Phi Phi Scuba Diving Sites

Hin Dot

'Chimney Rock' is located just outside Tonsai Bay to the south of Phi Phi Don and is therefore only dived by Phi Phi diving boats and liveaboards.

When not exposed to strong currents, Hin Dot forms a great multilevel dive. There are 3 chimneys aligned close together in a north-south direction, the deepest rising only to 16 metres below the surface. The main pinnacle has 3 ledges at 3 metres, 12 and 15 metres, then drops down to 30 metres. This provides an ever-changing underwater scenery as you slowly ascend, spiralling ever upwards.

There is an amazing amount of sea life concentrated in such a small area. Huge schools of yellow fusiliers circle around, and larger fish such as trevally and barracudas are common, feeding on the smaller baitfish. The show will easily keep you occupied for an hour.

Purple and orange soft corals, tube corals and hard corals cover the pinnacles, with christmas tree and tube worms. Inside the rocky crags are all manner of shrimps, small lobsters and crabs; and nubibranchs are easy to spot here. The deeper walls are embedded with zigzag clams, giant clams and oysters.

The sea floor here often has leopard sharks, and it is recommended to carry a safety balloon as the entry and exit point is in the middle of Tonsai Bay and exposed to boat traffic.
