Highlights
  • Mae Haad Pier - Start the trip with a pickup service from your hotel lobby and get driven to Mae Haad Pier where you will meet the crew of Sangthong Tours.
  • Koh Tao - After a quick health check, board the modified fishing cutter and chug to the first snorkel spot at Koh Nangyuan off Koh Tao’s northwest coast.
  • Nang Yuan Island - Walk on the iconic beach that links the group of three islands of Koh Nangyuan together, and climb up to the viewpoint on the peak of the highest of the three islands. There are a few separate swimming areas with tropical fish, including Japanese Garden as the best snorkeling spot and others where you can just chill out and relax.
  • Mango Bay - Head over to Mango Bay while enjoying a Thai style lunch on board. The bay is named after many mango trees that once grew on this part of Koh Tao in abundance. The magnificent Mango Bay shines with turquoise green and beautiful waters that are full of marine life. Due to shallows off the beach and the sandy seafloor that gives the water a beautiful turquoise green hue, Mango Bay is a go-to destination for snorkel activities.
  • Hin Wong Bay - Continue to Hin Wong Bay located on the east coast of Koh Tao surrounded by big boulders. There are several underwater pinnacles covered in fertile coral, anemones and many kinds of fish that can be seen here. The water here is incredibly clear and you may be lucky enough to see great schools of sardines being chased by hungry trevally in water less than a metre deep.
  • Aow Leuk Bay - The next stop is at Aow Luek which is named for its deep, concave shape as well as the depth of the water which makes it good for snorkeling even at very low tide. Expect a stunning scenery with white sandy beach and water varying shades of blue, and Shark Island in the background.
  • Shark Bay - Before returning to the pier, make a stop at Shark Bay where you can swim alongside the many blacktip reef sharks or the sea turtles that come there each day.
  • Sangthong Tours - We are a locally based tour company on Koh Tao specialized in snorkeling and fishing trips. Book with us and we will show you the beauty of Koh Tao and Nangyuan Island on a group or private tour. Visit Mango Bay, Ao Hin Wong, Aow Leuk and Shark Bay on our modified fish cutter and walk on the iconic beach that links the group of three islands of Nangyuan, which is also the perfect snorkeling spot with turquoise green and beautiful waters.

Excellent snorkel day - Excellent day. We had an amazing time snorkelling 5 areas, seeing loads of coulourful fish and a turtle. Lunch was yummy and lots of fresh fruit available. Recommend you do the hike to the view point first as this gets a queue.

Most wonderful snorkeling trip - It was an amazing snorkeling trip with professional guides. As we were a bit earlier than the other snorkeling tours the spots were almost empty. We saw baby sharks and big turtles. We got some beautiful pictures and had a really great time. Thank you Pon and Team!!!

Good times - Great tour with informative staff. Delicious lunch! Rough seas were tough on some people, I would listen to guide and wear life jackets if you feel!

Good experience but would book elsewhere - Three stars because I can’t dispute that I thoroughly enjoyed the snorkelling, we didn’t see much - one turtle, a couple beautiful fish and coral. The first stop at Koh Nangyuan which you have to pay 250 baht to enter was by far the best part where we saw the most fish and after that it got a little disappointing. However I understand what you see on the day can’t be certified so that’s okay. My reason for the three stars is as much as I would recommend snorkelling tours i wouldn’t recommend booking through this tour company. They forgot to pick me up from my accommodation and after an hour I was collected and taken to the boat where everyone was waiting. There was a lovely guy working on the boat but he did not speak English the the other staff weren’t particularly friendly.

A little disappointed tour - Firt we started on the Island Koh NangYuan. It was a nice view. We stayed there for 2 hours. (To long id you ask me). To bad that we couldn't snorkling. The lunch and food on the boot was fine. Unfortunately there where big waves so we couldn't go arround the island, so we made the second stop and a alternative third stop. Then the boat broke. So the made an extra stop, but under water was nothing to see. They arranged a taxi boot and a taxi to our hotel. They fixed that very well. Unfortunately my conclusion is that the snorkling was disappointed and that's why we wanted to do the tour.
