Went with www.tourskohsamui.com after advice from here. Well worth it! Whomever you choose to do it with, you'll find yourself out there at the same time in the same places anyway! But it's worth getting a speedboat company. We went out (1hour) after our hotel pick up, stopped for snorkelling (45 mins), went off and stopped to climb to the... more

We went on a day trip with this company and we couldn't fault them! They visit all the usual places, snorkeling/scuba diving around the beautiful reefs of Sail Rock, the hidden lake etc, but they purposefully try to avoid other tourist trips at the same time. this meant that for lunch we had a beach to ourselves and could enjoy... more

We decided to go with the speed boat option, we happend to be on the trip that had the largest speed boat..lucky us!, Now when thay say light breakfast included they mean instant coffee and fruit, so don't expect anything else. (was fine with us, but there were some new yorkers who where a little disapointed) the tour should pick... more

We booked a trip to the Marine Park with "Grand Sea Discovery Co, Ltd." We chose them because they travel by speed boat making the journey just an hour from Samui. But they packed the boat with 27 people, and it was AWFUL!! 8 people had to sit in a cabin with absolutely no view whatsoever of the spectacular scenery.... more

I'll keep this review short and simple, if you are in the area, you MUST do this trip, bettre stlll stay over on the National Parl bungalows which I believe are only 400 baht a night, must boat companies will let you pick the next day's tour and to have this paradise area virtually to yourself is as good as... more

There are 2 ways of getting there, the "slow" boat with many travelers or the speed boat. Take the speed boat' save time and crowds and be able to reach some of the islands before the crowds do. Do not miss climbing to the hidden laguna A worth while day spent in Koh Samui. more

We traveled on a speedboat and sat up top as they had overbooked, but we had the best view with the wind in our faces. Stunning place, truly breathtaking! Kayaking was amazing as was lunch, snorkeling and the actual marine park sinkhole. You have to do this if you go to Samui!!!!! more

I loved my day out on the speedboat that www.tourskohsamui.com provides. They had three 225HP engines on the back of the boat and we moved through the water really quickly. We got to the islands in slightly less than one hour, rather than the two hours other companies take. We spent all day on the boat shuffling between the places... more

I brought my mom to this marine park for her bday and we had so much fun! We availed of one of the many tours available in our hotels. The brochure indicated that it was going to be a kayaking/snorkeling/sightseeing trip for around 975baht/person (Aug '08). However, I'm going to echo some of the reviews here that if you are... more
