Phong Nha Cave by Son River boat
Phong Nha Cave is reached by boat from the tourism centre, with about 30 minutes on the Son River before the cave passage. The published route continues approximately 1200 m by boat inside, then visits dry sections on foot. Allow about 2.5 hours for the overall cave visit, rather than treating the river journey as the whole experience.
Tickets are bought at the counter and boats allocated at the pier. A stay in the village gives a base near the departure area, but the cave itself still requires the river journey. The accommodation guide explains village and countryside locations. For travellers arriving through Dong Hoi, organise the onward connection separately using the arrival guide.
Boat trips to Phong Nha Cave
Our take: The cave boat option offers several departure choices, while the Paradise combination adds a second cave. Choose the Tien Son combination to visit both named caves with admission included.

Admission per person and the price per boat
Phong Nha Cave admission is 150000 VND per person, with the return boat charged separately at 700000 VND per boat for up to twelve guests. Children under 1.3 m enter free. These are published tariffs read on November 14, 2026; retain the distinction between the individual cave ticket and the boat charge when arranging an independent visit.
A boat's capacity does not turn its tariff into an individual ticket price. For a guided outing, compare the included admission and boat travel with any separate costs instead of adding the independent tariffs to an already inclusive package. The wider Phong Nha tour comparison covers boat-and-walkway days and activity combinations.
Published summer and winter hours
Phong Nha Cave publishes daily hours of 07:15 to 16:30 in summer and 07:30 to 15:45 in winter. Use those as seasonal planning hours and ask which schedule applies to your date. Leave time for ticketing, boat allocation and the visit rather than planning arrival at the closing time.
Rain and rising water can restrict cave access. Check the day's visitor instructions before travelling to the boat centre and keep the plan flexible. Published opening hours should not be treated as a promise of a particular boat departure or of operation regardless of river conditions.
Tien Son as a separate cave combination
Tien Son requires its own 80000 VND admission ticket, even when paired with Phong Nha Cave. The combined return boat tariff is 750000 VND per boat for up to twelve guests. Children under 1.3 m enter Tien Son free. These published prices were read on November 14, 2026.
Tien Son adds almost 600 steps, so choosing both caves changes the physical demands as well as the tickets. Its general visitor section is about 400 m within a 980 m cave. The seven to eight hour Phong Nha and Tien Son guided day includes both admissions, dragon boat tickets, lunch, a guide and an air-conditioned vehicle. Its meeting point is an office in Dong Hoi; plan travel to that meeting point.
Guided departures and the cave's history
Phong Nha Cave guided boat outings offer different hotel departure options in Hue, Dong Hoi or central Phong Nha, with a listed duration range of 4 to 24 hours across options. Transport, guide, cave admission and the boat are included; La Vang Sanctuary and Vietnamese lunch belong only to the Hue option. Lunch is extra on the half-day Dong Hoi and Phong Nha versions.
The Paradise and Phong Nha day trip starts in Hue or Dong Hoi according to the option and includes both cave entries, Paradise buggy, boat, guide and lunch. Choose the single river cave visit when that is the focus; choose the Tien Son combination when a second cave and its stair climb appeal.
Phong Nha Cave also has a wartime history as a shelter and storage place, alongside the Son River ferries' transport role. That history belongs to the same landscape as the much older karst. For a contrasting dry cave route, see Paradise Cave rather than expecting another version of this boat journey.
