Trip of a lifetime - all the highlights of Angthong Marine Park
16lianneg, October 2026
We cannot recommend 100 degrees east enough. They are more expensive than others, but it was very much worth it for the more personable service and flexibility of a smaller group.
For the Anthong Marine Park, even with a “full boat” of 12 people, there was more than enough space to feel comfortable with option to sit in the front, covered in the back or even the navigator’s chair with a super uninterrupted view. Although Angthong is particularly popular, the team were really good at trying to avoid the larger groups or at least timing our arrival at the popular lunch beach so we felt like we were experiencing the marine park without too many crowds. The team provided support for weaker swimmers on the snorkelling elements and were really good at pointing out particular fish and marine life.
All the staff were super attentive, ensuring that we had sufficient drinks and helping to take photos (particularly taking our underwater camera and getting great shots from a bit deeper as we didn’t want to dive down). The lunch provided was excellent, primarily vegetarian curries that weren’t overly spicy with some fried chicken for the meat-eaters. We appreciated being given a personal 5-10 minute warning prior to departure after lunch, in stark contrast to the other larger tour boats where staff yelled down the beach at the customers.
The 100 degrees east team and their tours really made our trip to Koh Samui. We would highly recommend them.

Outstanding experience

This trip was the highlight of our holiday. If shopping around, it can look like this is expensive but it is worth every penny and great value. The team think of every detail and look after you so well. All the guides were helpful, friendly and informative. We enjoyed the snorkelling, and felt very safe at all times. The emerald lagoon was beautiful and we appreciated the tour changing the iterinary to ensure we saw this at the best time. The guides will offer to take photos and videos, which for us all turned out amazing, great to capture the memories. Lunch on the beach was outstanding, good selection. Unlimited soft drinks, clean water, towels, electrolytes, fresh fruits, beach mats... all included!! Personal highlight the final stop where we saw wild monkeys!! Group size of 12 is ideal, not too crowded. Can't recommened this experience enough if you are on Koh Samui.

An incredible day out, jam packed with a variety of activities with enough space to relax and enjoy. The team at 100 degrees east were fantastic and the entire day from pick up to drop off was awesome. A must do when visiting Koh Samui.

What a day!

Amazing experience from the minute we left.
Although it was definitely a bit more expensive than other options available it’s definitely a case of you get what you pay for!
The entire process was made simple and effortless and the crew on the day were really friendly and super attentive.
Nothing was rushed, locations were spot on and the snorkelling and kayaking and hiking were all fantastic experiences. The food was delicious and plentiful
We couldn’t fault the day.
Shout out to Bastian, Tom and the entire crew!

100 Degrees East Dive Team also created a super experience here. We consciously chose a smaller number of participants and sustainability and were not disappointed.
Explanations, instructions, and guidance were top-notch! The service was really great. Many thanks to the crew and the support team and, of course, Cara!
