Surat Thani to Koh Phangan

By the Viamo editorial team · Editor Terje Moy · Last updated July 2026 · 5 min read

Koh Phangan sits about an hour's sailing north of Koh Samui in the Gulf of Thailand, and getting there from Surat Thani is a straightforward business: a transfer to the mainland pier, a ferry crossing to Thong Sala, and you are on the island best known for the Full Moon Party and, increasingly, for its laid-back yoga retreats and quieter northern beaches. The key is booking ahead when the moon is full.

Which pier on the mainland?

Ferries to Koh Phangan depart from Donsak pier, roughly 1 hour 20 minutes east of Surat Thani town. Most travellers combine the road and sea legs by buying a joint bus-and-ferry ticket, which covers a minibus from Surat Thani town centre, Phunphin train station or the bus terminal to Donsak, and the onward crossing. These combined tickets are sold through travel agencies in Surat Thani, at the bus terminal, and directly on operator websites. Lomprayah also offers departures from Tapee pier closer to Surat Thani town, which can be useful if you are arriving by overnight train.

Operators and crossing times

Lomprayah High Speed Catamaran

Lomprayah is the most popular catamaran operator on Gulf routes. Their high-speed service from Donsak reaches Koh Phangan's main pier at Thong Sala in around 2 hours, calling at Koh Samui (Nathon pier) en route. Services generally run twice a day — morning and afternoon — with extra departures added in the run-up to the Full Moon Party. Lomprayah's combined tickets from Bangkok, Surat Thani and even Koh Samui are comprehensive and well-organised. If you are continuing to Koh Tao, the same catamaran goes on — see Surat Thani to Koh Tao for detail on the longer leg.

Raja Ferry Port

Raja operates a large car ferry between Donsak and Thong Sala. The crossing is slower — allow 5–6 hours — but the fare is lower and the boat is better suited to travellers with vehicles, motorbikes or bulky luggage. Raja sailings run once or twice a day; the overnight departure is a traditional way to travel if you are on a tight budget, as it saves a night's accommodation. The slow boat is considerably less comfortable than the catamaran in rough weather, however.

Seatran Discovery

Seatran operates a catamaran to Thong Sala that takes around 2–2.5 hours from Donsak, also calling at Samui en route. Like Raja, Seatran sells car-ferry passages for vehicles. Their timetables run in parallel with Lomprayah on most days.

Arriving at Thong Sala

All the main ferry services from the mainland arrive at Thong Sala pier, the island's commercial hub. There is a taxi rank immediately outside the pier, and songthaews (shared pick-up trucks) cover most of the island's main roads for a few baht per person. The popular beaches — Hat Rin in the south, Haad Yuan, Thong Nai Pan — are 20–45 minutes from Thong Sala by road, depending on road conditions. Hat Rin, the heart of the Full Moon Party, is in the far south-east and takes about 45 minutes by songthaew, or you can take a boat taxi direct from Thong Sala pier — a faster option.

The Full Moon Party: booking ahead is essential

Koh Phangan hosts the Full Moon Party roughly once a month, drawing tens of thousands of visitors to Hat Rin beach for a night. In the days before and after, ferry crossings from the mainland and from Samui fill up fast — sometimes days in advance. If your travel dates coincide with the Full Moon:

• Book your ferry well ahead, ideally as soon as you confirm your dates. Lomprayah's website and major booking platforms both sell Gulf ferry tickets in advance.
• Expect higher-than-usual prices and reduced flexibility for last-minute changes.
• Consider arriving on the island a day or two before the party to secure accommodation — Hat Rin rooms go quickly.
• The return journey after the party is equally congested. Ferries to Samui (a short hop) or back to the mainland via Thong Sala depart frequently but fill early.

The Full Moon Party calendar shifts by a day or two each month. Check online before booking to confirm exact dates.

Coming from Koh Samui

If you are already on Koh Samui and heading to Phangan, you do not need to return to the mainland. Frequent short-hop services connect the two islands in around 30–45 minutes — see the Koh Samui to Koh Phangan guide for full detail on those crossings.

Seasonal notes

The Gulf of Thailand monsoon runs from roughly October to December, with November the most unsettled month. Car ferries and catamarans generally keep running, but rough conditions can delay or cancel individual services. The slow Raja car ferry is more comfortable than you might expect in a gentle swell, because its hull rides the waves rather than crashing through them the way a catamaran does — though in truly bad weather neither is pleasant. Always check the forecast if you are travelling in November or December, and allow a spare day if your schedule is tight. See ferries to the Thai islands for an overview of Thailand's monsoon patterns on both coastlines.

Frequently asked questions

How long does the crossing from Surat Thani to Koh Phangan take?

On a Lomprayah or Seatran catamaran from Donsak pier, the crossing to Thong Sala takes around 2 hours, including a stop at Koh Samui. The Raja car ferry is much slower — around 5–6 hours. Journey time on Lomprayah services from Tapee pier (near Surat Thani town) is longer, as the pier is further from Phangan.

Do I need to book ahead for the Full Moon Party?

Yes, emphatically. Ferry seats in the days around the Full Moon sell out well in advance. Book your outbound and return crossings as early as possible — waiting until the last day in Surat Thani to buy a ticket can leave you stranded or significantly delayed.

Can I take a motorbike to Koh Phangan?

Yes. Raja Ferry's car ferry accepts motorbikes and cars for a vehicle surcharge. If you are renting a motorbike on the mainland and want to take it to the island, this is the practical option. Catamarans do not carry vehicles.

Is there a direct service from Bangkok to Koh Phangan?

Not on a single vehicle, but combined bus-and-ferry tickets from Bangkok's Khao San Road or the Southern Bus Terminal cover the whole journey in one booking. The total travel time — overnight bus to Surat Thani plus transfer and ferry — is typically 12–15 hours. Alternatively, fly to Surat Thani and take the ferry.
