Stephane and Deen were both amazing tourguides!! Probably the most friendliest, talkative and helpful tourguides that I ever had. The whole day was amazing and I would recommend this tour to everyone!!

Amazing experience. As a solo woman traveler, I felt very safe and welcomed by the crew. They were on time and made sure everybody had a great time. Definitely recommend it!

Such a choice on TripAdvisor - which Phi Phi island tour to choose. We were not disappointed with our choice. Why? These qualities from the onset of our trip gave use confidence in we had chosen the best company. • Communication • Punctuality • Organisation • knowledgeable • Safety Banja welcomed us all, explaining our day trip itinerary and sharing maps of the areas we were visiting. Banja and Stephane made every effort in making this trip a very safe, remarkable adventure. From hands on deck helping handing out chilled drinks to making it a special journey for anyone wanting to sit in the captains chair. Taking us away from the crowds and letting us enjoy secluded beaches for our amazing 4 course hot pic-nic lunch. Yes, this was very unexpected, pretty amazing lunch. Thai curry in paradise was not a joke. They had payed so much attention to detail and the ethos of minimalising the environmental impact by collecting litter brought in by the tide. We snorkelled in two different locations to optimise the amazing tropical fish and spectacular corals. Stephane and Banja always on hand to guide us to areas of interest. All achieved by their knowledge of the local environment. A super day trip with a very friendly crew. Some superb memories were captured by Stephane, who took it upon himself, to kindly photograph some of the highlights of us enjoying our day. Sending then to us afterwards. What a great gesture! Thoroughly enjoyed your company guys!

Fab trip with Panja as our guide, supported by Stephan. A great day out with nice relaxing schedule. Spectacular scenery and great snorkelling. Lunch on beautiful secluded beach was a highlight. Superb photos from Stephan to help remember our wonderful trip. Thanks

Amazing trip!!! Beautiful scenery, just the right amount of time at each place! Went snorkelling- so clear: coral, sea snake, stingray, fishes , eels. Amazing experience! Guides were awesome, Tuna and Marc! You the best team!

Amazing experience! Beautiful scenery, just the right amount of time at each location. Guides were fantastic and could not do enough! Tuna and Marc!!! Book this trip!

The most stunning scenery and snorkelling! Very comfortable boat and crazy, friendly guide Bella. Bella did everything she could to make it an amazing experience given it’s a very popular destination, including finding a quiet, beautiful beach for lunch.

Family and I had an awesome experience. Asked and Stephan were so energetic, informative and helpful throughout the excursion. Highly recommend!!

Let’s first start with saying how amazing our guides Bella, Mark and their team were. I have lived in Thailand for many years and this has been the best boat tour I have done. Every stop we made was perfectly timed so that we were one of very few groups at each location. The lunch was delicious and fantastic and to finish the whole day we had some amazing local fruit. If you’re looking for a boat tour book with these guys! Best in Krabi!!

Definitely worth checking out if you need to knock out the Phi Phi islands in a day. It was fast paced, and the lunch was simple. There weren't many opportunities to use restrooms on the tour except locations towards the beginning and the end. The best thing about the tour was our guide Stephane. Even though he was the Spanish guide, he did a lot to accommodate the English speakers. He was informative, caring, and energetic.

I did two tours with Thalassa; the Four Islands Tour and the Koh Phi Phi tour. I had a great time and would definitely recommend Thalassa as a tour provider! + The staff are really friendly and can't do enough for you. One couple were on their honey moon so the crew surprised them with drinks and fruit on the beach. Our tour leader - Tuna - was very attentive and ensured everyone knew the plan and was informed about the area and any sea creatures we saw. I had a great time. + Special shoutout to Apple who was really friendly and informative. In particular, most of the group was Spanish but I am an English speaker, so Apple ensured things were always translated for me. + On the Koh Phi Phi trip, we had lunch at the most beautiful island which was completely empty. It was bliss. Our tour leader explained that most tour groups will take you to the busy places because they get commission, but Thalassa don't. This was a really beautiful experience and having such an incredible place all to yourself was amazing. + The food was tasty and there was a wide selection of options to try. + Free drinks to stay hydrated located in a cooler on the boat, so they're ice cold. - The bioluminescent plankton wasn't quite what I was expecting and compared to what others told me they saw, this wasn't as special or jaw-dropping as I was expecting. This obviously isn't the tour company's fault though, just something to be aware of if you are expecting an amazing sight / are booking this tour for that specific reason. You have to move your hands around to actually see the plankton light up. - The tour leader on my second trip (Koh Phi Phi) did swim off a lot when we were snorkelling, which at times left me feeling a little stressed, I would have preferred for them to keep everyone together as a group. Overall, I paid a little extra to travel with these guys in the hopes that I could feel assured that I would have an enjoyable day and feel safe, rather than booking with some of the vendors in the booths on the street. I think it was worth it. You can trust you'll have a fun day with friendly crew members and some great experiences, photo ops and food! I would recommend booking with them

