Must do - fantastic snorkeling in clear warm water and a beautiful beach for lunch but be prepared for a fair amount of time travelling on the speedboat.

Great experience - A great trip with very good care, before I chose which agency we would go with to Koh Rok and Koh Haa, I did a lot of research and it turned out to be very accurate, we were the first at all the snorkeling spots, a great, large and clean motorboat with a toilet and, above all, great care , the guide spoke English well, he informed what to watch out for in the water, before the group entered, the water was checked by the organizing team, I highly recommend it, when I saw other boats leaving for the same place, I was glad that my choice was Opal Travel

Crystal clear water and one of the best places to snorkel to see fish and corals. Professionally executed. - Very satisfied, the trip was incredibly nice and well done. The crew are service minded and have a lot of humour. The places we snorkeled were absolutely magical with lots of fish and coral. The lunch was very good and we had time to explore the beach on Koh Rok for a while before we traveled on.

Amazing experience & professional crew - We (2 adults, 2 kids, 7 & 10 years) had a fantastic day visiting Koh Ha and Koh Rok by speed boat. The crew was very professional and the “leader” spoke perfectly English. There were five crew onboard to help the guests and make sure everybody felt comfortable. There were enough space onboard and life vests for everybody also the kids. Our boy was a little scared jumping in the water but a very kind crew encourage him with kind words “You can do it, and it’s okay to be scared.” Overall a very positive experience - and we also saw a lot of beautiful fish when snorkeling.

Full day with snorkeling to Koh Rok and Koh Hah - What day ! We went to koh hah and smoked and snorkeled in several places. We got on board and were very well taken care of. High level of safety with life jackets and counting, but above all they kept an eye on everyone in the water (there were some who couldn't take it so they pulled them in with a buoy), we ate rice and chicken for lunch (pack crackers and fruit if that food doesn't fit) . On the way home, we drove past the monkeys in the swamp and fed them mangoes. To add, it takes 45 min / stop and then nice by speedboat (sit far forward in the boat and it sounds much less)

Fun day out snorkelling on beautiful islandS - Great trip - the whole family loved it. Snorkelling was excellent - Huge variety of corals, fish (lots of nemos) and even a sea snake. Lunch stop on Koh Rok was lovely and food delicious. Thanks to the boat crew for making the day so fun and relaxing. Highly professional team.

Excellent Trip! - It was a great trip with good service from start to finish! The guide was very friendly and gave us more knowledge about the places we were taking.

Fun trip to be recommend - Very good experience! Trip was well organized and they even solved our problem that we went with the wrong driver to the meeting point.

A great day with Opal Travel - Opal Travels provided a perfect snorkeling tour to Ko Rok and Ko Haa. They were timely, informative about all of the details and had suggestions about the places we snorkeled. Lunch was delicious. A great trip!

Amazing islands and snorkeling, but a bit large scale and impersonal tour - We travelled in a speedboat that could take 60 people (!) but we were fortunately only 25 guests, I don't know if they ever are full, but that would have been quite something else... Though it was quite windy when we left, the journey was comfortable (though noisy) and no one got sea sick that I could see. It's also quite convenient to that the speedboat is fast. The boat had a roof and roll down plastic windows that they removed in the afternoon. Our guide provided basic info in very basic English, such as how long we'd stay at at different stops, but there was no info about the islands or the reefs themselves, which was a bit of a shame. We felt a little bit left to our own devices, the staff didn't interact much with us. Masks, fins and life vests were provided if you wanted them. The food was good (chicken and veg in red curry sauce, chicken drumsticks, rice, fruit, soda) and they used proper plates and cutlery, no plastic, great! They were careful to always count the guests and had one guy in the water with a lifebuoy and also warned us when there were jellyfish nearby. A little girl got a lightly stung and they took good care of her. The snorkeling was amazing, clear water, lots of fish and beautiful coral structures. The beach on Koh Rok is absolutely stunning. We snorkeled from the beach too during the break on the island, and it was almost as good as from the boat. There was an option to skip snorkeling from the boat at Koh Rok and go directly to the beach, which could be a nice option for those with small kids. There were a lot of other tours of course, and the beach was a bit crowded, but it was still really nice. Koh Ha was also really cool with amazing small islands rising from the water. It's a much smaller place though and there's only a tiny beach to swim to.
