It was pretty good. I took my 9-year-old granddaughter there, and she had a wonderful time! The service was warm and friendly, they were responsible for safety, and they provided pick-up and drop-off service – great!

So much fun! I want to go again, maybe try a full-day trip. The boat driver was skilled and experienced, even though it rained the day before. They were attentive and gave great advice. It was really private, and we got to snorkel and see the fish – it was great!
Reviews: MuayThai Class for Beginners
Guest User2026-02-19
I went to a Muay Thai for Beginners class and absolutely loved it. The instructors were very professional and clearly took their job seriously. We started with a proper warm-up and stretching, and we also finished the session with stretching. There were always 2–3 trainers coming around to check on us and give individual guidance. I think Muay Thai is definitely a must-do activity when you come to Thailand. Since it’s the national sport, practicing it here also allows you to experience and understand Thai culture from the inside.

The tour guides and their energy made this trip worthwhile. Although unfortunately there were no dolphins sighting, the trip was exhilarating and enjoyable. The guides and staff really made this experience very special, and I commend them for being such a group of people with great personalities. All locations were beautiful, and they truly did their utmost to try and locate the pink dolphins. I will be back, and I will try again with this tour group!
