Nguom Ngao Cave is a priceless gift from nature to the northern highland province of Cao Bang. It is situated on a mountain in Gun hamlet of Dam Thuy commune, Trung Khanh district. In the Tay ethnic language, Nguom Ngao translates to "Tiger Cave." This area allegedly once had a large number of tigers, who were then slain by locals to ensure their safety. As a result, the indigenous Tay people gave this place the name "Nguom Ngao".
