An exceptional tour! - This tour was one of the best moments of the trip and we did it accompanied by the Spanish guides Marc and Dan, and the local guide Boon (hope it is written like this). We visited all the islands of the tour, enjoying the beautiful views, the snacks, drinks and the exquisite food they prepared for us. The guides were always very attentive, even helping us take pictures. The sunset at Phra Nang Beach is second to none, but what surprised us most was being able to see so clearly the bioluminescent plankton during the night snorkeling. One pass! A fully recommended tour.

A great day - A perfect day with this Thalassa tour. Speedboat ride with a small group to visit the islands; stop at chicken island for lunch. Friendly and well prepared guides. The only flaw is the missed sunset by a whisker at Railey beach. Night snorkeling experience to see the exciting fluorescent plankton! Everything perfect!

Highly recommended experience on tour 4 Islands + sunset Railay + night snorkeling with Thalassa - We did the 4 Islands + Sunset Railay + Night Snorkel tour in Spanish with guides Stephan and Eki, and it was a very pleasant experience. The beaches we visited were great and the daytime snorkeling was really divine. At night, the area destined for swimming with bioluminescent plankton had a lot of dangerous jellyfish, so we decided to stay in the boat. Still, the guides were very attentive and took us buckets of water so we could appreciate how the plankton shone, which was a nice detail. I highly recommend booking the tours that Thalassa offers, as they work with small groups, are reliable and provide very careful care.

A magical experience on our Honeymoon – just the best! - Our experience with Thalassa during our honeymoon in Krabi was simply extraordinary. We took two tours: the 4 Islands tour and the Phi Phi tour, both of which exceeded our expectations completely. My only regret is that I did not have more days to do the third tour (James Bond), because the quality of this company is of another level. ​We want to make special mentions because the human team is what makes them unique: ​Dani: An endless thank you for your patience and attentions. Thanks to him, my wife managed to overcome her fear of the sea and had her first snorkeling experiences. It was a phenomenal moment that she will never forget; Dani was extremely attentive at all times, both on the first day and the second. ​Tuna: An incredibly charismatic guide who knows the sea like the back of his hand. Thanks to their experience, we were able to snorkel to see sharks and live the magical experience of bioluminescent plankton at night. It was a one-off! ​Jorge: You can see his vision and passion as Thalassa's boss. His way of planning routes is masterful; nothing is repetitive. Everything feels like a “tailor-made suit” designed every day to ensure that customers live exclusive experiences away from the crowds. ​We are very grateful and happy to have hired you for such a special trip. If you are in Krabi, look no further: Thalassa is the right choice to live the true magic of Thailand.
