Full description
Discover 4 of Ko Lanta's most beautiful islands on this activity. After getting picked up from your hotel by speedboat or truck, meet your crew and listen to a quick safety briefing before setting sail. Cruise in a comfortable speedboat towards Koh Mook where you will anchor in front of the spectacular Emerald Cave. Put your lifejacket on and swim through an 80-meter dark tunnel to finally reach a 360° rainforest wall which disappears into the clouds above, protecting a pristine lagoon, hidden within the island. Continue to Koh Kradan and snorkel in the crystal-clear waters of a shallow coral reef. At the beach, enjoy a delicious Thai buffet lunch then enjoy a stroll along the bay or relax on the beach's white sands before continuing to your next stop, Koh Chuak, a small island with its own unique charm. Here, snorkel beneath the aquamarine water and discover a new world of coral reefs, fish and other sea creatures. Finally, visit Koh Ngai. Discover complete serenity here as the island has no roads and shops at all. Its the perfect place to relax and bring the day to a close before heading back to your hotel on Koh Lanta.

Highly recommended tour. Very nice guides and you feel in good hands. If you like snorkeling it's the perfect trip, saw a lot of colorful fish and it was enough time, around 30-50 minutes per stop. The lunch was not bad but not a deluxe menu (there was rice with curry, vegetables, chicken and fruit).

We had a wonderful experience! The staff was welcoming and took great care of us all day. The highlight of the day was the visit to the hidden lagoon, the snorkeling (we spotted e.g clownfish, lionfish, harlequin sweetlips), and the crystal clear water and white sand beaches on the different islands. Lunch was tasty and the speedboat was modern and comfortable. We highly recommend this day tour!
