Discover the most beautiful islands of the Andaman Sea
Join us for an unforgettable one-day adventure to the Similan Islands, a true jewel of the Andaman Sea. Renowned for their crystal-clear waters, stunning coral reefs, and powdery white sand beaches, these islands are part of a national park that is open to visitors only from mid-October to mid-May, in order to protect their unique ecosystem.
This excursion from Khao Lak is ideal for nature lovers, snorkelers, and anyone seeking a postcard-perfect tropical escape.
What makes the Similan Islands special?
The Similan Islands are a group of 11 islands, each with their own character. You’ll visit some of the most beautiful and accessible ones:
- Island No. 8 (Ko Similan): Home to the famous “Sail Rock” viewpoint, where you can climb for a panoramic view over the turquoise waters and boulder-strewn coast.
- Island No. 9 (Ko Ba Ngu): Known for its vibrant underwater life and colorful corals – perfect for snorkeling!
- Island No. 7 (Ko Payu): Another top snorkeling site with excellent visibility and a chance to see clownfish, parrotfish, and more.

The Similan Islands are very different from the beaches around Khao Lak. Clear water, white sand and beautiful places to swim. Some beaches were busy, but it did not stop us from enjoying the day.

We mainly chose this excursion for the snorkeling and were not disappointed. There were several different spots during the day and beautiful beaches between swims. The speedboat ride can be a little bumpy but remains manageable.

An early start, but necessary to make the most of the day. The islands are beautiful and the water is very clear. We made several snorkeling stops with plenty of fish to see. Everything was efficiently organized from start to finish.
