Hi there,
I would suggest the island of Koh Tao. Koh Tao Thailand is easily the most relaxed and easygoing of these
islands; far fewer tourists make it here, and the island is surrounded by tranquil
resorts and welcoming eateries.
Diving in Koh Tao is the main tourist pull here, though there’s also plenty by way of other activities and natural attractions to keep you occupied for weeks on end.
