A boat trip through the eerily scenic mangrove-lined channels of the Krabi estuary is a fun way to gain a different perspective on the area. As well as a close-up view of the weird creatures that inhabit the swamps, you’ll get to visit a riverside cave or two. Tours are best organized directly with the longtail boatmen who hang around Krabi’s two piers and the surrounding streets, but can also be arranged through most tour agents.
The estuary’s most famous features are the twin limestone outcrops known as Khao Kanab Nam, which rise a hundred metres above the water from opposite sides of the Krabi River near the Maritime Park and Spa Resort and are so distinctive that they’ve become the symbol of Krabi. One of the twin karsts hides caves, which can be explored – many skeletons have been found here over the centuries, thought to be those of immigrants who got stranded by a flood before reaching the mainland. You can also choose to visit the Muslim island of Ko Klang.
