We enjoyed the tour a lot! It was easy paced but we still got to see so much. Even though it is jellyfish season and could not swim with plankton, our tour team found a way to show the plankton to us. Beautiful! I do recommend.

Bass was the most lovely tour guide. He was extremely informative, telling us about the many islands of Thailand, the Thai people, and caves and beaches we visited. He also took photos and videos of us and the sights the whole time. This tour was 10/10. I recommend eating a big lunch before and bringing ample snacks. For the plankton, you will do best in the water but I was too nervous. Still, Bass showed us the plankton in a bucket and it was a cool phenomenon to see. I highly recommend booking a private tour with Bass.

Brilliant day trip, made even better by our guide Nut. Picked up and dropped off at our hotel. Nut provided us with water and fruits on the boat, mats for using on the beach so we didn’t have to use our towels and helped us pick the best spot to take pictures and was happy to get pictures of us as a family. She took us to the free toilets so we didn’t have to pay, recommended places to eat and advised us on times for sunset. She picked the perfect spot for plankton swimming which was an incredible experience. Would highly recommend this trip.

This trip was fantastic, we were lucky enough to be the only ones who booked so had a private tour. The speed boat was exciting, Railay beach at sunset was amazing and the bioluminescent plankton was the best part of a fantastic day. Our guide Jess was very welcoming and knowledgeable. Would definitely recommend this trip.

It was wonderful! We were only a group of 4 pax and it was nice. The guide Ef was wonderful and surely knowledgable but most of the time she gave us time to ourselves and roam and do our thing on the stop over places. The plankton experience was the most wonderful.

The trip was amazing, the guide and the crew were very kind. We weren’t able to see the plancton because it started to rain and we had to come back to pier.

Our guide sandy was great and very knowledgeable. The trip itself is good if you want something that gets rid of all the hassle of having to sort everything out yourself. Highly recommend the scramble up to bat cave if you go. Swimming with the plankton was by far the highlight of the trip!

Absolutely outstanding! Great day, amazing place, ideal tour, free time to do your own thing relax at beach, and swimming at night under blanket of stars with bioluminescence was the most unreal experience of my life, the guides were so happy, cool and chilled, fab tour.

We were only 3 people in the tour so all experience was for ourself. We saw a flock of bats at sunset, leaf monkeys, planktons at night. They allowed us plenty of free time as well for the beach.
