Huahin→Koh Phangan

The only direct route from Phuket to Koh Mook is by JOIN (shared) speedboat from Rassada Pier in Phuket Town to Koh Mook Pier — a proper concrete pier on the east side of Koh Mook. Three operators run daily direct services: Bundhaya Company, Satun pakbara Speed Boat Club, and Smart En Plus. The crossing takes approximately 2 hours 30 minutes for the 100+ km Andaman Sea hop, with most operators running a single morning departure around 08:30 from Rassada Pier. All vessels are 75-seat speedboats, sold as JOIN (shared) seats only — there is no private charter on this corridor. Bookings are open November through late April (high season); services reduce or suspend during the May–October monsoon.

The only way to travel from Hua Hin to Koh Phangan is a combined bus + catamaran ticket. Two operators run the route: Lomprayah High Speed Catamaran departs daily at 08:45 from its Phet Kasem Road office, and Boonsiri High Speed Catamaran runs twice daily at 01:00 (overnight bus) and 08:00 from its own office on the same road. Both combine a 40–55 seat highway bus to Chumphon with a 350–400 seat catamaran crossing to Thong Sala Pier on Koh Phangan, taking about 9 hours 30 minutes total door-to-door.

Morning departures arrive at Thong Sala Pier in the late afternoon. The 01:00 Boonsiri overnight bus option arrives around 10:30 AM and works well for travelers wanting to maximize their first day on the island. Book at least one day ahead; for full-moon party weeks, book one to two weeks ahead.

Both operators — Lomprayah and Boonsiri — charge the same ฿1,350 per adult for the combined bus + catamaran ticket from Hua Hin to Koh Phangan. Children travel at half price: Lomprayah charges ฿675 and Boonsiri charges ฿700. Infants under a certain age (typically 2 years) travel free on both operators.

The ticket price includes the highway bus from Hua Hin to Chumphon and the catamaran crossing from Chumphon to Thong Sala Pier. There is no separate fee for standard luggage (one carry-on plus one checked bag up to 20 kg), but excess bags cost ฿100–200 each at the pier. Onward transport from Thong Sala Pier to your resort on Koh Phangan is not included — songthaews from the pier cost ฿100–300 per person.

The total travel time from Hua Hin to Koh Phangan is about 9 hours 30 minutes. The journey is split into two legs: a 4-hour highway bus from Hua Hin to Chumphon, then a 3h 30m catamaran crossing from Chumphon to Thong Sala Pier. Door-to-door times include hotel pickup in Hua Hin and the songthaew or taxi transfer from Thong Sala Pier to your resort on the island.

The 08:00 Boonsiri and 08:45 Lomprayah morning departures arrive at Thong Sala Pier around 17:30–18:00, leaving the evening free for settling in. The 01:00 Boonsiri overnight bus arrives around 10:30 AM and is a good fit for travelers who want to start exploring the island the same day. Sea conditions in the June–October rainy season can extend the catamaran crossing by 30–60 minutes.
