The 10 Best Scuba & Snorkeling in Koh Tao, Surat Thani Province

March 19, 2022 Weston Hennigan

Drifting serenely in the Gulf of Thailand, the palm-fringed island of Ko Tao takes its name from the abundant sea turtles that reside on its shores. White sand beaches sheltered by steep hills – some only accessible with four-wheel drive vehicles – and 300 days of sun per year invite long afternoons of lounging.
