4 Island Snorkel Tour to Emerald Cave by Speed Boat from Koh Lanta
Island Hopping to Koh Chuak, Koh Kradan, Koh Mook and Koh Maa
Embark on a cruise by speed boat to the southern islands of Lanta. Enjoy a full-day excursion with plenty of water activities and beach life on Koh Chuak, Kradan, and Mah. The highlight of this trip are the Emerald Cave on Koh Mook, a lesser-known lagoon with a 85m tunnel.
- Open water snorkeling at Koh Chuak
- Float into the Emerald Cave on Koh Mook
- Relax and sunbath at the beach of Koh Kradan
- Splash and snorkel at Koh Maa
Your next destination will be Koh Mook, which is renowned for its Emerald Cave. The entrance to the Morakot Cave is located on the western side of Koh Mook, and can be accessed only by swimming through a 85 meter tunnel to the other exit, opening into a white beach with an emerald pool surrounded by steep cliffs.
A delicious lunch will be served on Koh Kradan, a stunning island with a spotless sandy beach surrounded by clear waters with magnificent corals, making it a perfect site for snorkeling.
After lunch, continue to the small karst islets named Koh Cheuk, Koh Mah, and Koh Waen. They offer great snorkeling spots, sea caves, and small sandy beaches. Here you will be able to feed the fish with bread or bananas. Thousands of giant bats can also be seen there.
If the sea conditions are too rough to go to the small islets, you will instead stop at Koh Ngai. It is a charming island covered by tropical forest and a sandy beach along its eastern coast.
Return back to Koh Lanta around 4pm for transfer back to your hotel.
