Thien Duong (Paradise) cave - Phong Nha Ke Bang national park

Thien Duong (Paradise) cave is about 500 stairs up to the entrance of the cave, another 100-200 stairs down inside. Stunning, tastefully lit cave features along 1.1 km of new (spring 2011) wooden pathways. Some claim that this is among the most beautiful caves in the world.

Only open to the public since 2011, this remarkable cave system extends for 31km, though only a kilometre or so is accessible. Thien Duong (Paradise) cave is said to be the longest dry cave in the world.

Once you’re inside, the sheer scale of Thien Duong (Paradise) cave is truly breathtaking, as wooden staircases descend into a cathedral-like space replete with colossal stalagmites and glimmering stalactites of white crystal that resemble glass pillars.
