About this tour
Spend nine hours exploring two of Vietnam's most dramatic cave systems in Phong Nha-Ke Bang National Park. You'll zipline 400 metres across the Chay River into Dark Cave, soak in natural mud pools, navigate underground chambers with a knowledgeable guide, then cruise by traditional dragon boat through Phong Nha Cave past colossal stalactites and an subterranean river. Lunch and hotel transfers from Dong Hoi or Phong Nha village are included, along with travel insurance and drinking water.

What to expect
You'll start with hotel collection, then head to Dark Cave where a guide briefs you on safety before the zipline harness goes on. The 400m crossing takes minutes; the rush is real but controlled. Post-landing, you'll wade into cool mud pools—genuinely therapeutic—then explore the cave's lit passages on foot. The second half shifts mood entirely: a serene dragon boat glides through Phong Nha Cave's entrance chamber, where limestone walls tower overhead and water reflects the formations above. The underground river here stretches longer than any other in Vietnam. Lunch breaks the day midway. Expect to be damp throughout; bring a change of clothes.
Good to know
Not suitable if you have spinal issues, are pregnant, have poor heart health, or use mobility aids. The zipline and mud bath are only available on the full package option. Tet holidays incur a 5 USD surcharge per person. Pick-up outside Dong Hoi or Phong Nha village attracts extra fees. Wear water shoes or sandals that stay on when wet.
