Located close to the Kalimantan border, Silabur Cave is a limestone cave that is located inside of Mount Silabur and offers vertical cliffs. From the village, it is a one hour trek to the foot of the mountain.
From the foot of the mountain, you then need to trek up halfway which is roughly another hour before you reach the entrance of the cave at the mid of the mountain.
These caves have been long harvested for the prized bird's nest from the local swiftlets. A local association operates and manages the caves here, where bird next harvesting takes place a couple of times a year.
