Diving No Name Pinnacle in Koh Tao, Thailand

I dove No Name Pinnacle in August 2026 with Big Blue Diving, by boat out of Koh Tao, Thailand.

The barracuda school here was the best thing I saw in Thailand.

The pinnacle sits about 15 metres from the HTMS Suphairin wreck, close enough that the two get dived on a single tank.

That is how I dove it, so the log below covers both sites.

The Pinnacle

No Name Pinnacle is a submerged rock that tops out well below the surface, so the whole dive happens on the structure.

Koh Tao operators put the top at around 60 feet (18 m), dropping to roughly 100 feet (30 m) at the base.

The coral cover is healthier here than on the wreck next door, which makes sense given the Suphairin has only been down since 2023.

The Dive

You drop down the mooring line and the pinnacle appears underneath you.

Then you find the barracuda.

The school sat above the pinnacle for most of the dive and did not break up when we moved through it.

The average depth of 44 feet (13.4 m) against a 76 foot (23.2 m) max shows how much of this dive is spent up on the structure rather than down at the base.

Dive Conditions

Water temperature averaged 86°F (30°C).

The weather was poor the whole time I was on Koh Tao, and this day was no exception.
