When we think of a perfect vacation in Thailand, white sandy beaches, island paradises, fun and sun, and warm, inviting people with big smiles often come to mind. But don’t forget that Thailand is home to some of the best SCUBA diving and snorkeling in the world, thanks to the abundant and vibrant coral reefs and warm, crystal clear waters. Here are ten of our favorite diving spots in Thailand, many of which are close to Beach Republic on Koh Samui.

  1. - Hin Mouang

Known in English as ‘Purple Rock’, Hin Mouang is a feeding ground for pelagic fish, and is arguably the best dive spot in the whole of the Andaman Sea. The fastest way to get to the dive site is to do a live-aboard on a dive boat, or if you prefer to sleep on solid ground then your best bet is a two-hour boat ride from Koh Ngai. This spot features large and magnificently eerie underwater pinnacles that one can explore, as well as the steepest drop off in this part of the ocean. You can share the depths with soft corals, stunning anemone carpets, sharks, tuna, enormous barracuda massive shoals of fish, and gorgonians. Hin Mouang also boasts some very unique things, such as bryozoan. Bryozoan is clumps of white, straw-like things stand at around eight meters.

  1. - Hin Daeng

Hin Daeng, also known as ‘Red Rock’, is close to Hin Mouang and is comprised of walls, plateaus and rocks. Again, you can access the dive by doing a live-aboard, or two-hour boat ride from Koh Ngai. In this epic dive spot, you can see moray eels, octopuses, leopard sharks, grey reef sharks, barracuda, and an abundance of crawfish, shrimps. Nurse sharks, manta ray and whale sharks can also be found from time to time. Hin Daeng not only boasts an array of stunning sea creatures, but also some of the most stunning coral reefs in the whole country.

  1. - Chumpon Pinnacle

The best dive spot in the Gulf of Thailand, and easily accessible from both Koh Samui and Ko Tao, this spot has several underwater pinnacles. The shortest pinnacle stands at 16 meters and the tallest stands at 34 meters. The pinnacles attract many pelagic fish, such as barracuda, trevally, on occasion the mighty but humble whale shark. One of the most visually stunning dive spots in Thailand, Chumpon Pinnacle also boasts vibrant coral that stretches across the seabed some 30 meters below the surface, with the sun glinting off the silver scales of the many schools of fish that inhabit the area.

  1.  - Japanese Garden

Also accessible from Koh Samui and Ko Tao, the Japanese Gardens have large granite boulders that are covered in hard and soft corals, supporting a variety of colorful aquatic life, and is home to the hugely territorial Titan Triggerfish. As the island slopes away, at a depth of around 5‐8 meters, the boulders give way to a carpet of hard-tiered plate corals that extend down the incline to a depth of approximately 16 meters. The gardens are home to an array of stunning sea life, such as angelfish, butterfly fish, long‐fin banner fish, and wrasses that swim in and around the recently wrecked wooden boat.

  1. - Twin Peaks

Again, accessible from both Koh Samui and Ko Tao, Twin Peaks is named after two groups of granite rocks that are covered in corals and sponges. Clear sandy patches and a beautiful coral garden divide them. It starts at about 5 meters below the surface and drops to a depth of around 18 meters. Here you share the waters with stingrays, moray eels, pipefish, cleaner wrasse and many more. This is an ideal site for beginners, due to its depth, ease of navigation and the fact that the currents are week. The rocks are embedded into white sand and there is no shortage of marine life here. A friendly pair of rare saddleback clownfish can be found to the western side of the larger of the Twins.

  1. - Hin Nok

Hin Nok is comprised of a plateau with five pinnacles and a vast amount of gullies. It takes around an hour to swim right around the entire plateau. Again, a boat ride from Koh Ngai, Hin Nok is visited by turtles and is home to the very peculiar and feathery Ghost Pipefish. Not one to want to be spotted by a sea of divers (pardon the pun) not only does it not look anything like a fish, to further confuse you it sometimes floats upside down in the water. This dive spot is filled with whip corals, angelfish, moray eels, barracuda, and butterfly fish.

  1. - Koh Dok Mai

Located about halfway between Phuket and Ko Phi Phi, Koh Dok Mai is one of the top dive spots to do a night dive. The rocky island boats a unique and colorful undersea wall, a small cave, about five meters deep, which leads to a huge cavern with very strong currents, and a beautiful sloping reef. There is also an abundance of lobsters, so if you a keen eater of the luscious crustacean, you may want to look into hunting them here. The eastside of the island has an array of sea snakes, moray eels, and leopard sharks on the seabed.

  1. - King Cruiser

Accessible via a boat ride from Phuket, the King Cruiser wreck is a stunning dive spot. The 3,000-ton catamaran passenger ferry, hit Anemone Reef back in 1997. Within an hour the ship sank with no loss of life. It rests in an upright position with the steering house 10 meters from the surface and the propellers at 30 meters. It boasts some beautiful shoals of colorful fish, and some gorgeous coral.

  1. - Breakfast Bend

Named Breakfast Bend due to the fact that it is often the first dive of the trip, done immediately after breakfast. Breakfast Bend is located off the Similan islands, this dive spot has crystal clear turquoise water, fantastic visibility and a copious fish population. Here you can share the sea with the extremely poisonous, but non-aggressive, banded sea snake. It also homes scorpion fish, moray eels, triggerfish, leopard sharks, powder blue surgeonfish, barracuda, emperor angelfish, and shoals of glassfish.

  1. - Richelieu Rock

Often described as an ‘underwater cathedral’, Richelieu Rock in the Surin Islands is comprised of a horseshoe of rocky pinnacles that stand at around 30 meters high, with around one meter that breaks the water’s surface at low tide. It can have strong currents at times, so it’s best to keep your whits about you. The best way to experience Richelieu Rock is by live-aboard boat. This spot is famous for whale shark sightings, but also great spot for swimming with large schools of pelagic fish such as barracuda, batfish, and Jacks. Mantas can also be seen from time to time. The incredible harlequin shrimp, ghost pipefish, frogfish, and seahorses also frequent this great spot.
