Exploring the Dry Cave and Bi Ky Chamber

After the boat ride through the flooded section, you disembark to explore the cave on foot. These elevated dry chambers hold ancient rock formations.

The standard tourist route covers 1.2 to 1.5 kilometers of the cave system. Once the boat stops inside, you step onto wooden and stone pathways to walk through the dry sections.

Formed over 400 million years ago, this area features giant stalactites and stalagmites. You need comfortable walking shoes with non-slip rubber soles, as humidity makes paths slick.
