Surrounded by forested karst peaks, this remarkable cave system extends for 31km, though most people only visit the first kilometre. The scale is breathtaking, as wooden staircases descend into a cathedral-like space with colossal stalagmites and glimmering stalactites. Get here early to beat the crowds, as during peak times (early afternoon), tour guides shepherd groups using megaphones. Paradise Cave is about 14km southwest of Son Trach. Electric buggies (per person one-way/return 15,000/25,000d) ferry visitors from the carpark to the entrance.
To explore deep inside Paradise Cave, consider booking Phong Nha Farmstay's 7km Paradise Cave tour (2,650,000d, minimum two people) which includes a swim through an underground river and lunch under a light shaft
