The trip was amazing, and the itinerary so professionally worked out..so special avoiding the tourists… The crew were all great, would definitely recommend 100 Degrees East for a memorable day out… we even saw Whales!! How special

We’ve done many organised tourist activities over the years and this company has to be one of the best. Brilliant crew , well organized, very comfortable boat, nice food and best of all great snorkeling / kayaking sites. Did I mention the amazing marine life , and even a turtle and many whales in a feeding frenzy!

From initial contact with Cara through to getting back on the private Minbus to go home, the who experience was as professional as it comes. We we're a family if 3, two certified Divers and our 17 year old on his first try a dive. When we arrived at the office on dive day everything was set out for us, paper work to sign, your own personal sterilised water bottles and a nice smiling welcome from Cara, the dive team and the boat Crew. Our Instructor was 'Kay', with her wealth of experience and knowledge she made the day so easy for us. We had two dives in Koh Tao with lunch (OUTSTANDING), and snorkeling in-between, we even got to go ashore on the island for a mini look around. Boat crew were all outstanding and the tour guide and Dive master 'Meow' explained everything perfectly. What more can I say, great team, professional from start to finish. I'm a great believer in the old saying ' it's the little things that count', and you certainly did. 100% recommended. Great day. Thank you team.

The small group experience was worth the extra cost. The equipment was well maintained and high quality. The mask was the clearest and most leak-free I have ever used. They even had a –2 Rx mask for my husband who wears glasses. The beach lunch was delicious. The crew helped graciously with every step of the day. It was a highly professionally run company. We saw a lot of coral and a nice variety of fish species. Unfortunately the reef colors are “washed out” due to climate change and if this is the best snorkeling spot in Thailand the oceans are doomed. Sad to see local fishermen fishing out the tiny fish in the snorkel habitat. None of this is the fault of the tour - just some editorializing about the dire future of humanity as we know it. Snorkel now before there’s nothing left to see.

Had a fantastic time today on the Koh Tao Snorkelling trip with One Hundred Degrees East. Staff very friendly and attentive, couldn't do enough for us, and made trip so much fun. Had two snorkeling stops of about 1 hour each over a coral reef with many different types of fish and wildlife. Including in the second place chance to see green turtles in their natural habitat. Day also included refreshments on request and a lovely Thai lunch which we ate on a secluded beach. All in all, it was a great day and fully worth the price paid.

I went on a snorkeling trip to Koh Tao with The 100 degree east team in January 2025. The day itself was excellent, and the snorkeling was fab. From start to finish the team at 100 degree east were friendly, cheerful, informative and efficient. You can take cheaper trips on more crowded boats to Koh Tao. However if you want a more personal service with a professional team, then spend the extra and go with these guys.

My husband and I booked this via Viator, having read the Tripadvisor reviews. It is a must-do! If we had been asked to put together a plan for a perfect day snorkelling, our day with 100 Degrees East was it from start to finish. Great communication from Cara prior to the day so we knew exactly what to expect, what to bring with us and times we would be picked up and dropped off. Before getting onto the boat, we were warmly welcomed at the centre and made to feel that the day really was geared to making sure we had the best time. Mix of people had signed up - 1 family, couples, friends and some single travellers - and we were all really well looked after. No one was left out. The crew were fabulous. My husband and I had Tom as a guide in the water, who was lovely, patient and very knowledgeable. He pointed out all sorts of sea-life, that we would never have noticed on our own. The team set up everything for us for lunch - it was delicious and probably the best Thai food we had on Koh Samui!! One of the things that sealed the day and showed the sort of company 100 Degrees East are was over lunch - the crew ate what we ate and chatted with us all. It felt like we were with a group of friends. The serious side - everyone’s health and safety was treated with utmost importance and we felt comfortable and looked after at all times. A really friendly, relaxed, fun and fascinating day. Worth every penny. We were just sorry that we hadn’t booked one of the other tours - but we will do next time!!

The Crew at 100 Degrees East are second to none. Not your typical tourist experience. Cara and her crew really care about you having the best experience. We joined them last minute for a snorkeling/scuba trip to Koh Tao. We personally were not Scuba Diving, but the instructor was great. All the crew were great. Very personable and knowledgeable of the waters around the islands. It had rained off and on before our trip, so in some places the algae was stirred up making visibility a bit tricky. We abandoned some sites to find better water. It was amazing, able to swim with two sea turtles and many many colorful fish. Our snorkel guide Tom was amazing. Can’t really say enough. And then to top it off, we get back and the crew was disappointed in our trip so much so they returned some of our money!! Who does that? Cara and her crew do. If your on Koh Samui/Bo Phut area check them out. Worth every smile.

