Where is Ruc Mon Cave? This cave is located in Trung Hoa and Hoa Son communes, Minh Hoa district, Quang Binh province – about 100 km northwest of Dong Hoi city center. Situated in the buffer zone of Phong Nha – Ke Bang National Park – a World Natural Heritage site recognized by UNESCO in 2003, Ruc Mon Cave is part of a massive cave system comprising over 300 large and small caves. Spanning an area of 85,754 hectares along the Viet-Lao border, this National Park is a famous "Kingdom of Caves" featuring Son Doong, Phong Nha, and Paradise Cave.

Regarding outstanding features, Ruc Mon Cave is 2,863 m long, with a ceiling over 50 m high (up to 300 m at some points), and boasts the longest underground river in the Phong Nha system at 1.5 km in length. Inside the cave lies a diverse world of speleothems: stalagmites and stalactites formed in countless shapes, from giant stone pillars to crystal-clear lakes. Its rich ecosystem hosts hundreds of rare flora and fauna species, including endemic species such as peacocks, langurs, and cave insects. Not only an adventure destination, the cave is also an ideal spot for trekking through primary forests and the village of the Ruc ethnic minority, offering a perfect blend of nature and local culture.
