Top Ko Lanta Underground Tours

Great experience. The crew were super friendly, caring and supportive. They have really taken a great care of us with a wonderful attitude.rain no rain, the trip was really nice.

Great trip and very good value. Fish in the stops are beautiful even if the coral is pale, lunch was excellent and was great to Visit the other islands for future stay homework!

The transportation was on time. The service was hight guality. The staff was energetic and helpful. Lunch was good and there was enought food and drings. We are very satisfied and happy!

Super cool! took us to some really unique places and told us some history of each. had a very yummy lunch and snacks along the way!

Great guide ensuring no one was left behind. We even brought bake some people that were left behind from another company. Conditions got a bit rough at the end and there are alot of company's doing the same thing. But It is impressive on how everyone works together in tough conditions.

The four islands tour is very good. We recommend that you choose a tour with the Emerald Cave. It is stunning. Please note that you have to swim 100m through dark cave before reaching centre.

Excellent host & fantastic day. Only reason for 4/5 is the swim to the Emerald Cove. Guide dealing with a non swimmer and swam ahead with fins. It was pitch black without his torch and once he rounded a bend it was black and very difficult to avoid crashing into a wall - that was quite painful. Nice sized group of great individuals. Food lovely and guide was great

Swimming through the cave, paddling in the dark, only to emerge onto a beautiful beach hidden in the middle of the island was the highlight of the excursion and perhaps the entire Thailand trip.

A wonderful day! The beach we visited was beautiful, the team were super nice and made sure everyone was safe in the water, and the lunch and drinks were plentiful. The team sailing the boat were the highlight for me, they were great guys! I only gave it a 4 because my day started a little rocky, I was late to be picked up by almost an hour - more communication would’ve been helpful. But the tour itself was really fun!

Very nice experience. We choose the longtail boat knowing it will travel longer and we did enjoy all our time on it. We head to the 1st island to snorkel 30min, we head to the 2nd island and snorkeled 30min, we head to the cave (it is on the 3rd island) and stayed there other 30min (I had my diving torch so could see way more than the other tourists) and as final stop, we head to the 4th island to have a delicious lunch and the longest break (=1h). I am glad we took our find because they didn't provide that, but they did give mask and snorkel. I can recommend this tour and I hope my review helps in understanding the 4 island set up :)

My first time snorkeling was amazing. A bit crowded tour but I was lucky to be on the last boat (of many) going out which meant we had some alone time on each spot. Lots of fish, not so much colorful reeves. Our guide Ya was great, he seems to love his job and was very excited to help and take photos of everyone. Swimming through the cave into the hidden lagoon is a spectacular experience. They could go out with more space in between the boats so every group would have a little less crowded experience, but maybe that's tricky to arrange with tide etc. Anyways it's a cool trip, recommended.

The sea was a bit choppy when we went out but it was good fun! The first island is about an hour away and the snorkelling is good. The reef isn’t the loveliest but there are fish galore there. Spotting a giant clam was the highlight for me. The next snorkelling site was 15 mins away and was just as good. We then went to another island for lunch, which was a delicious curry on a really beautiful beach. We then went to the emerald cave, which is a unique experience; an 80m swim through a twisting cave until we reached a small beach surrounded by 100ft cliffs. After that it’s a 1 1/2 hour trip back to Old Town. We really enjoyed it ; the views were amazing, the cave was worth it all by itself, the guide was lovely and lunch was great. Highly recommend!

This is a great tour of beautiful islands. The snorkeling was really good and not rushed like some tours. The Emerald Cave is something you must experience while on Koh Lanta and definitely a highlight of the day. Our crew was friendly and accommodating. We recommend this tour.

One of the best trips we had in Thailand. It was very well organized. I was able to book the trip online instantly and was able to use my mobile ticket without any hassle of printing out tickets. We were picked up from our hotel on time, the trip was on an authentic long tail boat.Our guide is very helpful. He ensured I felt safe at times and even took me to the Emerald cave where you need to swim through a pitch dark cave to reach the Emerald pool. I am ever so thankful to guide for going the extra mile to ensure I experienced everything. Would recommend this tour to anyone in a heartbeat!

Great experience - snorkelling destinations were excellent and the staff were very nice. Lunch was also really good.

The islands were absolutely beautiful but there were way too many people, so they weren't the best snorkelling sites. You only snorkel at the first two islands, then go to the emerald cave (which is the highlight of the tour). The last island is just to have lunch, no snorkelling. But overall, the tour was good. I would recommend it for anyone staying in koh lanta.
