Stonehenge
Thailand
Stonehenge is a superlative dive site and must be considered one of the top scuba spots in Thailand. Stonehenge is located only 5-10 minutes from Koh Lipe by boat and is full of Soft Leafy Coral making it a beautiful and vibrant reef. Generally you will see schools of Barracudas, Trevally & Yellow Snappers. Smaller creatures include Seahorses, Shrimps, Crabs, Nudibranchs, Seamoths, Stonefish & Frogfish. As this site is very exposed, strong currents can be expected, meaning diving here around Full or Black moon is not usually possible.
Koh Haa
Thailand
Once in Lanta, going scuba diving in Koh Haa is a must! The islands are six beautiful uninhabited limestone islands 16km west of Koh Lanta, inside the Koh Mu National Park. Whale Sharks might be spotted all year round even though Koh Haa diving site is more famous for Tigertail Seahorse, Hawksbill Turtle, Bluspotted ray, Spotted Garden Eels, Pipefish, Gosthpipefish, Barracuda and Banded Sea Snake.
