Tham Lod Puyu ( Puyu Passing Through Cave) is located at Khao Yakang, to the south of the Park. The ceilings of the cave are formed with exotic stalagmites and stalactites. Along both banks of Puyu canal mangroves grow in abundance. Tham Lod Puyu can be reached by boat from Tammalang Pier, which takes about one hour or two hours for a round trip.
