Phong Nha-Ke Bang: The Cave Kingdom
Phong Nha-Ke Bang National Park is a UNESCO World Heritage site containing the oldest karst mountains in Asia, dating back 400 million years. It is home to hundreds of cave systems, including the largest cave in the world, Son Doong.
Top Caves for Casual Visitors
Paradise Cave (Thien Duong)
Considered one of the most beautiful dry caves in the world. Visitors walk along a 1.1km wooden boardwalk inside a colossal cavern lit with soft lights. Entrance costs 250,000 VND.
Phong Nha Cave
Accessed by a 30-minute motorboat trip along the Son River. The boat turns off its engine and the rowers paddle you inside this massive wet cave filled with spectacular rock formations.
Dark Cave (Hang Toi)
An action-packed adventure featuring ziplining over the river, swimming into a pitch-black cave, and bathing in a thick, buoyant mud pool inside the cave chambers.
Multi-Day Trekking Expeditions
If you want to explore the deep wilderness, you must book with licensed operators. Oxalis Adventure holds the exclusive license for tours to Son Doong Cave (requiring bookings a year in advance and costing $3,000 USD) and Hang En (a 2-day trek that is highly recommended and more accessible).
The Bong Lai Valley Farmstays
For a unique accommodation experience, stay in the Bong Lai Valley just outside town. Stay in local farmstays, rent a bicycle, ride through pepper farms, and stop at "The Pub with Cold Beer" for fresh, farm-to-table food.
