The Similan Islands, an archipelago of nine granite islands in the Andaman Sea, are world-renowned for their coral-white sandy beaches, crystal blue waters, and unique rock formations like the famous Sail Rock.

Real experiences from real travelers
We booked the private charter for our family of 6. It was expensive but absolutely worth it to set our own schedule and avoid the crowded boats. The guide took us to a quiet snorkeling spot away from the main groups. Exceptional service.
The water clarity is unreal. We did the premium speedboat tour. It was a long day starting from Phuket at 6 AM, but the breakfast at the pier and the lunch on the island were surprisingly good. The guides were very attentive to safety.
The islands are paradise, truly. However, even with the quota system, Donald Duck Bay was packed. The snorkeling stops were better as there was more space. Book the early bird options if you can.
Saw three turtles! The guides were helpful with my children who were snorkeling for the first time. The boat ride was bumpy, so take motion sickness pills if you need them.
Pickup from Patong was 5:45 AM. It's a long drive to the pier, then a long boat ride. But once you see the water, you forget the travel. Bring a waterproof bag and lots of sunscreen.
Very well organized tour. The pier facility had coffee and snacks. The speed catamaran was more stable than a normal speedboat. The beach at Island 4 is perfect for relaxing.
The islands are 5 stars, but the crossing was very rough today. The crew handled it well, but be warned if you get seasick easily. The lunch was just okay, but the scenery makes up for it.
The crew on the Wow Andaman boat was fantastic. Energetic, funny, and safety-conscious. They took photos for us and spotted cool fish. Highly recommend booking the premium option.

It is suitable for older children who are comfortable in the water. It is strictly NOT recommended for infants (under 1 year) or toddlers due to the bumpy speedboat ride.
