Our boat tour was fantastic and the crew was amazing! A great balance of locations and just enough time to enjoy at each stop.

Firstly, do not rely on their "breakfast" (dry bread & jams), have breakfast before you leave. The majority of the time was spent inside the speedboat, where you can't see much apart from the other guests, and extremely cramped - overbooked? 10 less people would have been great. The 5 different stops in Ang Thong national marine park were good, only the first one for snorkelling, lunch was good, guide/leader was good. The steps to the viewpoint are extremely steep, not for the fainthearted. For this excursion you need to be physically fit. Oh, and bring a toilet roll for the toilets, there is none 🚻 Also mossie spray for the stops 🦟 Overall, wouldn't recommend this tour for the money

Hotel pick up on time towards the harbour . Nice day tour with beautiful nature sighting. However the snorkel stop is very crowded and lacks safety measurements. We arrived with 10 boats at the stop. Around 400 persons in a small snorkel zone . Boats reversing while people were snorkelling around. Our crew was courteous and gave good guidelines for the stops. I would suggest to book a more private tour.

All beautiful, only it was not well signposted in advance the difficulty in climbing to 500 meters high with improvised stairs to enjoy the beauty of the view point on the islets of the park. Everything else great as organization and friendliness of the staff as well as the beauties we could enjoy.

The tour is very worthwhile, especially if you go to the viewpoints. The problem is that it takes a long time to access them because they are very hard climbs and does not give time to enjoy the spectacular beaches of the two islands that are visited. The food is good.

I cannot recommend enough this day out. From start to finish we were looked after so well by Singha and his crew. I’d never snorkelled before and the whole experience was truly amazing at the marine park. Plenty of opportunities to swim and hike at the stops. A fabulous lunch was provided. Such a wonderful, memorable day. Thank you so much Insea

Our Tour guide Sunshine 🌞 was very informative, and made our day very special, he took time to explain everything very clearly to all the different groups.

There are lots of trips and tour companies to choose from, we ended up selecting InSea, and booked it by click2gothailand.com. The trip was well organised, friendly and fun crew on the boat, the crew were on hand to take photos at each location even at the highest view points and didn't just wait on the boat. There were about 30 people on the speedboat with sufficient space. The included lunch on the fisherman's island was also better than I expected. Overall recommended and a really good day out.

We began with a stop for a bit of snorkling and then went on to the national park. The climb to the summit of the island was rather rough but there were plenty of rest points. The view was definitely worth it though. We also wanted to do some kayaking so had to be reasonably quick to get up and down again with enough time for that. The third stop at the lagoon was equally as beautiful with a much shorter climb. Finally we stopped for a very nice buffet lunch before heading back to samui. All in all it was a very enjoyable day with enough time at each stop to do what we wanted to. Our guide was very informative and explained everything in detail. Would definitely recommend the trip.

Booking this trip with the speedboat was the best decision! Our crew of boat #6 was great. Other local companies are using longtail boat, there is NO shade, people sitting on wooden seat with life jackets on at all times. When we saw it we almost cried. Go with a speed boat!!! Our boat had ice cold drinks. When we were getting on the boat at the islands and the loading deck was so hot we couldn’t stand on our feet the crew was splashing cool water on our feet 😀
