What Is the Half Moon Party?
The Half Moon Party (also called the Half Moon Festival) is one of Koh Phangan's best-known jungle raves, held roughly midway between Full Moon Parties in the island's monthly lunar cycle. Unlike the beach-based Full Moon Party at Haad Rin, the Half Moon Party takes place in a natural amphitheatre near Baan Tai, in the south of Koh Phangan, and draws a mix of first-time visitors and longtime fans of the island's party scene.
History and Atmosphere
The event grew out of Koh Phangan's wider full moon culture in the early 2000s, when organisers looked for a way to spread visitor numbers across the month rather than concentrating everyone on a single beach on one night. The result is a smaller, more contained party with UV-reactive stage design, elaborate lighting rigs and multiple sound stages playing psytrance, techno and house through the night.
Compared with the Full Moon Party, the Half Moon Party is easier to navigate: the venue is enclosed, entry is ticketed, and the crowd is generally smaller, which makes it a popular choice for travellers who want the island's party atmosphere without the scale of the main event.
When Is the Next Half Moon Party?
The Half Moon Festival runs several times a month on a schedule tied to the lunar calendar rather than fixed calendar dates. Because of this, listing specific 2025 dates here would quickly go out of date — always confirm the current month's date and ticket details through the official Half Moon Festival calendar or your ferry booking confirmation before travelling, since exact dates for 2026 can shift and were not confirmed at the time of writing.
How to Get to Koh Phangan for the Half Moon Party
Koh Phangan has no airport, so every visitor arrives by boat. Most travellers heading to the Half Moon Party reach the island by ferry from Koh Samui, which sits closest and has the most frequent connections, though routes from the mainland are also common.
Ferry from Koh Samui to Koh Phangan
Koh Samui is the fastest and most popular gateway to Koh Phangan. Ferries and speedboats depart from Samui's piers (commonly Bophut and Maenam) and arrive at Thong Sala pier on Koh Phangan, with some services also stopping closer to Haad Rin. Crossing times are short compared with mainland routes, and services run multiple times a day, making Samui the most convenient base if you're flying into Samui Airport or already island-hopping in the Gulf of Thailand.
Other Ways to Reach Koh Phangan
- From Surat Thani (mainland): combined bus/train-and-ferry tickets connect Surat Thani's bus terminals, train station and pier to Koh Phangan, useful for travellers arriving from Bangkok or southern Thailand by land.
- From Koh Tao: ferries running the Koh Tao–Koh Phangan–Koh Samui line call at Koh Phangan, a practical option if you're island-hopping down from Koh Tao.
- From Chumphon: ferry services also link Chumphon on the mainland to Koh Phangan, often paired with an overnight train or bus from Bangkok.
Exact operators, timetables and fares vary by season and route, so check live availability and current prices when you book rather than relying on printed schedules.
Tips for Attending the Half Moon Party
- Book your ferry in advance around party dates — boats to Koh Phangan fill up quickly in the days before and after a Half Moon or Full Moon Party.
- Arrange onward transport to the venue. The party site near Baan Tai is outside the main tourist strip, so most visitors get there by songthaew (shared taxi) or an organised transfer from their accommodation.
- Buy tickets ahead where possible to avoid queues at the gate, and keep some cash on hand as not all vendors on-site accept cards.
- Plan your accommodation early — rooms on Koh Phangan get scarce and prices rise around party dates, especially when a Half Moon Party falls close to a Full Moon Party in the same week.
- Watch your belongings and drinks as you would at any large outdoor event, and agree on a meeting point with your group in case you get separated in the crowd.
Booking Your Ferry to Koh Phangan
Whichever gateway you're travelling from, book your crossing before you head to the pier so you're not left waiting on standby during a busy party week. Compare the Koh Samui to Koh Phangan ferry schedule if you're coming from Samui, or check the Surat Thani to Koh Phangan ferry and bus combo tickets if you're arriving from the mainland. If you're timing your trip around both major parties, see our Full Moon Party guide for how the two events typically fall in the same lunar cycle.
