Koh Samet’s eastern coast boasts expansive white-sand beaches fringed with coral reefs, like Ao Prao beach, Ao Wai, Wong Duean, and Ao Cho beach. Due to their proximity to Bangkok and Rayong, these beaches welcome many travellers and ex-pats for fun-filled snorkelling trips, with equipment rented out for about THB 400. Koh Samet’s crystalline waters shelter stone hills, fish, crabs, spiny lobsters, clams, turtles and harmless sharks.
