Koh Surin Dive Sites - Koh Tachai South Reef

This dive runs along the south-eastern side of the island from the beach to the rocky tip of Tachai.

The reef is usually dived as a night dive due to it being a both shallow and somewhat protected area.


The reef begins with a shelf at 5m, which then descends down to 20m. Hard corals cover most of the area, which then changes into a sandy bottom. At the southern tip the site is deeper and can reach 30m.


Lionfish and many different types of morays can be found, and at night the reef is alive with shrimps, crabs and lobsters.
