Detailed A–Z Guide to Visiting Phong Nha Cave

Before the boat takes you down the Son River and slowly enters the heart of Phong Nha Cave, there is one spot you definitely must stop by: Phong Nha Boat Station. This is the starting point for exploring this famous cave, located in Son Trach area, about 45–50 km northwest of Dong Hoi city center.

From Dong Hoi to Phong Nha boat station

• From Dong Hoi: You can travel by rented motorbike (around 150,000 - 200,000 VND/day), taxi (400,000 - 500,000 VND/one way for a 4-seater car), or bus route B4 (around 35,000 VND/ticket, running from Dong Hoi center). Travel time takes about 1-1.5 hours. If traveling by motorbike, follow National Highway 1A then turn onto Ho Chi Minh Highway West Branch (Road 20 Quyen Thang) to reach the pier.

• From other provinces: If flying to Dong Hoi Airport (from Hanoi or Ho Chi Minh City, flight time 1-1.5 hours), you can rent a motorbike right at the airport or take a taxi/shuttle bus to Phong Nha. From Hue or Da Nang, take a coach bus or drive yourself along the Ho Chi Minh Highway, taking 3-5 hours. From Hanoi, you can take a train to Dong Hoi Station and then continue as above.

Parking at Phong Nha boat station

If traveling by personal vehicle, you can park your vehicle at the pier area before starting the tour. Reference fees:

• Motorbike: 5,000 VND/vehicle

• Car: 17,000 VND/vehicle

After parking, you can proceed to purchase tickets and begin your journey to explore Phong Nha Cave. Families with young children should also check ticket policies based on height/age at the time of travel, as regulations may be adjusted.

Before stepping onto the boat and beginning your journey down the Son River, you will need to complete a simple task that should be prepared in advance: purchasing entry tickets to Phong Nha Cave. If traveling independently, you can buy tickets directly at the counter of the Phong Nha – Ke Bang Tourism Center, located right at the Son River boat station area.

• Ticket price (updated 2026): Adults: 150,000 VND/person/ticket. Children under 1.3m: Free. The ticket does not include cave boat transportation services. 

• Ticket counter opening hours: From 7:00 AM to 5:00 PM daily, which may be extended depending on the peak season (March - September).

If combined with a visit to the nearby Tien Son Cave, the separate ticket is 80,000 VND/person. It is recommended to buy tickets early on weekends or holidays to avoid long queues.

Visiting Phong Nha Cave must be done by boat because the entrance is an underground river. After completing the ticket purchase, visitors will be guided down to the pier to board a motorboat with a canopy, operated by local people. You can choose to share a boat with other guests or hire a private boat if traveling in a group.

• Shared boat: Suitable for individuals or small groups. Fixed boat price is 700,000 VND/boat, carrying a maximum of 12 people (including children). The cost is split equally among passengers, so if fully shared with 12 people, it is only about 50,000 - 60,000 VND/person. Boats are fully equipped with life jackets.

• Private boat: Ideal for families or groups wanting privacy. You pay the full boat fee (700,000 VND), even if there are only 4-5 people. You can request a private tour guide (additional fee of about 200,000 VND). 

Note: Boats are managed by the tourism center and cannot be rented outside. Shared boats are more popular during peak season to reduce costs.

The itinerary starts from the Son River boat station – a romantic river with emerald green water and majestic mountain landscapes. The total distance is about 5-6km, combining boat ride and walking.

• Phase 1: From Son River boat station to the cave entrance: The boat departs, heading down the Son River for about 30-45 minutes. You will admire the countryside scenery, limestone mountains, and crystal-clear river water (fish can be seen swimming during the dry season). The cave entrance is 20-25m wide, 10m high, with an inverted arch shape, making it easy for boats to enter.

• Phase 2: Entering the Wet Cave (underground river cave): The boat goes deep into the underground river about 1.5km long, with clear blue water. On both sides are stalactites sparkling under the lights, shaped like lions, unicorns, and palaces.

• Phase 3: Transferring to the Dry Cave: The boat docks, and you walk about 500-600m on a flat sandy ground to explore giant stalactites.

Throughout the journey, visitors always have a tour guide or boat driver introducing the history of discovery, geological values, and interesting stories associated with Phong Nha Cave, bringing an experience that is both safe and full of knowledge.

The average visiting time for Phong Nha Cave lasts about 2–3 hours, depending on the visitor's sightseeing pace and the day's weather conditions.

• Details: 30-45 minutes boat ride to the cave mouth and entering the wet cave; 45-60 minutes walking to explore the dry cave; 30-45 minutes returning. If combined with Tien Son Cave, add 1 hour.

• Total time: If coming from Dong Hoi, it takes half a day (morning or afternoon). Peak season may take longer due to waiting for boats.

Advice: You should start visiting around 8:00–9:00 AM to avoid crowds, enjoy the cool air, and limit harsh sunlight in the afternoon, helping your experience be more complete and comfortable.

As a famous attraction with a boat trip on an underground river and a natural cave environment, Phong Nha Cave requires first-time visitors to understand a few important notes before starting the trip.

• Safety: Always wear life jackets on the boat, do not swim or leave the group on your own. The cave has high humidity and slippery floors, so walk slowly. Children and the elderly should have assistance.
• Weather: Avoid the rainy season (September - November) due to dangerous flooding. Check the forecast 1 week in advance.
• Environmental protection: Do not litter, do not touch or damage stalactites. The cave is a UNESCO heritage site, and violations may be fined.
• Health: Bring personal medication if allergic to dust or cold. Do not participate if you have respiratory issues (humid air).
• Others: Feel free to take photos, but use flash to avoid dark pictures. If traveling alone, join a group at the pier for better safety.
