The Vietravel agency is co-operating with Vietnam Airlines to offer a stalactite tour to the northeastern region of the country, with highlights in Nguom Ngao – a spectacular cave with stalactites of various shapes in the northern province of Cao Bang.

Nguom Ngao Cave in Trung Khanh District's Dam Thuy Commune, some 90km from provincial centre and just 3km from Ban Gioc Waterfall, is in a limestone mountain range, with some parts underground and some parts under water.

The Royal Exploration Team from Britain inspected the cave in 1995 and found the grotto to be 2,144m long.

The tour by Vietravel also includes other famous destinations such as Dong Van Plateau, Meo Vac District and Lung Cu Flagpole in Ha Giang Province, and Ban Gioc Waterfalls and Pac Bo Tourist Park in Cao Bang Province.-VNS
