed October 2026’s party to 27 October, a day after Ok Phansa (26 October). Always reconfirm the date within a week of travel; both source sites flag 2027 dates as provisional until the Association publishes final confirmation.

Boat Operators — Koh Samui to Haad Rin

Two different kinds of boat cover this route, and mixing them up is the single biggest planning mistake: a scheduled daytime ferry that also runs on party nights, and dedicated party speedboats that only run in the evening and small hours.

Prices above are as of September 2026, sourced from operator booking pages and Full Moon Party Thailand’s travel guide; expect a 10-20% premium on the 31 December Countdown Party.

Haad Rin Queen — the scheduled ferry option

Haad Rin Queen is the only regular ferry that lands directly at Haad Rin pier instead of Thong Sala — see the full Koh Samui to Koh Phangan ferry comparison for every operator on this route. Its last sailing back to Samui on a normal day is mid-afternoon, so it gets you to the party but will not bring you home afterward — book it only if you’re staying over or pairing it with a separate night boat back.

Party speedboats — direct round-trip packages

Dedicated party-night operators sell a round-trip package that includes hotel pickup, the boat, and basic insurance, departing Samui in the early evening and returning on a rolling schedule from 01:00 to 05:00. A round trip runs roughly 1,000-1,500 THB (~29-43 USD); one-way tickets cost slightly less but leave you stuck negotiating a return fare at the pier at 3 AM, which is the worst possible time to negotiate anything. Buy round trip, always.

Getting to Big Buddha and Bang Rak piers

Both departure piers sit on Samui’s northeast coast near Wat Phra Yai — see the full ferry pier guide for exact locations. From Chaweng it’s a 15-20 minute taxi (~200-300 THB); from Bophut or Choeng Mon, 5-10 minutes (~100-150 THB); most party-boat packages include this leg as a free hotel transfer, which is worth confirming before you book a separate taxi.

The 3 AM Crossing — What It’s Really Like

The boat back is the real risk on this trip, not the party. Return sailings run on a loose hourly window between 01:00 and 05:00, piers are dark and overcrowded, a share of the passenger load is heavily intoxicated, and life-jacket enforcement is inconsistent across smaller operators — none of that changes because the crossing happens at night instead of during the day.

This isn’t a hypothetical. On 22 July 2024, two speedboats collided roughly one nautical mile off Bo Phut, Koh Samui; one boat, the Chor Chokchanita 22, was returning from a full moon party run to Haad Rin when it struck the Bangkok Samui 2. One passenger, Kriengkai Somboonying, later died of his injuries, and two others were hurt (Bangkok Post; Thaiger). The Gulf of Thailand also gets genuinely rough in the October-December monsoon, when smaller wooden-hulled boats rock hard in swell — see our is Koh Samui safe guide for the island’s broader safety picture.

Practical steps that actually help: pick an operator running larger, covered boats over open longtails; sit low and central rather than at the rail; keep your ticket and phone in a waterproof pouch; and treat “the last boat leaves at 5 AM” as a soft promise — budget for it running late, not early.

Full Moon Party Without Staying on Koh Phangan

Doing the party as a night trip from Samui is entirely possible, but it means accepting a rough return crossing in exchange for skipping Phangan’s inflated party-week accommodation prices — the trade only makes sense if you value your own bed on Samui over sleep that night. Compare it honestly against the alternative below before booking.

If your trip is centered on Samui and you only want one full moon night, the boat is usually the cheaper option once you factor in Phangan’s minimum-stay booking policies during the party. For a broader side-by-side of the two islands, see Koh Samui vs Koh Phangan.

Sleeping on Koh Phangan Instead

Booking a bed on Koh Phangan for the night removes the 3 AM crossing entirely, at the cost of higher prices and a booking headache. Haad Rin dorm beds normally run 350-900 THB (~10-26 USD) a night, but most hostels and guesthouses impose a 4-5 night minimum stay during the party week, pushing a genuine one-night visit to roughly 1,750-4,500 THB (~50-129 USD) just for the bed. Mid-range hotel rooms run 1,400-3,500 THB (~40-100 USD) a night under the same minimum-stay terms.

