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.

Ko Tao was named by its first settlers after the island's turtle-like shape.[citation needed] Coincidentally, the island is an important breeding ground for hawksbill and green turtles. Development of tourism has negatively impacted the health of these grounds but a breeding programme organised in 2004 by the Royal Thai Navy and KT-DOC, a coalition of local scuba diving centres, has reintroduced hundreds of juvenile turtles to the island's ecosystem.
