Hang En

Top choice cave in Phong Nha-Ke Bang National Park

This gigantic cave is very close to Hang Son Doong, and both featured in a National Geographic photographic spread in 2011. Getting here involves a trek through dense jungle, valleys and the Ban Doong minority village, a very remote tribal settlement (with no electricity or roads). You stay overnight in the cave or in a minority village. Tours can be booked via Oxalis or local accommodation.
