Amazing trip! Took us to so many beautiful beaches and places. Only thing that could be improved was the buffet lunch. Was luke warm and was eh.

Was a fun day. Monkey beach isn't really worth it, and because of high tide we ended up spending 2 hrs on bamboo beach which was a bit too much. But those are not really controllable factors. Overall, boat was good, locations were good. Being able to get to maya bay early was amazing! As was swimming in phi-ley lagoon and the two snorkeling spots.
Reviews: Snorkel in Koh Lanta, Thailand

My girlfriend and I booked a snorkeling course to Ko Bida and were simply blown away. The underwater world there is incredibly beautiful – we saw several sharks, clownfish, cuttlefish, and even pufferfish. A real highlight! We were accompanied by our diving instructor, Sofie, who dedicated a tremendous amount of time to us and explained everything calmly and clearly. Thanks to her, we felt safe and well cared for at all times. All in all, an unforgettable experience that we highly recommend to everyone!

We had a blast!! It was with the Sea Star group and was the perfect Phi Phi island tour- tons of stops, about 45 mins-1 hour each, they provided endless snacks, drinks, and lunch. The staff was extremely fun and friendly, it was definitely the highlight of our trip! Cannot go wrong with this day tour.

A truly amazing vacation! The staff is very caring and responsible towards their tourists (and others as well). I really enjoyed the diving; I would do it again many times. I also really liked how the instructors don't discriminate between "us" and "theirs"; they treat you with respect and concern. Even if you're struggling, the instructors will be understanding and patient. Overall, this tour and vacation were one of the best. I think our trip was worth it for the absolute thrill of relaxation and views.

We had a great time. They had great instructors and good quality equipment. Great trip for newbies. We got 3 meals, drinks, access to washrooms and ac. They also film and take photos of your dives and send you the files for free. Great value as it included hotel transfer as well.
