Itinerary

450 min

Enjoy a convenient pickup service either by local truck on road from the hotel lobby or directly by speed boat from the hotel beach on Koh Lanta. Meet the friendly and professional crew of Tin Adventure Sea Tour on the boat and get a warm welcome with safety instructions and important information about the tour program. Cruise by comfortable speed boat with 35 limited seats in less than 30 minutes to Koh Mook and anchor in front of the spectacular Emerald Cave - the highlight of the tour. Put your life-jackets on and swim through an 80-meter dark tunnel with headlamps between the group members. Finally, the daylight is started to stream through and you will discover a 360° rainforest wall which is disappearing into the clouds above, protecting a pristine lagoon, hidden within the island. Continue to Koh Kradan and swim in the open water with a shallow coral reef. A buffet lunch of local Thai food is served at the beach on the island. After lunch, you can walk along the beach for a bit, wade into the water, and just take it easy. This beach truly is serene – the water is crystal clear, and the sand is white and fine with seashells as you come closer to the water. The next snorkel stop is at Koh Chuak, a small island with its own charm that actually lies in the sea. Beneath the aquamarine water is a whole new world of colors created by coral reefs, fish and other sea creatures that needs to be explored. The last stop will be on Koh Ngai, also referred to as Koh Hai. It's another island off the coast of Trang without roads and shops at all, only with a couple of resorts, tranquility and a gorgeous beach scenery. This is the perfect place to relax and bring the day to a close before heading back to your hotel on Koh Lanta.

Overall, a good tour. The snorkeling was good, site beautiful. However, they say that the max number in the people boat is 35 but they crammed 40 in our boat and it was uncomfortably overcrowded. Everyone was practically in each other’s laps. As a result, we used a different tour operator for our Phi Phi island tour and found the boat far more comfortable.

4 Islands tour from Koh lanta

Very good experience with Nun (Leonardo di caprio) and his staff. Due to bad weather conditions, we need to change the orders of the islands and everything was done professionally. Regarding the 4 Islands, it was stunning ! But you will see by yourselves 😁😁😁

Fantastic experience. Super cute crew.

A fantastic trip. We were in doubt if it would be too hectic and for the time pressure with many tourists. But it was a super exciting trip. Snorkeling was great both at stop 2 and stop 3. At Ko Kradan, take your snorkeling equipment down past the toilets and then swim out to the corals at the small beach (this is the fence for the same purpose). There was a fantastic fishing life close to land and many on our trip did not really pay attention to that part. The cave was also exciting. A little challenge to swim in there. Wear life vests - even if you feel like you're a good swimmer. Then you don't panic in the dark. The crew was super cute and helpful and the lunch was good. A huge recommendation from here.

Very good company

Very nice tour and very well organized. The only thing I would say is the food is cold because it’s kept on the boat until it’s time for lunch. But everything else about the tour was very nice. The boat was also not over packed and it was easy to move around. Very helpful tour guides as well.

Tin Adventure 4 island trip.

The guides were excellent. The snorkelling was good and the beaches were great. The sea at the entrance to the Emerald cave was quite rough, a bit more direction to people to stay away from the sides of the cave would be advisable.

Crowded and touristy

Positives- hotel pick up and drop off was good and the food and water was good. Negatives- the boat wasn’t well set up for a day trip. Not much space to relax or to see any scenery when travelling. No boat briefing re our itinerary and the boat arrived at all places at the same time as lots of other boats so it was crowded. I’d always wanted to visit Ko Kradan but the reality was that you get dropped off in the edge of the island with everyone else and stand up to eat lunch on the edge of a narrow slip of sand. Emerald cave. No briefing about what to expect. The cave is beautiful but is packed with tours going through and so you get kicked and jostled a lot. It’s tidal and so hard to swim even for strong swimmers with life jackets. Some boats had a system where they escorted people through in a chain. Our boat left everyone to sort themselves and it was very dangerous, dark as the tour leader wasn’t close by with head torch. Recommendations- limit tour numbers allowed to go into and out of the cave at any time. One in and one out. Tour operator needs a better boat briefing and must do the safety system for getting people in and out. All in all- too many people and not a relaxing day. I wouldn’t recommend it.
