1. From Ko Lanta: 4 Islands Snorkeling Tour by Long Tail Boat
Start with pickup from your hotel in Koh Lanta Yai at 8:30 AM. Board the long tail boat in Koh Lanta's old town and travel first to Ko Chuek known as "Rope Island." Enjoy an opportunity to snorkel early in the morning while there are no currents and the water is amazingly clear and turquoise in color. Next sail to Koh Muk, or "Pearl Island", where the Emerald Cave is located. While in the cave, swim on the hidden beach and the lagoon, in what is the highlight of the day trip. Enjoy a delicious buffet lunch right on the beach at Koh Ngai, a lush paradise island teeming with colorful fish along its shores. After lunch visit Koh Maa, or "Horse Island." Here you can do more snorkeling, swimming, or relax for the remainder of the afternoon before being returned to Koh Lanta.
