In recent years, the Mooc stream, located near the western branch of the Ho Chi Minh Highway in Phong Nha-Ke Bang national park, has become a popular tourist destination, attracting hundreds of thousands of visitors.

The Mooc stream, along the Ho Chi Minh Highway in Phong Nha-Ke Bang national park, is renowned for its jade-green waters.

Located in the core zone of the Phong Nha-Ke Bang world heritage site, Mooc stream is enveloped by lush green forests.

Over the years, the Phong Nha-Ke Bang Tourism Center has developed various activities on the Mooc stream for visitors.

The Mooc stream has become a popular stop for international tourists exploring the legendary western branch of the Ho Chi Minh Highway. They enjoy adventurous activities and immersing themselves in the clear waters.

Along the stream banks, the tourism center has built eco-friendly wooden platforms to provide dining and resting areas for visitors.

Pham Hong Thai, director of Phong Nha-Ke Bang national park, stated that the source of the Mooc stream remains a mystery despite numerous expeditions involving international experts. Several years ago, cave explorers dived 70 m below the surface, into the limestone layers, but couldn't find the water source.

Blending with nature, the wooden path leading to the Mooc stream winds through the forest.

Currently, the Mooc stream and the Chay river are two popular spots for visitors seeking respite from the heat while exploring the Phong Nha-Ke Bang world heritage site.
