Bangkok – To/From Laem Ngop Area – 999 Bus
Using the public bus, the most economical way of getting from Bangkok to Laem Ngop (Krom Luang) Pier, the departure point for Koh Mak, is with the 999 Express, 329bt per person.
To Laem Ngop
The bus leaves at 07.45 from the eastern bus station, Ekamai (Sukhumvit 63), via Suvarnabhumi Airport Bus Station (08.20) and travels direct to the Koh Chang Thammachat Pier, arriving at 13.30. The bus may continue onto Laem Ngop Pier Pier, check when buying the ticket and ask the staff on the bus – they are very friendly and helpful.
If not, you take a songthaew share taxi at 80bt per person to Laem Ngop Pier (about 20 minutes) or 300bt for the charter.
You may make the 14.00 Leelawadee speedboat, otherwise you need to fall back on the 16.00 Panan. All speedboats are 550bt per person, children under 130cm 350bt, under 100cm free. Note: all Leelawadee services are suspended indefinitely, May 26 onwards)
From Laem Ngop
The return bus service leaves from Thammachat Pier at 14.30. To make that connection, you need the 10.00 Panan docking at 11.00 or the 11.30 Leelawadee docking at 12.30. Note: all Leelawadee services are suspended indefinitely, May 26 onwards)
The bus does park up at the bottom of Laem Ngop pier so you should be able to jump on here. If not, same as above, you use a songthaew taxi to Thammachat.

By Seudamgo to and from Laem Sok
Seudamgo runs a bus at 07.00 from Bangkok (Khao San Road) to Laem Sok Pier, calling at Rama 9 ( 06.00) and BKK Suvarnabhumi Airport (06.30).
This connects to the 14.30 mini catamaran which goes via Koh Mak (Ao Nid Pier, 15.15) and on to Koh Kood (Ao Salat Pier, 16.00). It’s 1,100bt per person, all in for both the bus and the boat.
The return from Koh Mak (Ao Nid Pier) to Bangkok is with the 09.00 boat (Ao Nid Pier), connecting to the 10.30 bus at Laem Sok. It’s the same price, reaching Khao San at 19.00 (via BKK).
From 1/6/25 to 30/9/26, though both the buses and boats operate, the Koh Mak option is not available (both directions).
By Boonsiri Bus to and from Laem Sok
Boonsiri‘s service departs from the Khao San area at 05.00 (11.15 on the island) and 08.00 (15.45). Returns are 09.00 and 13.00 (Bangkok at 17.30 and 20.30 depending on traffic). It’s the same price as Seudamgo, 1,100bt all-in.
From 1/6/26 to 30/9/26, only the 05.00 is running for the 11.00 boat (revised time for rainy season so 11.45 on island) and the return is only at 10.00 from the island for a bus at 11.00.
By Koh Kut Express to and from Laem Sok
Koh Kut Express has a service at 05.00 from Khao San Road via BKK Suvarnabhumi Airport (06.00) which connects to its 11.45 mini catamaran, 30 minutes to Koh Mak and then onto Koh Kood for 12.45. It’s 1,100bt.
The return is at 09.30 (09.00 from Koh Kood) reaching Laem Sok at 10.00 for the waiting bus, again at 1,100bt and calling at BKK too.
From 1/6/25 to 30/9/26, though both the buses and boats operate, the Koh Mak option is not available (both directions).
By SWB Bus from Suvarnabhumi Airport to Koh Chang Pier
Suvarnabhumi Bupara Co (SWB) has a direct microbus connection from Suvarnabhumi Airport Terminal to Koh Chang at 07.00 and 11.00 priced at 650bt for delivery to your resort on Koh Chang.
You could use the early 07.00 service and then ditch the last part of the ticket, instead taking a songthaew taxi from the Thammachat Pier to Laem Ngop Pier in time for the afternoon speedboats to Koh Mak. With the 07.00, SWB do sometimes allow a fare reduction if you explain that you do not need the Koh Chang ferry and delivery.
Keep an eye on the timetable in rainy season as they may reduce to one service only per day due to low numbers.
***We do NOT book this SWB service ***
By Public Bus from Bangkok to Trat
The next option is the public bus run by Cherdchai from Ekamai Bus Station Bangkok to Trat, 315bt per person.
If you took the 23.30 night bus, you would make either the 10.30 Leelawadee (if running) or the 11.30 Koh Mak Ferry speedboat. An early morning departure at 05.00 onwards should be OK for the 12.30 Panan (high season only, check if running). If not, you can fall back on the 14.00 Leelawadee (if running). An 07.00 departure would make the 16.00 Panan. Note: all Leelawadee services are suspended indefinitely, May 26 onwards)
When getting your bus ticket, explain that you want Koh Mak and they drop you out at Saen Tung Junction, which is about 35 km from Trat. From here, you take a songthaew taxi at around 80bt per person to the pier.
There are also two options specifically at 05.00 and 07.00 which head to Laem Sok Pier for a Koh Mak connection.
Otherwise, travel down slowly and spend a night in Trat and leave the next morning with a taxi to the pier (50bt), but check the Koh Mak ferry and speedboat timetables first.
From Morchit Bus Station, there are two daily buses as below, but you will not make it on time for a boat connection.

Run by Kohchang Bangkok Transport Company, there is a microbus service running from 05.00 till 18.30 which leaves from Ekamai Bus Station to Trat.

An identical service from the same company also goes from Morchit New Van Terminal to Trat Bus Station. The New Van Terminal is opposite the Bus Terminal so you need to use the over-crossing to reach it. Eastern Thailand services leave from Terminal Building C.
You will require one from 05:00, 06.30 and 08.00, with the change at Saen Tung. There are other times up until 18.30 to Trat.
