“We visited plenty of sites around the island and saw lots of fish, which is what you want for a snorkel tour! We also saw turtles (sometimes they’re a bit hard to see as they only come up for air every 15 mins or so) but the tour guide was so helpful in pointing them out! Unfortunately didn’t see baby sharks but I think that’s okay, because they were quite scared from all the tourists crowding them. The tour guides work hard and are very social, though sometimes I felt uncomfortable and I saw one tour guide take a picture of me in my bikini without my consent, which made…”

The guide was very good at taking us to different spots where we could see interesting things. We got lucky cause there was only 4 of us on board which was amazing - almost private tour! But they never overcrowded the tour which makes it really worth the money. Much more comfortable and you can hit more spots / enjoy your time. I cannot recommend this option enough!”

We are very glad we paid a bit more for the "premium" boat-- it was super roomy, comfortable, and stylish. There were plenty of people snorkeling nearby from other boats and other companies but it didn't feel crazy busy, rushed, or chaotic. Shoutout to our guides Spy and Ben also. They took great care of us and had lots of good information and good vibes. Shout out also to our captain; I forgot his name, but he was an extremely skilled helmsman. The team adjusted plans due…”

★★★★★★★★★★4.6 · 135 reviews · 6 hours · from $28

Start late, skip the dawn alarm, and spend six hours exploring Koh Nangyuan and four Koh Tao bays. You get hotel pickup, a Thai buffet, gear, guides in English or Thai, and free underwater photos. Expect several 45-minute swims, a 250-baht adult park fee, sun exposure, and a full day on the water.

“It was a really fantastic day- great value for money. We saw some excellent sea life and the food and fruit on board was good. Just a tip- 90% of the people attending got incredibly sunburned (me included- my back is full of blisters). I would suggest wearing a t shirt in the water (maybe even leggings too as the backs of my legs got incredibly burnt). You are in the sun’s glare for around 4 hours, and cannot feel the extent of how badly you are burning. I applied sunscreen regularly but it washed off immediately in the water. Anyway, fantastic trip, well organised and brilliant value for money.”
