A basic trip to 5 locations to do a bit of snorkelling. All was good overall. The staff were very nice and there were no issues. The boat was good enough we got a nice spot on the top desk (arrive early). The price was very reasonable I thought so 5 stars.

This day was absolutely amazing. They pick you up from your hotel and take you to the ferry port which you then get on the boat. They take you to 5 different snorkelling spots and nang yuan island. Helped us hike up and take photos. They were all so fun and helpful snorkling. They also took photos of everyone in the water and helped find turtles and sharks!! Would 100% book again and highly recommend anyone to do so!!!!!

Pick-up on time:-) The security was not good. They kind of counted how many people that was onboard, but I think they had little idea. We wrote our name and age on a pice of paper before we left. Those borrowing masks noted that as well. I think the only way they knew how many of us came back was when they counted the masks after we had returned home. An example of the lack of control. In a bay with rather big waves, a teenager jumped into the waster shouting “turtle”. 20-30 people including myself followed him. I am a good swimmer, but could not hold his speed as he had fins and I not. We swam far from the boat, and I turned back as I understood it would be harder to swim against the waves back. I didn’t want to get exhausted. No turtle found and I think everyone got back safely. Lunch was ok. Music too loud. Unfortunately the captain turned the boat because he said the waves on the north side would make us sick. Other boats went around the island as per agreement. On the positive side, we made five snorkelling stops and eventually saw turtles and had our photos. I think the company would benefit a lot from improving security

Snorkeling allow us to see lots of fish of various colors and shapes and jumping from boat allowed child-like fun for people like myself!

You were adequately provided with food and drink and had enough time to snorkel at all stops. Have seen baby sharks and two giant turtles. The guides were very nice. Underwater photos were also taken. The viewpoint on Nangyan Island was a bit crowded. But a little below you already had a fantastic view, so we did not have to climb to the top.

We spent an extraordinary day thanks to the escorts on the boat who were really all great! a real desire to share their knowledge of the place and we could see 3 beautiful turtles and baby sharks thanks to them. Sending photos in the evening is a real +. Thanks to them, we highly recommend this agency

Great chilled day out we had fantastic weather which helps I am sure Staff helpful and professional. Boat comfortable except if you have a bony backside take a towel or cushion to sit on! Food excellent free coffee and water on board. chance to buy beer or soft drinks on board. Take water shoes for first snorkelling spot as there is a big bank of coral to navigate and very sharp if you end up walking on it! Would definitely recommend

The trip was absolutely awesome! Super organized from front to back. On Ko Nang Yuan (first stop) we had about 1 hour 45 min stay, which was quite sufficient. The very nice guides show you the famous viewpoint and take great photos of you. Afterwards you have time to snorkel until you continue to Mango Bay and the other bays. At each bay you had about 30-40 minutes to snorkel, which was also completely sufficient. In between there was lunch, fruit and drinks. The very friendly guides took pictures with their good underwater camera all the time and made them available at the end (free!) via a WhatsApp group. The highlight were two sea turtles at Shark Bay and Freedom Beach, each with the guides making sure to keep a respectful distance from the animals and still manage to take fabulous shots. After more than 7 hours we arrived happy and with many wonderful memories at the port. If you wanted, you were driven back to your hotel for free (as well as picked up in the morning). I can recommend this trip to anyone, it was just beautiful!!
