Absolutely incredible. had one of the best experiences ever! went with my 7 year old son whos on the spectrum and he loved every minuet. was simple and easy cant wait to book my next adventure! Thankyou x
I don't think it's much different from ordering through a tour company in town, but I didn't want to spend as much cash as possible, so I decided to order through Klook. The tour went around several islands and snorkeling spots, and the beach on Koh Ngai was especially beautiful 🏝️ The long boat ride there and back was quite shaky, so if you get motion sickness easily, be careful. I still got motion sickness even after taking motion sickness medicine 😂 It was great because they gave me a lot of fruit ~ 🍉🍍
Amazing tour by Amazing skilled driver and also his 2 assistants. Enjoyed the whole experience and services. Recommended!!!! Love the food cooked by one of the (a 17yo boy) staff's mum. Will go back again for sure!
Emerald cave is spectacular. The captain and his team are professional and taking good care of everyone. Highly recommend it!
Everything was top class, the guide with his professionalism and smile, the mix of activities and the food provided. I recommend this tour to everyone!
It's a worthwhile experience at a reasonable price. Good service, hotel shuttle, long-tail boat is ok. Coral is not so beautiful because of global warming. Emerald cave is exciting but tiring to swim. See only foreign tourists.
Overall very satisfied with the tour. If you’re expecting a tour to stick perfectly to the itinerary, you are in the wrong country. But we had enough time at each spot to really enjoy it, and the beach where we eat lunch and relaxed was absolutely perfect. We even saw a beautiful hornbill. The 80m swim through the cave was less scary than expected, but I’d recommend making sure you stay close enough to the guide to see the light from their headlamp. It gets very busy in there and there are several groups coming and going at once. Still, if you adjust your expectations, it’s great value for money and the places you’ll see are stunning! Note: If you are vegan/vegetarian I highly recommend eating a big breakfast and bringing a snack, as the veg option was white rice and cabbage.
highly recommend!! was a really lovely day. Our guide was lovely and everything was explained well. It finished earlier then expected but still feel like we got our moneys worth! (back to hostel at 4) Also the lunch was amazing!! massamam curry on the beach
good tour and good value for money. The crew were really nice and lovely and the tour was fun! however we spent most of the day on the boat (which you were packed into it like sardines) and not much time snorkelling. Also if you haven’t snorkelled before, make sure to watch a video as they don’t show you! inside the cave was nice but they took us there high tide so was a little dangerous. If you’re not a confident swimmer I don’t recommend the cave, or at least in my experience. the rest was great though and definitely a fun experience to do, especially for the price
Beautiful landscapes, I recommend this excursion. 2 snorkeling spots, swimming in a cave, lunch and free time on a beach. Group of 15/16 people.
Good to know
On this one-day trip you will discover 4 iconic islands in the south-east of Koh Lanta. Get picked up from your hotel and head to the pier in Lanta Old Town. Board the 'My Lanta' traditional longtail boat with an English speaking guide and depart to the 4 Islands.
You will arrive at the first snorkel spot after a ride of approximately 45 minutes. Swim in the crystal clear water of Koh Chueak, a small karst islet with sea caves and small sandy beaches between Koh Mook and Koh Ngai.
Around an hour later visit Koh Mook, the largest island on this tour. It is best known for its Tham Morakot (which means Emerald Cave in Thai) and blue lagoon with a secret beach in the center of the island. The entrance to the cave is located on the western side of the island and is only accessible during low tide. The cave itself winds for about 80 meters to its other exit, onto a white beach with an emerald pool surrounded by steep cliffs.
Continue to Koh Ngai to enjoy a delicious Thai picnic lunch on the beach, consisting of steam rice, fried mix vegetables, Massaman Curry with chicken and seasonal fruits. Koh Ngai is a charming island that features a dramatic interior and a spotless sandy beach along its eastern coast. Mountainous and covered by tropical forest, the island is surrounded by clear waters with magnificent corals, making it a perfect site for snorkeling.
Cruise further to the 2nd snorkel stop at Koh Maa where you can feed the fish with bread or bananas. Thousands of giant bats can also be seen here. Head back from Koh Maa to Koh Lanta and arrive at the port in the old town at approx. 15.30. Get transferred back to your hotel on Koh Lanta.
This trip is for everyone who loves water activities and is not afraid to swim through a cave in perfect darkness for about 80 metres!
