Explore Koh Haa

Ko Haa, meaning “five islands”, boasts some of Thailand’s best diving. What makes it so special is that its remoteness keeps it free from crowds and mostly untouched, while still being close enough to visit by boat.

Offering plenty for beginners and experienced divers alike, including some of the best macro sites in the area and year-round stunning visibility averaging around 25 meters, the 12-or-so dive sites boast healthy reefs, breathtaking drop-offs, walls, boulders, pinnacles and caves, shallow lagoons and intensely vibrant marine life.

The scuba diving highlights here are The Lagoon, The Cathedral and The Chimney, which are the most popular sites. Experienced divers can marvel at deep caves, while beginners can take their first underwater breaths in the relaxing lagoon reefs. With lots of varied training sites, it’s a great location to take dive courses, from entry-level to advanced courses.

Dive centers and resorts based in nearby Koh Lanta are frequent visitors to Koh Haa, though some liveaboard cruises from Phuket and Krabi too. Liveaboard safaris often include the island as part of a tour of the best dive sites in the Andaman Sea, which include the King Cruiser Wreck, Shark Point, Anemone Reef, Koh Doc Mai, Koh Phi Phi’s Bida Islands, and of course, Hin Daeng and Hin Muang.

Dive Activity

Diving in Koh Haa

Reef diving is excellent here, particularly at sites like The Lagoon, where the sunlight illuminates the corals. Many of the sites are multilevel dives, where novices can explore the shallows and others can delve deeper. Advanced divers can discover some of the many cave diving spots in the area, where interconnecting tunnels, chambers and swim-throughs create some impressive topography.

Top Koh Haa Dive Sites

Diverse Indo-Pacific life dominates Koh Haa, from macro cuties like nudibranch, ghost pipefish and shrimp, to schools of snapper, barracuda and colorful reef fish, such as angelfish, parrotfish, grouper, batfish, anemonefish and pufferfish. Tropical species like eels, sea snakes and octopus can also be spotted, while sandy areas are refuge for stingrays and even leopard sharks. Turtles and reef sharks can be seen, and even occasional manta rays and whalesharks make appearances.
