We also booked a 1 day snorkelling trip to Koh Nangyuan and Koh Tao in the Angthong National Marine Park - through Lomlahk. By Thai standards this is a very well organised day out. Pretty good value for money and very very easy. There are pros and cons in particular with Koh Nangyuan, but its our second time there and... More

I chose the speedboat trip which included transfer to/from pier, snorkeling, kayaking, lunch on one of the islands, climbing the steep stairs to see the view and a lake, free soft drinks. I booked this trip in an office runned by a nice Hindu man in Lamai, I think the boats belonged to Grand Sea Discovery.

Reviews were mixed for this but we said we would risk it, did the Kayaking, snorkeling tour, they are all different prices but we paid 1200 for it (advertised as 1850), it was the one in the big boat. It was full but i imagine at peak times it would be crowded it as fine for us though. Very annoying... More

We booked a 1 day snorkelling trip to Koh Nangyuan and Koh Tao in the Angthong National Marine Park - through Lomlahk. I give full marks to this tour operator - they were on time, efficient, organised, friendly and helpful. From pickup, registration, boat trip, snorkelling, lunch, return trip - everything was on time with no hick-ups. Would highly recommend... More

These are truly spectacular islands with endless photo opportunities and incredibly beautiful beaches. The trip from Koh Samui to Angthon took around 90mins due to strong cross winds, and whilst the water was rough the boat handled it well. I highly recommend that you take lots of sun block as the trip involves many hours in the sun, and the... More

Chose this tour over others as recommended by Lonely planet. The boat was older however less than 20 people. Staff great, included pickup and drop off at hotel. A variety of experiences. Kayaking wonderful. Day not rushed. Staff allowed time for relaxing, enjoying the experiences and plenty nof privacy on the various stopoffs. At the same time they were attentive... More

We took a speedboat tour and it was incredible - the speedboat also helps keep you cool in the thai heat as you get a nice breeze. The views are beautiful and you might even see dolphins. Trek up to the blue lagoon (up all the vertical stairs was hard work - so take water with you) but the view... More

Enjoyed the kayaking and snorkeling. Very busy tourist destination though, so just be prepared for that. Lots of other boats around. The food at the fisherman's village on one of the islands was very good!

We booked a day tour that included a transfer to the park on a big boat (not a speed boat), snorkeling and kayaking. It was nice, but nothing outstanding. It took us 1.5 hrs to get there on the boat. The food was served on the boat, which was nice, but other than that it was 1.5 hours of staring... More
