A "secret" beach at the Similan Islands in Thailand. During the time when these beautiful islands are open to the public they are full of people. Travel tip: try to stay here overnight, so you can see the beauty of the island in the early morning when the tourists have not yet arrived #LifeAtExpedia

During a 4 day Scuba Diving Live-aboard trip at the Similan Islands, we had a chance to relax for a few hours in this beautiful bay with the stunning beach. The picture was taken just below a huge rock that resembles a sail. So the island is often referred to Sail Rock Island. #EndlessSummer
Hiked up to the viewpoint at Sail Rock on Similan Island. The water is so crystal clear turquoise it's unbelievable. There's a little snorkeling here but be careful, the shallows are very rocky and several people were sporting cuts on their feet afterwards.
This is island number 8 in the Similan national park, 70km from Khao Sok, North of Phuket. Great for diving, the Similan islands are some of the most beautiful in South East Asia. Speedboat ride can be bumpy and wet, it takes 90 minutes to reach this uninhabited paradise.
