Koh Phangan Travel Tips
When to go, how to book, what it costs

🔄 Updated 21 Jun 2026

Koh Phangan sits in the Gulf of Thailand off Surat Thani, between Samui and Koh Tao. Its charm is having two worlds on one island: the south around Haad Rin is all about the party scene, while the north and east are quiet, laid-back, and good for resting up or doing yoga. Before you book your boat ticket, there are just a few things that — if you know them in advance — make the trip a lot smoother.

When to go and what the weather's like

The best weather runs from December through April — clear skies, little rain, calm seas, temperatures around 28-32°C. Easy diving and easy island-hopping by boat. This is peak season in full swing, so it's also the busiest and most expensive, especially from late December through February.

The stretch to avoid if you don't want to gamble on rain is October through November, which is the Gulf of Thailand's rainy season. Heavy downpours come in waves, the sea gets choppy, and some inter-island boat departures may be cancelled. The tail end of the rains can sometimes drag into early December. If you're on a tight budget and can stomach the rain risk, this is when rooms drop hard because it's low season.

• Dec-Feb — best weather, pleasantly cool, but packed and rooms at their peak. Booking ahead is a must.
• Mar-Apr — still dry and sunny, getting hotter. April brings Songkran and another crowd surge.
• May-Sep — sun and rain in turns, prices easing off, the sea still good day to day.
• Oct-Nov — heaviest rain, roughest seas, cheapest rooms. For travellers who can handle the rain risk.

Full moon nights 2026 — check the date before you book

The Full Moon Party is held at Haad Rin every month on the night of the full moon, and it's the single biggest thing that swings room prices across the whole island. Around full moon nights, rooms fill up fast and prices climb — especially on the Haad Rin side, where you may be required to book a minimum of several nights. If you want to go to the party, lock in your dates clearly first. And if you want to skip it, you still need to check the date so you can plan around it.

The approximate Full Moon Party dates announced for 2026 are 29 Jun · 31 Jul · 28 Aug · 26 Sep · 27 Oct · 24 Nov · 24 Dec, plus an extra New Year countdown party on the night of 31 Dec.

Getting to the island

Almost all boats dock at Thong Sala, the island's main pier. There are two main routes in: from the mainland on the Surat Thani side, or a short hop from Koh Samui.

• From Surat Thani — speedboats from Tapi or Don Sak piers, around 2.5-3 hours, with several departures a day from multiple companies (Lomprayah, Raja, Seatran).
• From Koh Samui — boats from Maenam or Bang Rak pier reach Thong Sala very quickly, around 20-40 minutes. Good if you fly into Samui and connect by boat.
• From Koh Tao — speedboats heading south to Thong Sala, around 1-1.5 hours. Good for travellers doing all three islands in one go.

How to book a room without slipping up — especially around party nights

Room prices on Koh Phangan swing on three things: season, full moon nights, and location. To be blunt, the same room can cost nearly double in peak versus low season, and around full moon nights Haad Rin is where prices spike and booking conditions get strictest.

• For full moon nights, book weeks ahead — the Haad Rin side fills fast and often has minimum-stay requirements of several nights. Check the conditions carefully before you hit book.
• Want quiet? Pick the north or east side — Thong Nai Pan, Chaloklum, and Srithanu are quieter, and you can still ride over for the party for one night.
• Compare across platforms — the same room can vary by date and channel. Compare before you decide.
• Have a rainy-season backup plan — if you're travelling during the rain-risk window, picking a free-cancellation room gives you more peace of mind.

Safety you really need to know

Koh Phangan can be a blast, but there are spots where you genuinely need to be careful — especially around motorbikes and drinking. We'll be straight with you, because this is about your own safety.

• Riding on steep roads — the routes to Haad Rin and Thong Nai Pan are very steep, and sand and gravel on the bends are one of the top causes of accidents. Beginners should ride slowly, use the brakes a lot, and avoid the steep roads if you're not confident.
• Wear a helmet and carry a licence — an international driving permit and insurance help a lot if something goes wrong. Police set up checkpoints from time to time.
• Never drink and ride — most accidents happen while drunk, especially on the late-night ride back from the party. If you've been drinking, take a taxi or shuttle back.
• Watch out at night — roads are dark, with people and dogs crossing and lots of sharp bends. Ride slowly to be safe.
• Drink with your wits about you and mind your valuables — party nights are crowded, so carry only the cash you'll use, keep your passport and valuables in the safe, never leave a drink unattended, and go in a group with friends.
• Swim with care — during the monsoon the waves are strong and there are currents. Watch the warning flags and don't get in the water drunk.

What a day really costs

A Koh Phangan budget stretches anywhere from backpacker to laid-back-with-comforts, depending mainly on the season and your travel style. The figures below are rough estimates per person per day, not including the boat ticket to the island — and they'll climb during high season and full moon nights.

Roughly speaking, backpackers can keep it to around 800-1,200 THB a day (not counting party nights), while if you go for a nicer room and hit the cafés often, you're looking at around 1,800-3,000 THB and up per day. All of this climbs in high season and around full moon nights.

Pre-trip checklist

• Pick your timing — aim for Dec-Apr if you want good weather, avoid Oct-Nov if you're worried about rain.
• Check the real full moon date on the organiser's page, then decide whether to join the party or skip it.
• Book your boat and room ahead, especially around high season and party nights.
• Sort out an international driving permit and helmet, and check that your travel insurance covers motorbikes.
• Set a daily budget and keep party-night money separate; carry only the cash you'll use.
• Photograph the bike's scratches before you take it, and keep valuables in the safe.
