Thien Dong - Paradise Cave

Hidden amidst wooded karst peaks lies a breathtaking 31 km long underground network, though most visitors only explore the first kilometer. Its impressive scale unveils a cathedral-like space dotted with towering stalagmites and stalactites resembling otherworldly creatures, accessible by grand wooden staircases. For the best experience, an early visit is recommended to avoid the midday crowds, where tour guides shepherd groups with megaphones.
Paradise Cave is located about 14 km southwest of Son Trach. Electric buggies are available to transport visitors from the parking lot to the entrance 1 km away, with a one-way fare of 15,000 dong or a round-trip fare of 25,000 dong per person.