Yes, the reviews are accurate. What an amazing experience we had with the 100 Degrees East team. From the first email exchange I had with Cara, it was such a professional and well organised experience. Our trip was actually delayed due to the weather but Cara was in contact to let us know and I definitely appreciated waiting a few days until the weather improved to give us a better experience. We were picked up on time from our hotel, had a quick briefing at the centre and headed out on the speedboat to the first dive site in Koh Tao. My wife was diving, I was snorkelling, and we both had a great small group experience. We had a fantastic lunch and then another dive/snorkel followed by a final one at the end of the day where we swam with turtles. Honestly this was one of the best trips I’ve been on, staff and crew were fantastic and I would 100% recommend them. We also did the Angthong trip which was great too, see my other review!

We had a fantastic day with the Kho Tao tour, dive sites were beautiful, the boat was very comfortable and the diving equipment was perfect. Above all, the crew was amazingly nice, smily and helpful. Ben was fun and professional, he was a good instructor for those who dived for the first time. Definitely recommending this company for a diving trip in Kho Tao. Charles and Family 😊

We had the absolute best experience with the 100 Degree East Dive team. It was our first time snorkeling in the seas and we were guided exceptionally well through everything. The boat was in great shape and clean, the equipment they provided was very good, we had two senior team members guide us in the sea plus others on deck. You just have to show up at your hotel lobby with your swimsuit and they take care of the rest. Boat ride is one and half hour each way. Fresh fruits and lots of cold drinks throughout plus towels. We saw plenty of fish and coral and a giant turtle! We snorkelled at a total of three sites around Ko Thao and anchored off Mango Bay where the crew set up lunch- a whole spread of veggie curries, rice and fried chicken. The vegetarian food was on our account, since they ask us for food preferences before the trip and generously followed through with our request. There was plenty of space on the boat with 9 people plus crew members with 7 of us snorkeling and 2 diving. Each couple had their own guide in the waters. They even took our photos and took care of us in all possible ways. A big thanks to the team. Weather was partially cloudy which saved us from the sun a bit. Would highly recommend this trip and company to everyone considering snorkeling or diving. Thank you for the memorable experience!

Absolutely fantastic day. I done snorkeling whilst my husband completed his 1st scuba dive with Ben who was fantastic. Great tour, very professional. Would highly recommend 👌

Its hard to put in to words how well this tour is run. They have thought about everything in meticulous detail to make sure that everyone has an amazing time. I’d specifically like to mention the fact that there were 7 staff for a tour of 12 people - lived up to the VIP name! I can not recommend this tour enough!

A small family run business, with excellent staff, organisation, and kind, caring individuals, who genuinely want you to have a great time. I wish TripAdvisor could rate them as 6*, as this trip exceeded all my expectations - best tour I have been on. I want to give the biggest thanks to Cara (for being patient with my endless Whatsapp messages) and Ben (dive instructor) for looking after me while diving, especially when I occasionally bumped into him not knowing which direction I was swimming or going up and down on my buoyancy. Actually all the team were incredible, from boat crew, to the transfer and in between. I was a bit apprehensive paying the extra for this tour, but if you take anything from my review, go with this company. You will not be dissapointed in the slightest for the price. For what you get, it’s a bargain. I did 2 discover scuba diving with this company and it was perfect. Was picked up by one of the team and taken to their base, greeted by one of the owners (Cara) who I’d been communicated and booked through Whatsapp. Was briefed by Ben (dive instructor) and then on our way on the speedboat to spots avoiding a lot of the tourists (they go out of their way to find the best spots). This team really goes above and beyond, with a max of 12 customers on board (14 if children), soft drinks throughout, water, fruit, a delicious cooked meal set-up at a beautiful beach (Mango Bay)… delicious! A cold shower after scuba (really woke me up!). Ben (dive instructor) was super friendly, easy to chat to, and helpful. I was lucky enough to have 1-1 instruction on the tour by him, and really gave me the confidence to dive (last time did an intro dive 10+years in Australia). He made sure to make me aware of the rare species we saw, chatted afterwards to make sure I enjoyed, and felt like we were a team when diving! Really keen on doing my PADI license after this - really do commend him on his ability as an instructor - thanks Ben!! Could not fault the company, everything was timed perfectly, well-run, and it’s the small things that show they all care - crew asking if you wanted a drink throughout, chatting to us, one of the guides went to take a picture of a turtle for me, as I struggled to freedive. And the team (and the owners) were waiting for us on the beach as we were coming back. You read many reviews that are 5 stars, but this company exceeds that massively, and you would regret not going with them. Thank you to all of you, and if I return to Samui again, I will be at the front of the queue to book again :-)

A truly amazing experience from start to finish; we had an incredible time thanks to Roon, Cara and the rest of the 100 Degrees team. From our initial WhatsApp correspondence with Cara to the very warm welcome on the morning of our trip and then the trip itself; everything was faultless. The boat crew were ace and our guide (the legend himself, Mr Tom) was super knowledgable and a joy to be around. The delicious home cooked food, the clever timings to avoid any crowds (thanks to Roon's years of experience) and the mind blowing beauty of Koh Tao made this a BIG highlight of our holiday!!! Cannot recommend these lovely humans enough (in fact we liked them so much, we actually booked two trips!!!) Mike, Joss, Max and Manny x
