Tu Lan & Phong Nha Subterranean River Cave Expedition
Swim Underground Rivers, Trek Primary Jungle & Camp Inside Giant Karst Domes
The Cave Capital of the World — Subterranean Jungle Expeditions
Home to Son Doong, Hang En, and the Tu Lan cave system. Swim through underground rivers with headlamps, camp beside subterranean waterfalls inside primeval karst jungles, and explore wartime Ho Chi Minh Trail history.
45 minutes by private transfer from Dong Hoi Airport (VDH) or Dong Hoi Train Station (overnight sleeper train from Hanoi or Ninh Binh; 3.5 hours north of Hue).
Local Tip: Even if Son Doong is sold out a year ahead, the 2D1N–4D3N Tu Lan and Hang Va expeditions offer equally jaw-dropping subterranean camping.
Combine Phong Nha Caves with neighboring regions in our 60-Second Trip Planner or speak directly with a Hanoi route specialist.
