Sunk in September 2023 near Mao Bay, the HTMS Hanhak Sattru (312) is one of Koh Tao’s newest wrecks.

You’ll swim along its 45m hull where trevally, groupers, snappers, and fusiliers gather in big schools. Nudibranchs and other macro life cling to the railings and outer decks, while the shaded areas attract batfish and moray eels sheltering among the structures.

It has already turned into a thriving wreck dive with plenty of marine life settling in.
