Son Doong Cave

Quảng Bình, Vietnam

4.5 (0)

Overview

Largest cave passage in the world, located near the Laos-Vietnam border. It sits on the central coast, where the rains come in autumn rather than summer.

Why visit: Phong Nha holds the largest cave passage on earth, and several others big enough to hold their own jungle and weather.

Things to do

›Book the big caves months ahead — permits are strictly capped
›Wear shoes with grip; the floors are wet limestone
›Take a torch even on the lit routes
›Check seasonal closures, which are about flooding, not opening hours
