HTMS Chang Wreck - Formally known as the USS Lincoln County, HTMS Chang is Thailand’s longest wreck at 117 metres / 384 feet and sits at 30 metres / 100 feet underwater. After more than 50 years’ service in the Royal Thai Navy, it was sunk in 2012 to create an artificial reef. It’s a great site with lots to explore including cabins, briefing rooms and the main holding area. The wreck is also home to a wide variety of marine life including barracuda, octopus, batfish, groupers and a range of interesting critters.

Hin Luk Bath – Considered by many to be one of the best dive sites around Koh Chang, this rock pinnacle site attracts schooling fish and is home to moray eels, sting rays, groupers, barracuda as well as more colourful species such as parrotfish, angelfish and damsels. The boulders surrounding the pinnacle have created interesting canyons and crevices which make ideal shelters for hiding fish and critters. 

Hin Raab South (locals call it Hin Laab) - 5 km south of Koh Chang, Depth: average 11 / max. 16, Visibility: varies from 3 to 20m, often very clear water and great for snorkeling. This is a rocky site with good variety of coral around it. There are 3 dive sites in this area: one is a dive around the rock, a good place to spot turtle, batfish, stonefish, porcupine fish, stingrays, moray eels, often we see big barracuda. We also had quite a few whale shark spottings here. There is an abundance of soft coral. The second one off to the north is a bit deeper and richer in coral and has a lovely small canyon, called secret reef. Here we often see rays, morays, angelfish, groupers, triggerfish, anemone fish, parrotfish, turtle.

Koh Rang National Park - an area of multiple dive sites, one of which is Koh Rang Pinnacle. This site is well known for attracting passing pelagics including great barracuda, tuna and cobia. The pinnacle itself is surrounded by reef fish and when the sun’s rays filter down from the surface it is a stunning site for underwater photography. You’ll also find nudibranch, various shrimps, scorpionfish and other critters hiding out any suitable ledge. There are four other popular shallow dive sites at Koh Rang, with great coral reefs; Hin Kuak Mak, Koh Yak, Koh Laun, Koh Tong Lang.

T11 Wreck – Just next to Hin Raab, this 30 metre / 100 foot long Thai navy ship was sunk in 2013, giving Koh Chang its second wreck dive. The T11 lays within close proximity of Hin Raab at around 16 metres / 52 feet which makes it ideal for first time wreck divers. The wheel house, bridge, storage areas, main deck cabin and control room are all identifiable and the structure is now home to numerous species of reef fish.

What to see

Whilst wrecks are a big attraction in Koh Chang the marine life is no less impressive. Highlights include barracuda, groupers, sting rays, tuna and cobia together with a diverse range of critters, macro life and a plethora of colourful reef fish.

Most likely sightingsPossible sightings


There are two islands called Koh Chang in Thailand. This guide refers to the larger island located in northeast Thailand close to Cambodia. Koh Chang means Elephant Island and while there are elephants on the island they are not native. The name, in fact, refers to the shape of the headland. The island is part of a 51 strong archipelago. It’s 18 miles (30km) long and 9 miles (14km) wide. Coconut plantations were the mainstay and while tourism now is a big industry visitors to Thailand often overlook this island. It doesn’t enjoy the fame of other Thai islands, but that is not to say that this island is sleepy or undeveloped. Most recently the islands development seems to be focussed on catching up with Koh Samui and Phuket.

There are 14 areas, mostly located on the western side, from which you can choose to base yourself. Picking which location to stay at is key to a happy holiday. Like most Thai islands, it enjoys rich tropical vegetation and a central elevation peaking at around 2500ft (750m).

Other attractions

Koh Chang offers some good hiking and wildlife spotting options. Sailing and kayaking are also popular here and are fun ways to play on top of the ocean.
