Scuba Diving in Koh Tao Sites

Southwest Pinnacle

Southwest Pinnacle is located approximately 13 km from Koh Tao. The dive site is good to dive when the sea is calm as it's completely out in the open sea and has no protection from the ocean waves. But do take the opportunity if it presents itself as Southwest Pinnacle is one of the best dive sites near Koh Tao.

The pinnacle is a group of limestone rocks and big boulders that are submerged underwater and carpeted with pink and gold anemones hosting pink spinecheek anemonefish. Surrounding the rock formations are black corals and fans. Leopard sharks, marble groupers and blue-spotted sting rays are often found here on the sandy substrate.

Whale sharks can sometimes be spotted here from February to October. Apart from the big stars, Southwest is also popular with pelagic fish and their juveniles such as yellowtail barracuda, schooling reef fish such as yellow snapper and a few squid that have so far managed to evade the many squid boats of Koh Tao.