Booking early matters more here than almost anywhere else on this route — rooms within walking distance of Haad Rin beach sell out weeks ahead of a confirmed date, and last-minute arrivals often end up 20-30 minutes away by songthaew, undercutting the whole point of staying over.

Common Mistakes and Scams to Avoid

The most common problem on this route isn’t the party, it’s the boat ticket. Unlicensed touts around Chaweng and Lamai sell “guaranteed” one-way return tickets for full moon night that don’t correspond to any real boat, and inflated last-minute pier prices are common once operators sense a captive, drunk crowd at 2 AM — see our general scams guide for how these tactics work islandwide.

• Buying one-way only: leaves you negotiating a return fare at the pier at 3 AM, the worst possible bargaining position.
• Trusting a street tout over a hotel desk or the operator’s own site: hotel-booked transfers are traceable if something goes wrong; cash-in-hand street tickets usually aren’t.
• Assuming Haad Rin Queen’s daytime schedule covers the return leg: it doesn’t run a 1-5 AM sailing — that’s a different, party-specific boat entirely.
• Skipping the beach entry fee in your budget: 200 THB (~5.50 USD) cash, paid at the gate, on top of the boat fare.

FAQ

Can you do the Full Moon Party from Koh Samui without staying overnight on Phangan?

Yes. Party-specific night boats leave Samui’s Big Buddha and Bang Rak piers in the early evening and return on an hourly schedule between 01:00 and 05:00. Round-trip tickets cost roughly 1,000-1,500 THB (~29-43 USD), plus the 200 THB (~5.50 USD) cash entry fee at the Haad Rin gate. Book round trip, not one-way — negotiating a fare at 3 AM is a bad position to be in.

What are the confirmed Full Moon Party dates for the rest of 2026?

26 September, 27 October, 24 November and 24 December 2026, plus a 31 December New Year Countdown Party at Haad Rin. These dates are cross-checked against the official Full Moon Party Thailand schedule and a second independent listing as of September 2026, and both agree. Reconfirm within a week of travel since the organizing association can adjust dates.

Does the Full Moon Party ever get moved because of a Buddhist holiday?

Yes. When the natural full moon lands on a major Buddhist holy day, the Haad Rin Business Association pushes the party to the following night. This happened in October 2026 (Ok Phansa on 26 October moved the party to 27 October) and will happen again in February 2027 (Makha Bucha on 21 February moves the party to 22 February). See the full Buddhist holidays and alcohol-ban calendar for every ban date.

How much does the boat from Koh Samui to Haad Rin cost?

A round-trip party speedboat runs roughly 1,000-1,500 THB (~29-43 USD), departing Samui in the evening and returning 01:00-05:00. The scheduled Haad Rin Queen daytime ferry from Big Buddha pier costs less, around 400-1,000 THB (~11-29 USD) round trip, but its last return sailing is mid-afternoon, so it only works if you’re staying over or arranging separate transport back.

Is the night boat back from the Full Moon Party safe?

It carries real risk. In July 2024, two speedboats collided about one nautical mile off Bo Phut, Koh Samui, with one boat returning from a full moon party run — the collision killed one passenger and injured two others. Pick operators running larger, covered boats over open longtails, avoid the most crowded departure window, and budget extra time rather than relying on the last advertised sailing.

Is it cheaper to sleep on Koh Phangan than take the night boat?

Usually not, for a single party night. Most Haad Rin accommodation enforces a 4-5 night minimum stay during the party, pushing even a dorm bed to roughly 1,750-4,500 THB (~50-129 USD) total. A round-trip night boat plus entry fee typically costs 1,200-1,700 THB (~34-49 USD) with no room booking required, making it the cheaper option unless you plan to explore Phangan beyond the party itself.
