Reviews: From Phi Phi: Sunrise & Beat The Crowds to Maya Bay by Speedboat
Guest User2024-10-07
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: Phi Phi Half Day Tour Speed Boat Tour
Guest User2024-08-13
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.★

Reviews: Snorkel in Koh Lanta, Thailand
Guest User2025-12-07
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!★

Guest User2025-12-27
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.
