It is a mystery to me that not more people know about this place as it it's RIGHT in the middle of Krabi town. Not only is the mangrove walkway wonderful on its own, includes a lookout tower, and is free to visit, but at the end there will be boats waiting that you can choose to take to the other side. You'll want to do this, since on the other side there is a secret and impressively big cave with lots of history!

Please see my guide for "Khao Khanab Nam" for more info about the cave!