Great tour with excellent tour guides and staff. The snorkeling was super fun and you could see diverse fish. The speedboat was great and safe, and lunch was excellent. Do recommend this tour to anyone!

We had an incredible time doing the full day Phi Phi Islands tour with Thalassa! Our tour guide was Bella, who was amazing. She brought a ton of energy and excitement throughout the whole day. Bella is actually from Krabi and you can tell how excited and proud she is to show her home. Our tour started with a prompt pickup at our hotel. After a quick ride to the Nopparat Thara Pier, we boarded a speedboat and started our journey. The boat was comfortable and spacious enough - there were ~12-14 other people on the tour. Because we had many Spanish speakers on the tour we also had a second guide named Stephane join us. Stephane was also excellent- he spoke so many languages and was also very knowledgeable. Our first stop was Maya Bay, which is beautiful but a bit of a tourist trap. Bella offered to take some excellent photos of us, so definitely don't be shy to ask for photos! We then continued to a stop for snorkeling. We saw some really cool fish, small sharks (don't worry they aren't dangerous), and Stephane even pointed out a blue sea snake (again it was quite far away and never did it feel dangerous at any point). After, we visited another lagoon for a quick scenic swim. Then we went to a second snorkeling spot and worked our way onto the beach at Monkey Beach. The monkeys were fun to see, and as always you can observe people (not in our group) doing dumb things such as feeding the monkeys, etc., which I would advise against. Lastly, we ended with a picnic lunch at Bamboo beach - the food was nothing special but it was reasonable (Pad thai, Massaman chicken, etc.) and looked WAY better than the lunch I saw some other companies handing out. Overall, a 10/10 experience. The day didn't feel too long, and we felt taken care of the whole time. Bella and Stephane were awesome. Thank you so much!

Bella and Marc really made this tour a wonderful experience. They were very knowledgeable and invested to make sure everyone had a good experience. The weather and views were amazing on the day that we went. My favorite was Bamboo island which has the clearest water I’ve ever seen.

Well where do I start? Excellent day with two great guides Bella and Stephane, Very well organised with nothing too much trouble. The groups enjoyment is clearly the focus of the tour and their knowledge is first rate, taking us to a great place to see black tip sharks and the spot for lunch was just beautiful ( the food was great too). Thank you !

Great tour - we felt it was just the right duration and we spent enough time at each location. We had a very friendly team who provided us with water/soft drinks at many opportunities. Guides took photos of us at many locations m, better than relying on selfies. Our boat carried 11 people with enough space for approx 16 so not too full unlike some boats. Also the smaller boat meant we loaded/unloaded faster than big boats giving us more time.

Very disappointed in this tour. We paid extra to be at Maya beach early, but Tuna had arranged to go looking for sharks for 2 people , which they did first, leaving 7 of us to sit on the boat for an hour waiting. Maya beach was packed when we got there around 11. Tuna kept making excuses saying its always like this. Other than this it was a good trip but a long day. The food was surprisingly good. The communication was good regarding pick up. Just a shame the trip was tailored for Tuna and one other couple.

I was traveling as a solo traveler. Even at the very first beginning, Bella always made good mood and I never had the feeling of being left alone. So much entertainment and still relaxation at the same time at the most beautiful places is rarely available in just one package. Snorking and speedboating is absolutely suitable for everyone and any fear is unnecessary here. The lunch was also so good! And there is more than enough time for every stop as well. Marc and Bella were fantastic guides! I would book this tour again at any time!

Everything was great! They even had a car pick me up and I was 2.5 hrs away from the original pick up spot

Amazing tours! We went on 2 separate tours with this company (one private and one group). Our tour guide Tuna was the best! He was super nice and knew the best snorkeling spots. They also brought some great food for lunch and had a good mix of relaxing and snorkeling.
