Experts from Phong Nha-Ke Bang Eco-tourism and Culture Centre have just discovered two lakes in Phong Nha Cave.

The centre Director Le Thanh Loi said the lakes were around 500 metres from each other. The first stretches 70 square metres while the other is over 300 square metres. Experts have yet to determine how deep Xuyen Son Ho Lake is.
This is the second discovery this year at Phong Nha Cave after a colour-changing stalactite was detected in July.
From October 1 this year, the centre will open the Xuyen Son Dong cave for tourists and will hold a contest to name the 300-square metre cave.
