Koh Haa is a small group of islands in southern Thailand which are picture-postcard beautiful. Totally uninhabited and out in open sea, the islands remain pristine. The fact that the location is closed to the public for five months of the year makes Koh Haa an even more idyllic tropical island in paradise, due to its untouched natural beauty. The limestone cliffs jut out of the crystal-clear turquoise sea, and are home to several species of birds, including sea eagles. There are pristine sandy beaches which are ideal for picnics, sports and sunbathing. The shallow water reefs are perfect for snorkelling or swimming during a surface interval.
However, visitors at Koh Haa come to dive, and the experience here is among the very best in Thailand. There are dive sites for all levels of diver, from the newly certified to professionals. It’s even possible to learn to dive at Koh Haa. In addition to there being wonderful dive sites to suit everyone, they’re located very near to each other, as well. This means that experienced divers can jump in and enjoy a long or deep dive and then new or less experienced divers can do so too, all at the same time and within sight and picking up distance of the boat. There are about twelve dive sites at Koh Haa, dotted among and around the five main islands. They include exciting drop offs, underwater caves, sloping reefs, walls, & coral gardens. The marine life found at Koh Haa includes the best of all sizes and species, including regular sightings of Whale Sharks (Rhincodon typus) and Manta Rays (Manta alfredi). Small species of fish and invertebrates can be found by any diver with a good eye, and there are also marine reptiles, such as turtles and sea snakes.
Diving at Koh Haa is done in one of two ways. Day trip boats normally sail two hours from Koh Lanta, and offer two dives. Liveaboard trips can offer up to four dives per day, including a night dive, and they moor for the night in one of the sheltered bays. The liveaboard boats sail from Koh Lanta and Phuket, and usually visit the world-famous Hin Daeng & Hin Muang as part of the same cruise.
