About this place

Part of the Hat Chao Mai National Marine Park, Koh Haa is accessible via day trips from Koh Lanta or liveaboards from Phuket. The famous Cathedral Cave at Koh Haa Yai features an air pocket where divers can surface inside the cave - a truly magical experience. Visit during the dry season (November-April) for best conditions, and bring an underwater flashlight for cave exploration.
