The draw here is the water itself. Locals call it the Two-Colour Canal, because freshwater flowing out of the ground meets saltwater pushing in from the coast, and on a good day you can see where one gives way to the other. Add mangrove forest and limestone karsts standing over the channels, and you get something quite different from the beach circuit most people do in Krabi.

You see it by kayak, mostly. The channels are sheltered and the current is gentle, so it works for families and for anyone who hasn't paddled before. Go slowly and look up now and then, because the light coming through the mangrove canopy is half the reason to be there, and birdwatchers do well on the quiet stretches. My advice is November to April, when the weather behaves and the water runs clearest. Wear something that dries fast, bring sun protection, and pack a light rain jacket anyway.
