Sea kayaking and cave exploration is a niche travel activity that requires both natural setting and genuine sea tour expertise. Phuket is blessed when it comes to the former as you will find ample marine wonders scattered here and there, with special mention of the Phang Nga Bay. And for expert inputs, you can go back to John Gray's Sea Canoe. Founded by American naturalist and nature enthusiast John Gray in 1989, this organization will take you kayaking in some of Phuket’s most beautiful reefs, where you can be one with the azure waters. Spend a day traversing into old and far off caves exploring the mysteries that they have held hidden for decades!
