Phong Nha-Ke Bang National Park, near Dong Hoi, is home to some of the world's biggest caves. Three are easy for most visitors: Phong Nha Cave (a boat ride into a river cave), Paradise Cave (Thien Duong, a huge, lit, walkable dry cave) and Dark Cave (kayak, swim and mud bath). The legendary Son Doong is a multi-day expedition with a single operator and a very long waiting list, far beyond a day tour.

The caves to choose from
Phong Nha-Ke Bang National Park, near Dong Hoi, is home to some of the world’s biggest caves. Three are easy for most visitors: Phong Nha Cave (a boat ride into a river cave), Paradise Cave (Thien Duong, a huge, lit, walkable dry cave) and Dark Cave (kayak, swim and mud bath). The legendary Son Doong is a multi-day expedition with a single operator and a very long waiting list, far beyond a day tour.
Classic combos
The most popular day trip pairs Paradise Cave in the morning with Phong Nha Cave by boat, or Paradise with the adventurous Dark Cave. Paradise is the most spectacular for scenery and the easiest for families; Dark Cave suits active travellers wanting ziplining, swimming and mud. A two-day visit lets you add the Botanic Garden and a zipline or a longer trek.
Practical tips
Most tours leave from Phong Nha village, where most travellers stay, with hostel pickups. Paradise Cave day tours run roughly $30-50; Dark Cave combos similar; a professionally guided trek or a Son Doong expedition costs far more. Wear shoes you can get wet, and note that caves can close after heavy rain in the wet season.

Frequently asked questions
Which Phong Nha cave should I visit?
Paradise Cave for the most spectacular, walkable scenery; Dark Cave for kayaking, swimming and a mud bath; Phong Nha Cave for a classic river-boat ride into a cave. A day trip often combines Paradise with either Phong Nha or Dark Cave.
Is Paradise Cave or Dark Cave better?
They are different: Paradise Cave is a long, lit, dry cave for sightseeing that suits everyone; Dark Cave is an active adventure with kayaking, ziplining and mud. Choose Paradise for scenery, Dark Cave for adrenaline, or do both in one day.
How much do Phong Nha cave tours cost?
Day tours to Paradise or Dark Cave run about $30-50 per person including transport and entrance; boat trips into Phong Nha Cave similar. Multi-day treks and the Son Doong expedition cost far more and must be booked well in advance.
Can I visit Son Doong cave?
Son Doong is only accessible on a multi-day expedition with a single licensed operator, at a high cost and with a long waiting list — book many months ahead. Most travellers instead enjoy Paradise, Dark and Phong Nha caves.
When is the best time for Phong Nha cave tours?
February to August, the dry season, when caves and trails are open and rivers are calm. September to November brings heavy rain that can close caves and cancel treks; check conditions and allow a buffer day.
