Also known as 'Koh Haa Nuea'. Located on the most northern island of this cluster of five limestone gems. 'Haa' in Thai, means five and 'Koh' in Thai means island - hence Koh Haa. The island is encircled by coral reefs comprised of a mixture of healthy hard and soft corals. Koh Haa is seldom dived due to its remoteness, so is still in pristine condition. Speedboat trips from Koh Phi Phi tend to bypass Koh Haa and head further south to Hin Daeng and Muang. The visibility around Koh Haa often reaches in excess of 40 metres. The chimney is a fantastic piece of natural sub-aqua architecture, that leaves divers wanting to go back again and again. The entrance is at about 17 metres and leads in past golden sea fans and soft corals, before opening out into a vertical chimney structure that can be ascended and exited via two different holes at about 5 metres. |
