Koh Mak ( or Koh Maak in some guides ) is located in the Marine National Park in Eastern Thailand, around 40Km from the Trat coast and 20Km south of Koh Chang. It is around 16km², too big to walk around but easy to see by bicycle. The roads are very quiet as there isn’t a vehicle ferry to the island. Koh Mak is also relatively unknown. This means that it isn’t over run by package tours and and is still a well kept secret for most travelers.

Koh Chang is growing every year with more and more shophouses, bars, restaurants and nightclubs. Whereas development on Koh Mak is limited to small restaurants, minimarts and a few resorts. It’s growing but at a much slower pace.

Koh Mak is a quiet location for people who are looking for a relaxing holiday. If you are looking for long deserted beaches then you’ll find them on Koh Mak. There aren’t any jetskis or beer bars. So it isn’t for someone looking for an alternative to Phuket or Pattaya. The island has beautiful nature which is perfect for hiking trips. There is also a diving school where you can book diving and snorkeling trips. The nearby Marine Park has the best selection of marine life Thailand has to offer.
