Why the Dark Cave Zipline is a Must-Do Adventure

Dark Cave, locally called Hang Tối is in the heart of Phong Nha national park, where its unlit basalt-and-limestone chambers remain largely untouched by artificial lighting. Far from a tranquil walking cave, it’s an action-packed playground: you’ll zip over the Chay River, swim to the cave mouth, trek through an underground chamber, float in a mineral-rich mud bath, then paddle back in a kayak.

The Zipline: Soaring Over the Chay River

You’ll launch from a platform and zip approximately 50 meters straight over the jade-green Chay River at speeds of up to 45 km/h - Vietnam’s longest double-wire zipline - before splashing into the water to swim the final stretch to the cave entrance.
