We had the most wonderful experience on the Ang Thong Park trip. We couldnt recommend this more highly - 10/10. I contacted by whats app 3 months before arrival to ask questions because my daughter has a fear of vomiting and previously has been very anxious on boats. The company is owned by a British lady called Cara. She gave excellent advice and was very helpful, answering all questions promptly. Once we were happy with the weather conditions we booked, which was easy, with clear instructions. We were collected from our hotel promptly and given a very good briefing at the office by Cara. The crew - Jason, Captain Jeen, Ked, Clay, Phet and Midnight were fantastic. So professional and safety conscious , but also kind and funny. Jason gave a brief before each stop / activity. We did snorkelling first. The group of 12 was split into smaller groups, so my family of 2 adults, a 14 and 10 year old were with Jason. As a new and nervous smorkeller, i felt in good hands, with a life jacket and the ability to hold on to a life ring led by Jason. He showed us so many amazing corals and fish! So knowledgeable, and a genuine desire to seek us out all the rare and interesting features. We were in the water for around 45 mins then back on the boat where there were soft drinks, water and fruit. We headed to the most beautiful beach, which was empty. Maybe because it was New Years Day morning we were lucky. But the crew also plan to miss as many other boats as possible, which really makes this tour special. After a lovely lunch and some relaxation, we did a short hike to a stunning viewpoint. The crew carrying water bottles to the top and taking pictures regularly for us. Again, more fascinating stories and facts from Jason. Even washing sand off our feet before re-boarding the boat! Next was the stunning Emerald Lagoon and finally on to another beatiful spot to do kayaking. The crew even taking our phones to video us in the 2 kayaks as a family. If you are thinking of booking this trip, do not hesitate. It isnt the cheapest, but you 100% get what you pay for. My family has memories for life, and rated this as their best day ever! I was quite emotional afterwards in a good way! Thanks to Cara and the brilliant team, and we hope to be back again one day.

We had a phenomenal experience on our visit to Angthong National Park with 100 Degrees East. The whole team were highly professional, welcoming and helpful. The snorkelling with an experienced guide dedicated to our family was amazing. Our daughter was struggling with the mask and he was so patient, gentle and encouraging with her. We avoided all the crowds and enjoyed peace and beautiful views at every stop. The food was delicious and hospitality spot on. Massive thank you to the whole team!!

I am cross-posting a review I originally posted to Google here also, because a business this good deserves the recognition! I can't speak highly enough of this business - I'm so glad we booked with 100 Degrees East! I can very happily recommend them to both beginner and experienced snorkellers looking for an adventure from Koh Samui. We booked two tours with 100 Degrees East around Christmas 2025: - Small Group Tour to Ang Thong National Marine Park - Private Tour to Koh Tao The booking process was easy and well organised. I chatted with Cara on WhatsApp, she confirmed options very quickly the same day, and once we decided, she shared payment links for a 50% deposit. The day before each tour, Cara also messaged to let me know the pick up time from our hotel in Chaweng. The Ang Thong Marine Park tour was a great balance of time in and out of the water, and the small group size made it feel very personal. We saw much larger boats and crowds from a distance and were very glad we'd chosen a smaller operator. All snorkelling abilities were catered for, and the crew were professional, friendly and clearly very experienced. The speedboat itself was comfortable and well shaded, so no battling the sun on the trip out and back, or during the day! My husband unfortunately became very seasick on this tour - no one's fault, of course! - but the crew took such wonderful care of him. A crew member stayed close with him on the boat, provided medication, applied ice packs, and checked on him constantly. My husband recovered quickly thanks to their good care, and still came away with great memories of the day. We are very grateful that he was in such good hands, and know he wouldn't have had this same care with a larger tour group. The private Koh Tao tour was just myself and the crew, and I'm so glad I splashed out on the luxury of a private tour. I'm an experienced snorkeller, and my guide Dominik and I had an incredible day exploring three different sites, allowing me to set the pace in the water. We spent about three and a half hours in the water all up! Even though December is apparently considered one of the “worst” months for snorkelling, we still saw so much - including colourful Christmas Tree worms, vast amounts of healthy table coral, and the biggest green sea turtle I’ve ever seen. Not to mention a HUGE variety and number of fish! If you're a snorkeller visiting Samui and are trying to decide between a trip to Ang Thong Marine Park or Koh Tao, then you should definitely go with Koh Tao. The slightly longer journey time is well worth it, and it's easily one of the best places in the world I've snorkelled. Lunch on both tours was excellent: mild but flavourful vegetarian curries with two rice options, plus delicious fried chicken - and plenty of fresh water and soft drink to keep you hydrated. Thank you so much Cara, Jason, Dominik, Mr Pet and the rest of the 100 Degrees East crew for two unforgettable experiences! I wouldn't hesitate to book with this business again, and look forward to getting back out on the water with them next time I'm in Samui.

We were meeting up with friends and their extended family and booked this trip for us all to go for the day together. What an amazing day we had, from kids to grand parents, everyone was looked after and go to do as much or as little as they wanted. The organisation in advance was easy, and Cara and the team were brilliantly welcoming on the day. We couldn’t have asked for a more perfect day, snorkelling, swimming, kayaking and seeing the beautiful islands of the park. The team timed every stop perfectly so that we were not among the larger numbers of tourists coming off the bigger boats. We all agreed that the trip was excellent value for money for us as a group of 11 adults and 2 kids - definitely worth paying a wee bit more to have the boat for ourselves. A massive thank you to Cara and the amazing team on the boat for giving us an experience to remember.

Small group, max 12 was excellent. There was enough place for everyone in the boat and we were taking care of very well. Refreshments, fruits and food was very good. The timing was also perfect, no big groups at the same time. I was annoyed first because of viator did not tell us that we have to make a reservation directly from the operator because we were seven and there was some problem to combine our two separate reservation. However, the owner and Cara fixed this very smoothly without any problems. Thank you for that. We had a really nice day, the best staff at the boat and we couldn’t wish more. Much much better experience than few days before with the other operator. I highly recommend. If you are considering to do a diving/snorkeling trip in Koh Samui, choose 100 degrees east!

Our family had an amazing day out with the team from 100 degrees east tours, snorkeling diving and kayaking. They explained and showed us flora and fauna and gave talks on fish and coral, and we climbed to the emerald lagoon. . The team were professional when concentration was needed but friendly and relaxed at resting times. The food was lovely and suitable for all tastes. They joined in our family madness and made us so welcome. They were precise in every detail. Also leading up to the tour, Cara was liaising by WhatsApp so nothing was amiss. A company well worth paying a little more for the VIP treatment. We highly recommend them.

Outstanding!!! We had a great time and felt we were lucky to be able to see so much and experience wonderful activities. The 100 degrees east crew was extremely professional and courteous. They worked so hard all day and ensured our safety at all times! Plenty of food and water were provided as well as information on the sights and locations. Highly recommended!

The team at 100 Degrees East were incredible and the trip went beyond our expectations. Not only were the team fantastic but the trip was thoughtfully organised and small details like beach mats, towels and reusable bottles made the experience so much nicer. I couldn't recommend this trip more, do it!

Too good, saw some amazing spots, ate delicious food, did kaykaying and snorkeling with a small bunch of people and the most amazing staff, who well above and beyond for the tour, even took pictures from individual mobile phones from picturesque locations. A 10/10 experience, don’t miss this tour if you are in Koh Samui!
