Fares rise at weekends: the Saturday at the end of October cost THB 3,838 on some departures. A couple of flights, at 07:30 and 18:55, are listed at 1 hour 35 minutes, so check the length before you book.

The cheaper way: fly to Surat Thani

Thai AirAsia and Thai Lion Air both fly direct to Surat Thani. A Thai Lion Air flight from Don Mueang cost THB 1,110 one way. Once you land, buy the ferry ticket at the Raja booth in the airport; the ticket to Lipa Noi is THB 550. Together that comes to about THB 1,660 in all, and the crossing takes about 1 hour 30 minutes.

For the boat leg itself, see the Surat Thani to Samui ferry page, and for onward fares to the other gulf islands, the ferries by operator page.

The train, if you want a bed

Train 43 is the daytime run: it leaves Krung Thep Aphiwat at 07:30 and reaches Surat Thani at 16:20, for THB 524 in a 2nd class air-conditioned seat. Overnight, train 39 leaves at 22:50 and arrives at 07:50. For a bed, train 171 has a 2nd class air-conditioned sleeper at THB 654 upper or THB 724 lower. The station is still a ferry ride from the island, so use the ferry page above for the last stretch.

The cheapest: bus and ferry

A joint ticket is the lowest fare: Transport Co (999) starts from THB 689, and Lomprayah from THB 1,200. Set aside around 14 hours, because the bus stops at Chumphon Pier and you then take a ferry to Samui.

With Lomprayah, the bus leaves from its office on Khao San Road. Keep your original ticket, because you check in again at the Lomprayah office at Chumphon Pier before boarding the ferry.
