Koh Phangan sits just north of Samui, and speedboats run between them several times a day, so you can plan loosely. You can go over in the morning and come back in the evening as a day trip, or cross over and stay one night to see more — which is the better value. This three-day plan takes the second option: Samui as your base on day one, a night on Phangan on day two, then back to Samui on day three. Scale it up or down to suit your energy and budget.
Read this before you board
The Gulf of Thailand has a monsoon stretch late in the year (roughly October to December) when winds pick up and boats can be cancelled or rescheduled at short notice. Before you travel, check the forecast and ask the pier about the latest sailings. If the sea is rough, don't push it — moving your dates is the safer call.
Samui–Phangan ferry: which pier, and how much?
Two main speedboat operators run from Samui to Koh Phangan: Lomprayah and Seatran Discovery. They drop you at Thong Sala, Phangan's main pier. The crossing takes about 30–45 minutes depending on the operator and the swell. A one-way ticket runs around 300–400 THB per person, and prices climb in high season and on the nights around the Full Moon Party.
- Bangrak pier — Seatran Discovery's main pier on the north side of Samui, near the airport and the Chaweng–Bophut zone. Several sailings a day.
- Nathon pier — on Samui's west side; Lomprayah uses this as its main pier. Handy if you're staying around Nathon or Taling Ngam.
- Maenam pier — some Lomprayah sailings leave from Maenam on Samui's north side, near the Maenam–Bophut area.
- Thong Sala pier — the arrival point on Phangan and its main port town, with motorbike rentals, songthaews, and places to stay nearby.
Which sailing should you book?
If you're staying overnight, book the morning sailing on day two and the afternoon or evening sailing on day three ahead of time — especially in high season (December to April) and on the nights around the Full Moon Party, when boats fill up fast. Booking online in advance and buying at the pier usually cost about the same, but booking ahead locks in your seat.
Book the activities in your Koh Samui trip ahead
Booking online ahead on Klook or GetYourGuide is usually cheaper than the gate and skips the queue. Pick only the experiences you actually want — prices and availability are shown live on each site.
Day 1 — Samui as your base, getting ready to cross over
Spend the first day on Samui without rushing. Knock out the highlights near the pier first, then cross over early the next morning. Pick a place to stay on Samui's north side (Bophut–Maenam–Bangrak) so you're close to the pier and don't have far to travel on day two.

Note: if you'd rather not switch hotels, you can do Phangan as a single day return. But you'll only have late morning to afternoon on the island, so you'll only fit a few stops in. Staying one night makes the further spots — like Than Sadet Waterfall or Bottle Beach — much more doable.
Day 2 — Cross to Koh Phangan and loop the island
On day two, take the morning boat over to Thong Sala, then rent a motorbike or hire a songthaew to loop the island. Phangan is bigger than you'd think, and some roads are steep and very twisty, especially heading to the beaches in the north and east. If you're not used to the roads, hiring a car with a driver is the safer bet.

About riding a motorbike on Phangan
Phangan's roads are notorious for being steep and slippery, especially heading to Haad Rin, Bottle Beach, and the viewpoints. Tourist accidents are common. If you're not confident on two wheels, don't risk it — take a songthaew or hire a car with a driver. A half-day island loop with a driver runs around 800–1,500 THB depending on distance, which beats risking a crash.
Full Moon Party — if your trip lands on the full moon
Haad Rin is where the Full Moon Party was born — a beach party held roughly once a month on the full moon. If your trip happens to fall on that night, the Haad Rin entry fee is collected at the gate, around 200 THB per person, and you get a glow-in-the-dark wristband. There are no advance tickets sold online — if a site claims to sell tickets ahead of time, assume it's a scam.
- The date moves around. Some months it shifts because it clashes with a major Buddhist holy day — check the exact date on the official site before you plan.
- Rooms that night are full and expensive. Book weeks ahead; prices jump noticeably.
- Mind your valuables. The party gets very crowded — watch your bag and phone, and don't go swimming alone while drunk.
- Watch what you drink. The bucket cocktails are strong on alcohol. Pace yourself, alternate with water, and never take a drink from a stranger.
If you'd rather skip the crowds, avoid crossing to Phangan on the nights around the Full Moon Party — boats fill up, rooms get pricey, and Haad Rin is packed. Go on a normal night and you'll get a much calmer version of Phangan.
Day 3 — Phangan morning, then back to Samui
On your last day, soak up Phangan's quiet corners in the morning, then take the afternoon boat back to Samui. Get to the pier at least 30 minutes before departure, especially if you have an onward flight from Samui later the same day — don't book a boat that cuts it too close to your flight.

What to prep and the overall budget
Rough cost per person (excluding accommodation and food): the round-trip Samui–Phangan boat runs about 600–800 THB, a one-day motorbike rental about 200–300 THB (or 800–1,500 THB to hire a car), Than Sadet Waterfall entry about 100 THB, plus a small viewpoint fee. All in, the transport for this plan comes to roughly 1,200–1,800 THB per person. Every price shifts with the season and high-season demand.
- Leave the heavy bags on Samui. Take a small bag for the one night on Phangan; most Samui hotels will hold luggage for you.
- Carry cash. Waterfall and viewpoint fees and the Haad Rin party entry are cash-only, and ATMs on Phangan charge hefty fees — withdraw on Samui first.
- Seasickness tablets. Take one 30 minutes before boarding; they help a lot when the swell is up.
- What to pack. Reef-safe sunscreen, a hat, closed-toe water shoes for the waterfall, and a rain jacket in the wet season.
- Drive carefully on both islands. The hillside roads are steep and slippery in the rain. Wear a helmet, ride slowly, check the rental's insurance before you take it, and use a car with a driver if you don't know the roads.
Adjust the plan to the time you have
Only 2 days — drop the first Samui day and cross to Phangan on the first morning, then head back on the evening of day two. · 4 days or more — add another night on Phangan to reach Bottle Beach (a longtail boat ride or a 1–2 hour hike) or take a boat onward to Koh Tao to dive.
