5* Recommend! - Amazing day visiting the 4 islands by big boats. Mon was a brilliant host! All the food that was put on was absolutely delicious. Snorkels, goggles, flippers we’re all provided and looked brand new. Efficient pick up and drop off from where we were staying. Super friendly staff. Would definitely recommend using thefourislands.com

Wonderful - We took the speed boat tour to four islands. The Emerald cave was amazing and we were lucky to be there on a day when it was not so crowded. Other people, who went on a tour closer to Christmas holidays, said it was so crowded the cave was blocked like during a traffic jam, which was not fun. Bring a flash light suitable for water, as only the guide has one and it's not enough in the cave. Snorkeling at the beach where we had lunch was fantastic, another snorkeling location was not as good as the visibility was not great but I saw a sea snake for the first time, so that was fun! Overall, do not miss this tour if you can, it's worth it.

Offseason nice - highseason might be hell - I was in the offseason there - so there were only 50 people - beware of going there in high season - there might be 100 swimmers trying to get in and 199 want to get out.... the crossing to the hidden place thru the tunnel is not too easy and dark. If you are inside - its an enjoyable little spot.

Overall nice adventure - A nice and slightly rough-around-the-edges island-hopping adventure. We selected the trip with one snorkeling stop. They put us on the trip with three stops instead without telling us. During the trip we had lunch on an awesome beach and visited an incredible beach only accessible by swimming. The workers were friendly and considerate. I recommend it, as long as you’re open to an imperfect experience. Some things to be aware of: they crammed our boat full of people, the journey to the islands is long (75 minutes one way?), they only handed out one bottle of water and one soda per person so bring water, some people had to sit in the direct sun the entire way.

A nice experience - The trip involves a hotel pick up, travel to pierside, a long boat trip and Island hopping. The kayaking part and going into the cave is great fun... The boat trip can get a bit boring but the crew is friendly and you can suck on watermelons provided by the crew to cool you off. Overall a pleasant trip

Slow boat. 75% of trip is traveling - Nice big boat and friendly crew. Some ok spots too see. Specially the Emarold cave was nice. But most of the time is on the boat and waiting to get to the next location. Was almost 2 hours delayed when we took the trip. 2,5 hours on locations on a 10 hour trip is to little.

Not what we expected - I would not recommend this tour unless you are fine with most of the day being spent on the boat. Going into the event, we were expecting a day full of snorkeling and activities. The itinerary of the event is as follows: - 1st stop Koh Chuak: Here we all got off the boat to snorkel or kayak (if you bough the with kayak package). Not much to see here in terms of fish or reefs. In my opinion this stop could have been skipped. - 2nd stop Koh Ngai: We got off the boat here while they prepared the lunch on board. Very pretty beach and island to take pictures and swim. Lunch was served on the boat, nothing special and served lukewarm. Rice, Fried chicken, sautéed vegetables and a thai chicken curry. - 3rd stop Koh Kardan: At this stop we anchored about 100 meters off shore. This was the final and best stop for snorkeling. Saw quite a lot of bright fish and a large coral reef. - 4th stop Koh Mook: This was by far the most spectacular stop of the day. They took us through the Koh Mook emerald cave. This was the must see on this tour. All stops lasted only 40 minutes each. In the 8 hour day, we had 2h40 of activities and 5h20 of sitting on a boat. All staff was very friendly, kind and professional.
