Ke Bang National Park, a UNESCO world heritage site
in the central province of Quang Binh, will launch an adventure tour at
Toi Cave (Dark Grotto) this month, according to the Phong Nha-Ke Bang
Tourism Centre.
Some tourist guides working in the Phong Nha-Ke Bang tourism centre in
the central province of Quang Binh yesterday discovered, quite by
chance, an ancient jar inside the Phong Nha grotto.
