Koh Mak is a small, laid-back island south of Koh Chang in Trat Province. There is no airport and no car ferry, so everyone arrives by boat from the mainland or via Koh Chang and Koh Kood. The two mainland piers used for Koh Mak services are Laem Ngop and Laem Sok, both a short drive from Trat town and Trat Airport.
This updated 2026 guide explains how to get to Koh Mak from Bangkok, Trat and Koh Chang, including flight connections to Trat Airport, bus and minivan routes, private taxi prices, ferry and speedboat timetables, and detailed pier maps.

Bangkok to Koh Mak
Travelling from Bangkok to Koh Mak is straightforward. You can go overland by bus or minivan, book a combined bus + boat package, arrange a private taxi, or fly to Trat and continue by road to the pier.
1. Government Bus from Ekkamai
The government Bus 999 service runs from Ekkamai Bus Station in Bangkok to the Koh Chang ferry piers. It no longer stops directly at Laem Ngop, so a short taxi ride is needed from the Koh Chang ferry area to the Koh Mak pier.
| Departure | Duration | Cost | Notes |
|---|---|---|---|
| 07:45, 08:45 | 5–6 hrs | ~290 THB | Taxi needed to reach Koh Mak pier |
2. Direct Bus + Boat Packages (Bangkok → Laem Sok → Koh Mak)
Boonsiri offers combined tickets that include bus or minivan transport from central Bangkok or Khao San Road to Laem Sok Pier, followed by a direct ferry or speedboat to Koh Mak. This is the easiest option if you do not want to organise separate tickets.
| Operator | Departure | Total Duration | Price |
|---|---|---|---|
| Boonsiri Ferry | Morning | 7–8 hrs | 800–900 THB |
3. Private Taxi from Bangkok
Private taxis and minivans offer door-to-door transport from Bangkok hotels, Suvarnabhumi Airport or Don Mueang Airport to the Koh Mak piers. This is the most convenient option for families, groups, or travellers with a lot of luggage.
| Destination | Vehicle | Time | Price |
|---|---|---|---|
| Laem Ngop Pier | Car (1–3 pax) | 4.5–5 hrs | 3,500–4,500 THB |
| Laem Sok Pier | Car (1–3 pax) | 5–5.5 hrs | 4,000–5,000 THB |
| Laem Sok Pier | Minivan (up to 8 pax) | 5–5.5 hrs | 5,000–6,000 THB |
4. Fly to Trat Airport → Koh Mak
Flying to Trat and then transferring by road is the fastest and most comfortable way to reach Koh Mak. All Bangkok Airways flights are met by transfer services to the piers.
| Destination | Transfer | Cost |
|---|---|---|
| Laem Ngop Pier | Shared minibus | ~600 THB |
| Laem Sok Pier | Shared minibus | ~700 THB |

Return boats from Koh Mak to the mainland usually run in the late morning and early afternoon. Always check the latest times with your resort or booking agent, especially in low season.
Koh Chang to Koh Mak
In high season you can travel directly from Koh Chang to Koh Mak without returning to the mainland. Boats typically depart from Kai Bae or Bang Bao on the south coast of Koh Chang.
| Operator | Departure | Duration | Price |
|---|---|---|---|
| Kai Bae Hut | 09:00 | 1 hr | 600–800 THB |
| Bang Bao Boat | 09:30 | 1 hr 45 mins | 400–500 THB |
Services may be reduced or suspended in the rainy season, so if you are travelling between May and October it is often safer to go via the mainland.
Koh Mak ↔ Koh Kood
Many travellers visit both Koh Mak and Koh Kood in the same trip. Direct speedboats and inter-island ferries make it easy to hop between the islands in high season.
Direct Speedboat
| Route | Typical Times | Duration | Price |
|---|---|---|---|
| Koh Kood → Koh Mak | ~09:30 & 12:00 | 30–40 mins | 350 THB |
| Koh Mak → Koh Kood | ~09:40 & 13:40 | 30–40 mins | 350 THB |
Inter-Island Ferries
- Price: 500–600 THB
- Duration: 45–60 minutes
- Operated by Boonsiri, Seudamgo and Koh Kood Express
These services often form part of longer routes linking Koh Chang, Koh Mak, Koh Kood and the mainland, so it is worth booking in advance in peak season.

Practical Tips for Travelling to Koh Mak
- In high season (October–May) boats run frequently; in low season schedules are reduced and may change at short notice.
- There is no car ferry to Koh Mak. Motorbikes can sometimes be carried on certain boats for an extra fee, but cars must stay on the mainland.
- Koh Mak has limited ATMs and card acceptance, so bring enough cash from the mainland to cover your stay.
- Speedboats may be cancelled in rough seas. Larger ferries are usually more reliable in bad weather.
- Book ahead for peak holidays such as New Year, Chinese New Year and Songkran.
