Lighthouse Pinnacle
A submerged granite pinnacle just off Lighthouse Bay on Koh Tao's north-east tip. It reportedly rises from about 25–30 m to within a few metres of the surface, built from stacked boulders with swim-throughs and ledges covered in soft corals and anemones. Yellowtail barracuda, fusiliers and trevally school around it, with giant groupers deeper down.
Tiefe: 5–30 m
