Thailand’s eastern province of Trat is made up of 52 islands, out of which the most famous include Koh Chang, Koh Mak, and Koh Kood. The region is a favourite for holidaymakers and caters to all budgets. The islands feature luscious jungles, framed by pristine sandy beaches that are decorated with swaying palm trees, all surrounded by azure warm waters overflowing tropical marine life. The region offers plenty for divers and non-divers alike, making it an all-round desirable destination.

Whilst Trat is a popular spot, it’s not particularly overcrowded, which is great news for divers who love quieter, unspoiled dive sites. Many islands boast barely-explored sites, with extremely abundant marine life. Imagine colorful coral reefs, seething with tons of tropical creatures, from macro favourites like nudibranch and shrimp to larger animals like barracuda, turtles, grouper, reef sharks and even whale sharks. Many other common critters to encounter include angelfish, batfish, snapper, lionfish, octopus, moray eels, lobster, pufferfish, stingrays and so much more awe-inspiring animals. The topography is just as exciting, with drop-offs, boulders, caves, swim-throughs, tunnels, and pinnacles all to explore. Wreck lovers can also rejoice, as the island of Koh Chang in this region is home to Thailand’s largest shipwreck - the 100 meter-long HTMS Chang.

Trat offers divers some excellent reef dives, as well as captivating caves and encrusted wrecks, and typically experiences only mild currents. Scuba diving here is suitable for all skill levels, from absolute beginner to dive veterans. Thanks to clear waters, shallow sites averaging between 15-20 meters, and calm conditions, it’s a great place to obtain an open water license, while those wishing to get an advanced certification can easily do so, with plenty of appropriate training sites. Dive centers are aplenty and offer a myriad of options, like single and two-tank dives, and full-day trips. Boat diving is common, though shore dives are possible depending on location. Additionally, there are dive resorts to suit all manners of travelers.

Trat enjoys a wonderfully warm tropical climate, and as a result, diving is great all year-round, with average water and air temperatures lingering between 28°C-30°C (82°F-86°F). It’s said that the best period to visit the province, particularly for diving, is between March and June, which is the hot season, or the cooler, dry period from November to April. The wet season runs from June to October, but the diving is still great, as critters remain unchanged.

Trat contains some of Thailands top diving islands in this area  - such as Koh Chang, Koh Mak & Koh Kood, each one hosting numerous dive sites to explore.

One of the most famous sites in Trat is the HTMS Chang, accessible from Koh Chang, Thailand’s largest wreck, which hosts a ton of life, and is even visited by whale sharks in the high season.

Other unmissable sites in the region include Koh Raet, Hin Bang Bao, Hin Luk Bat, Koh Rang Pinnacles, the Thornburi Wreck, Koh Wai, Banana Rock, Hin Rap, Blueberry Hill and Hin Da Gaeng. On Koh Mak, you absolutely must not skip Koh Phe, which is the most popular site in that area.
