All the details about your upcoming adventure in one place
A day trip from Koh Samui to Koh Tao and its tiny neighbor, Koh Nang Yuan, is the definitive experience for water lovers visiting the Gulf of Thailand. Koh Tao, known as 'Turtle Island,' offers some of the most vibrant marine biodiversity in the region, with crystal-clear visibility often exceeding 20 meters. These tours typically involve a 90-minute speedboat journey across the waves to reach the protected bays of Mango Bay or Hin Wong Bay. You'll spend your day drifting over coral gardens teeming with parrotfish, angelfish, and occasionally sea turtles, followed by a visit to the iconic Koh Nang Yuan. Here, you can hike to the world-famous viewpoint for a postcard-perfect photo of the white sandbar connecting the three islands, or simply relax in the shallow 'Japanese Gardens' snorkeling area. Whether you choose a high-energy speedboat group tour or a refined VIP small-group experience, this journey showcases the very best of Thailand's tropical beauty.

Real experiences from real travelers
The water at Koh Nang Yuan was like a swimming pool. Our guide from the speedboat tour was fantastic and pointed out a sea turtle at Mango Bay. Truly the highlight of our Samui holiday.
The islands are stunning, especially the viewpoint. It does get busy around noon, but the snorkeling sites the captain chose were relatively quiet. The lunch was surprisingly good!
We paid a bit more for the VIP small group (12 people) and it was so worth it. We left earlier than the big boats and had the snorkeling spots to ourselves for 20 minutes. Highly recommend!
I booked the 2-dive day trip as a certified diver. The equipment was well-maintained and Sail Rock was teeming with life. Professional dive masters and a very safe operation.
Everything was well-organized from the hotel pickup to the drop-off. The speedboat ride can be bumpy if there are waves, so take the motion sickness pill they offer at the pier!
I've snorkeled all over the world and Koh Tao's coral is in great shape. The visibility was easily 15 meters. Worth every penny.
My kids (10 and 12) loved the snorkeling. The guides were very patient and helped them with their masks. A long day but very rewarding.
The climb to the top of Koh Nang Yuan is steep but short. The view of the sandbar is exactly like the postcards. Wear good shoes, not just flip-flops!
