Four routes at a glance

Bangkok Airways flies Suvarnabhumi to Samui in 1 hour 10 minutes from THB 2,752. The three other routes go through Surat Thani and cost less but take most of a day.

The ferry leg is on the Surat Thani to Samui ferry page. Fares between Samui and the other gulf islands are on the ferries by operator page.

Bangkok Airways direct flight

Bangkok Airways leaves Suvarnabhumi at 06:00 and lands at Samui at 07:10 on Tuesday 27 October for THB 2,968 one way. The same 06:00 flight on Tuesday 17 November is the cheapest sampled fare at THB 2,752.

The 07:30 and 18:55 flights are listed at 1 hour 35 minutes instead of 1 hour 10 minutes. Bangkok Airways advertises Samui flights from THB 2,500.

Fares move with the date. A weekday in November cost THB 2,752 and a Saturday at the end of October cost THB 3,470 to THB 3,838.

Fly to Surat Thani, then take the ferry

Thai AirAsia and Thai Lion Air fly direct from Bangkok to Surat Thani. Thai Lion Air leaves Don Mueang at 07:25 and lands at 08:40 on Thursday 29 October for THB 1,110 one way.

Flights to Surat Thani start from THB 803.

Raja has service booths at the Surat Thani and Nakhon Si Thammarat airports that sell a ferry ticket with the transfer to Donsak. A Surat Thani Airport to Lipa Noi ticket costs THB 550 on Raja.

The Thai Lion Air fare plus the Raja airport ticket comes to about THB 1,660 one way. That is an estimate: the flight fare changes with the date.

The Raja crossing between Donsak and Samui takes about 1 hour 30 minutes. The first sailing leaves Donsak at 05:00 and the last at 19:00, one every hour. The last sailing arrives at 20:30.

Bus and ferry joint tickets

Lomprayah runs six trips a day and Boonsiri and Transport Co run four each.

The Lomprayah bus leaves from its office on Khao San Road and takes about 8 hours to Chumphon Pier. At Chumphon Pier you check in again at the Lomprayah office with the same original ticket before boarding the ferry. About another 4 hours by boat brings passengers to Maenam Pier on Samui.

The other bus route goes to Donsak: the bus from Khao San Road to Donsak pier takes about 10 hours. From Surat Thani, the Lomprayah bus and catamaran from Tapee Pier to Nathon Pier leaves at 10:00 and 13:00 for THB 600. With the van to any hotel on Samui it costs THB 750.

The way back, Samui to Bangkok

A Lomprayah van, catamaran and bus from Pralarn Pier to Khao San Road leaves at 06:30 and arrives at 20:30 for THB 1,600. The VIP bus version of the 06:30 journey costs THB 1,900, and a 10:30 departure arrives at 00:45.
