Highlights
Best diving spots
Hin Daeng & Hin Muang, meaning Red Rock & Purple Rock, are two sea-mounts located south from Ko Lanta, right out in the Andaman Sea. They are Thailand’s deepest dive sites, plunging to between 50 & 70 metres and offer the chance to see larger pelagic life, with Manta Rays popular visitors & Whalesharks seen occasionally.
Even if the giants aren’t around though, these two dive sites are still teeming with life, with Tuna, Trevally, Rainbow Runner & Mackeral all hunting on the numerous smaller reef fish. Chevron & Yellowtail Barracuda lurk in the blue, while Batfish, Snapper, Morays & plenty critters also call these sites home.
Hin Muang is fully submerged, with its anemone-covered top at around 10m. It can receive strong currents and has little protection, so check conditions before you go. Hin Daeng is the larger of the two mounts & just reaches the surface. It offers greater protection and is the easier of the two sites to dive. Due to the depths, currents & exposed nature of the sites, they are only recommended from more experienced divers.
West of Ko Lanta, Ko Haa is a group of five uninhabited limestone outcrops. Topside, the islands are stunning and they do not disappoint below the water either, offering good diving opportunities for both beginners & advanced divers alike. They are famous for their visibility, calm conditions and spectacular underwater caverns.
The central area, known as the lagoon, is excellent for macro life, photography & training dives, while Island No. 1 offers boulders & wall diving with the chance to see larger marine life. Ko Haa Yai, the largest island, has two huge, connected underwater caverns which rise about 30m above sea-level inside the cave, allowing divers to surface inside. Just off from Ko Haa Yai is a small rocky outcrop that also has excellent diving.
