Surin Islands
The two main islands are Ko Surin Nuea (North Island) and Surin Dtai (South Island) is about the same size and form, separated by a very flat, extended channel, which is only about one meter deep at low tide. As the tides wash fresh seawater between the two islands every day, reefs have recovered rapidly after coral bleaching in 2010. Now they offer excellent diving and snorkeling conditions again. In particular, the hard corals have bloomed in recent years and are home to countless animal species.
The entire archipelago of Surin covers an area of more than 320 km2 and also includes the great diving area at Richelieu Rock, where Manta Rays and Whale Sharks can be spotted.
Diving
If you want to see some of the best diving and marine life, the Surin Islands are the place to be.
Here are some of Thailand's most untouched and extensive reefs and corals. Here you will find turtles and fish species that aren’t found in the Similans or elsewhere. Some of the fish species are the Bumphead Parrotfish, the Napoleon Wrasse, the Yellow Masked Angelfish, the Barramundi Cod, and the Tomato Anemonefish.
If you decide to go diving in the Surin Islands, you do not have to worry about having to share the area with too many tourists.
Marine life
The Surin Islands were designated as a National Marine Park in 1981 and are a UNESCO World Heritage Site. Marine biologists pay the utmost attention to this park and its surroundings, which is obvious. If you dive here, you will find some of the most pristine coral reefs and marine life in Thailand.
Underwater, there is a great variety of creatures, such as Pickhandle Barracuda, Cardinalfish, Five-line Snappers, Twin Spot, Large Humpback Bream, Blue Spotted Pinefish, Mantis Crabs, White Tip Reef Sharks, Ghosted Pipefish of all kinds, Manta Rays, and Whale Sharks, just to name a very small selection.
The Surin National Park also includes Richelieu Rock, one of the best dive sites in the world.
The diving season lasts from October to May, although many recommend a visit between December and April. The rest of the year is usually rainy and windy, and the marine parks are closed.
