A perfect day, jam packed and all timed so well. Not too much of anyone thing - snorkeling kayaking chilling - and great amenities throughout. Top notch outfit for sure.

This was such a great way to visit Ang Thong! From pick-up to drop-off, it was very well run. I came on this tour solo and everyone was very welcoming. Roon was an awesome tour leader, but the whole staff was great! They timed everything very well, and we were able to avoid crowds the majority of the day! The group size was fantastic and the food/drinks were readily available and delicious. I highly recommend this tour!

Spent time researching a reputable company four our tour, and we're not disappointed. The little touches such as being provid a metal water bottle for the day that was refilled whenever required, and much more environmental friendly than the countless plastic water bottles used on other day trips was great. When snorkelling, we split into groups of four, with a guide each to point out some of the marine life. We had fins, which made a big difference. And back on the boat there was a booklet of the common fish, so you could look up what you had just seen. We stopped for dinner at a beautiful spot, where the guides gave us beach mats to relax on, while they set up a tasty buffet lunch. Then we went Kayaking around the karst limestone rocks. The guides took our phones so they could get some great action shots of each kayak and it's participants. The day ended with a hike up to the viewpoint of the Emerald lake. The guides carried out water bottles up, so we could focus on the steep climb. This was timed so that we did not need to battle with other tour groups There was some bad weather rolling in, so unfortunately, did not make it to see any of the Dusky Monkeys, which was a little disappointing. But we appreciated the captain putting our safety and comfort first for the journey back. On the day, we witnessed a few other big tours who were feeding the fish at the snorkelling points, travellers stepping on the coral and generally being hardened from one spot to the next. 100 Degrees East provided a semi private tour, which meant much more experience from the tour guides and a big emphasis on the environmental aspects of the day.

This was a full day excursion as noted. First snorkeling, then onward to another island location for lunch, leisure beaching & some relaxation time on the secluded beach followed by kayaking. Lastly, a quick boat ride to Emerald Lagoon, where we had to make steep climbs up quite a few stairways for a glorious view of Emerald Lagoon. My husband moaned and groaned throughout the whole climb but in the end, it was worth it! I wouldn’t recommend the climb for anyone that is not as fit and on the heavier side, just saying it would be an arduous task. Now, if you’re young and springy, have at it! Snorkeling was our favorite as we got to see lots of marine life. There were about 12-14 of us and we were separated into groups of 4 with a guide. Our guide Star, was amazing! and as a first time snorkeler, I took advantage of the assistance from him who had a small float for people like me needing to build up snorkeling confidence. I grabbed onto the float rope attached and Star would drag it to all the cool spots while I stuck my head down to see the various marine life. Only during the last 10 minutes did I find my confidence/courage to let go and wow to my amazement, I didn’t float away. Furthermore, there were plenty of drinks on board, a decent lunch was provided and on the boat, fruits were passed out after each activity. Oh and almost forgot to mention the crew even took pictures for us when photo opportunities arose. Overall, the crew members were absolutely amazing! Super attentive to everyone’s needs, made sure we were hydrated, looked after our belongings at each location and provided great service. In our opinion, this excursion was worth the price as we felt cared for and looked after during the trip. Thank you to the 100 Mile Marine Team for a memorable experience!
