Great day out from start to finish. All staff were engaging and friendly. Nothing was too much trouble. I would make sure you have breakfast before setting off as there wasn’t too much on offer by the time we got to the harbour. Lunch was delicious and plentiful. Snorkelling sites were busy but they are tourist spots after all.

A very good day trip, 3 snorkel locations, all fantastic with colourful fish. After an 80 minute trip you arrive for first snorkel for 45 mins and then you drive 5 minutes to next location for another 45 mins snorkel, then you travel 5 mins to lunch which was nice although the toilets weren’t the best so bring some tissues. Finally the last location you stay for 1 hour and 45 mins and can sunbake, chill or snorkel. So many fish and I recommend snorkelling again as this was probably the best location. It was very busy but we got ourselves a spot in the shade. The crew were friendly and boat ride was relatively smooth.

The tour guide was so helpful and nice. The boat ride was very choppy going there but that’s inevitable with a speedboat. Once we go to Koh Tao and Koh Nang Yuan, it was all worth it! The lunch was good too. I’ve been on tours where the lunch was not good so I really enjoyed this lunch!

Was a well organised and really fun day. Our booking actually got rescheduled due to high waves and unsafe weather conditions which we really appreciated as the boat trip wouldn’t have been great in awful weather. They picked us up from our hotel and transferred us to the meeting point where they provided a light breakfast and put us into coloured groups. The Koh Tao/Nang Yuan and the Angthong Marine Park tours take off from the same spot so it was very busy but the staff directed the crowd efficiently and all spoke great English. We had about 30 people in our speedboat for the 1.5 hour trip to Koh Tao and most people nodded off. Medication was offered prior to leaving the meeting point so I would recommend taking this as some people were seasick. The boat stopped at two Koh Tao snorkelling spots for 40 minute each before going to Koh Nang Yuan where we had 1 hour and 45 minutes to just chill out. If you’re interested in seeing the viewpoint at Koh Nang Yuan, the hike itself isn’t hard but there is a very long queue for photos at the top so do this as soon as you arrive. The buffet lunch provided was absolutely delicious and they also handed out bottles of water and soft drinks during the day. No towels supplied so you’ll need to bring your own which they made us aware of beforehand. Overall the day went exactly as advertised and we had no complaints.

The tour described does not correspond to the reality. During the day, we skipped at least two locations, including the Mango Bay without providing a clear explanation. It was only when the tourists asked whether we are going there, the boat captain said no, without giving any information. The smell of a fuel closer to the captain in the boat was quite strong, so be careful where you sit.

Dangerous. Miserable. -dozens of people had to be rescued from water or by boat which had no ladder, including me (strong swimmer) - they put a rope across 2 islands for us to hold onto -Had us go across water, no life jacket suggested, no inquiry to ask if we could swim - young child jumped in as her father being swept away in current - crazy thing, this went on for hours (tourists we crossing at direction of tour guides) DANGEROUS - 1st snorkeling spot, at least 500 participants all crammed in a sandy area about size of basketball court -snorkel area size of basketball court, not much to see except a few small fish IF YOU DON’T LIKE CROWDS, don’t go - Boat ride back, driver had no mercy in that there were big waves. We had been told it would be rough, but not told boat would rip back to pier - if you have a questionable back, you may find yourself in a worse situation. That’s it.

The boat trip is quite rough on the way back. You should sit inside the boat when it's rough for safety. Otherwise the trip was good. We saw a big turtle and also lots of fish. The hike on the first island can get busy and you have to wait a long time- I turned around and went snorkelling instead.
