At the heart of this region is the Coral Triangle, a marine area that covers parts of Indonesia, Malaysia, the Philippines, Timor-Leste, Papua New Guinea, and the Solomon Islands. This area harbors nearly 600 species of coral and a vast array of marine life, making it a global hotspot for scuba divers.

These hidden gems are perfect for divers seeking adventure off the beaten path, where pristine reefs, wrecks, and unique underwater landscapes await. By exploring these quieter spots, divers not only enjoy uncrowded dive sites but also contribute to the local communities and help preserve their untouched ecosystems. Here are 10 hidden dive gems in Southeast Asia for your bucket list. Labuan, Malaysia. Located off the coast of Borneo, Labuan is a hidden wreck diving paradise. This area is home to several WWII wrecks, including the Australian Wreck, the American Wreck, and the Blue Water Wreck. These shipwrecks are adorned with vibrant soft corals and attract schools of fish. Despite its incredible wreck dives, Labuan remains off the radar for many divers, providing a quieter and more serene experience than Malaysia’s more popular dive spots. Labuan is also known to have manta rays, especially around dive sites in the Labuan Marine Park. Both reef and giant oceanic mantas have been sighted and the peak months for mantas are May to July. Best time to dive: March to October. Experience level needed: Experienced (strong currents and depth). Mu Ko Surin National Park, Phang-nga, ThailandPhoto by Notto Suthipat on Unsplash Mu Ko Surin, Thailand While Thailand’s Similan Islands steal the spotlight for diving in Thailand, Mu Ko Surin National Park, located further north, is a lesser-known gem. The Surin Islands are less visited than the Similans, ensuring a more pristine underwater environment and fewer divers. These islands offer incredible coral reefs and shallow dives with no currents. There are numerous sea turtles and a diverse array of coral landscapes to explore. At nearby Richelieu Rock, one of Thailand’s best dive sites for larger marine life, you can spot manta rays and whale sharks, and explore coral-covered landscapes teeming with fish. A liveaboard that combines diving in the Surin Islands with a trip to Richelieu Rock is a great combination for Advanced Open Water divers. You can enjoy easy diving at the Surin Islands and then work on your blue-water diving skills at the more challenging Richelieu Rock. Best time to dive: November to April. Experience level needed: All levels. Wakatobi, South East Sulawesi, IndonesiaPhoto by Benjamin L. Jones on Unsplash Pulau Weh, Indonesia Tucked away in the far north of Sumatra, Pulau Weh is a hidden treasure of diving in Indonesia. This volcanic island has a laidback vibe and offers an abundance of marine life, including blacktip reef sharks, manta rays, sea turtles, dolphins, pelagic fish, and a variety of critters. The reefs are full of healthy corals, and dive sites feature dramatic underwater topography with canyons, pinnacles, and swim-throughs. Best time to dive: May to September. Experience level needed: Experienced (strong currents and deep wrecks). Koh Rong Sanloem, Preah Sihanouk, CambodiaPhoto by allPhoto Bangkok on Unsplash Koh Sdach, Cambodia For a hidden gem in Cambodia, consider Koh Sdach. This tiny island, located in the Koh Kong Archipelago, remains largely off the tourist radar. The diving here is still relatively undiscovered, with healthy coral reefs and diverse marine life, including turtles, schools of fish, and colorful macro critters. The local dive operators focus on sustainable tourism, and the island itself has a more laid-back, traditional vibe compared to the growing popularity of dive spots such as Koh Rong Samloem. There are plenty of shallow, current-free dive sites, making Koh Sdach perfect for getting your diving license. Koh Sdach’s dive centers not only offer diving services but also engage in conservation efforts to protect the local marine environment. This island is a great choice for environmentally conscious divers who want to explore all that diving in Cambodia has to offer away from any crowds. Best Time to Dive: November to April. Experience Level Needed: All levels. Mergui Archipelago, Myanmar The Mergui Archipelago, located in the Andaman Sea, is one of Southeast Asia’s most secluded diving regions. With over 800 islands, this area offers unspoiled dive sites with crystal-clear waters, stunning coral reefs, and encounters with reef sharks, whale sharks, and rays. The Mergui Archipelago has been affected by overfishing in some regions, particularly in the northern parts. However, the southern areas of the archipelago, such as around the island groups closer to the Thailand border, tend to offer better dive conditions. Areas like Shark Cave, Black Rock, and North Twin Island are known for their healthy marine life and diverse underwater environments, making them some of the best spots to explore in the archipelago. These sites are more remote and less impacted by human activity, providing better chances to encounter sharks, manta rays, and other pelagic species, as well as vibrant coral reefs. Diving operators in the region are aware of the conservation challenges and often guide divers to the healthier southern dive sites. Diving in the southern Mergui Archipelago typically involves open-ocean diving and can feature strong currents, so it’s a good idea to get your drift diving certification and hone your buoyancy control skills before you go diving here.

This site is perfect for photographers looking to capture macro life such as frogfish, pipefish, and rare nudibranchs. The untouched waters of Timor-Leste also provide fantastic visibility and a quiet dive experience away from the crowds of more…
