Where is Phong Nha Ke Bang National Park?

From central Vietnam’s Quang Binh province is Phong Nha-Ke Bang National Park, a land of awe-inspiring beauty celebrated for its subterranean world of immense caves and stunning biodiversity. This remarkable destination is located about a four-hour drive (200 km / 125 miles) from Hue, the nation's former imperial capital.

Inaugurated in 1986, the park was honored by UNESCO in 2003 as a World Heritage site for its extraordinary geological history. It protects Asia’s oldest karst mountains, an ancient limestone landscape that tells a 400-million-year-old story dating back to the Paleozoic Era. This dramatic setting also serves as a vital sanctuary for a rich and diverse ecosystem.

You will have the chance to disembark and walk through a large, dry cavern to admire the magnificent geological formations up close.

Once-in-a-Lifetime Expeditions into the Phong Nha area

Hang Son Doong

The undisputed centerpiece of Phong Nha-Ke Bang National Park is Hang Son Doong, which holds the official Guinness World Records title for the largest natural cave on Earth.

Its scale is almost unimaginable. The main passage stretches for more than 5 kilometers (3 miles), reaching heights of 200 meters (650 ft) and widths of 150 meters (500 ft). This immense cavern is so vast it could house an entire New York City block, complete with 40-story skyscrapers. It also contains its own lush jungle ecosystem and a subterranean river, creating a unique world of its own.

Access to this pristine natural wonder is strictly limited to a few hundred visitors each year on professionally guided, multi-day expeditions, making it one of the most exclusive adventure travel experiences on the planet.

Hang En

As the world's third-largest cave, Hang En provides an adventure that is both spectacular and more accessible than its famous neighbor, Son Doong.

The 2-day, 1-night expedition leads you through pristine jungle and across numerous rivers. It’s a challenging journey that builds anticipation for the destination. The cave's entrance is jaw-dropping, but the true reward lies inside: a massive chamber where you will make camp on a sandy beach beside a serene, emerald-green lake.

This experience often inspires a moment of pure awe. While the trek covers roughly 25 km (over 15 miles) of hilly terrain and requires a moderate level of fitness, it pays off with a profound sense of discovery inside one of the planet's great natural wonders.

The Tu Lan Cave System

The Tu Lan cave system is known for its "wet cave" tours, where you will spend a lot of time swimming through underground rivers.

You can choose from single-day trips to multi-day expeditions. Each tour is a mix of trekking through valleys and swimming inside the caves, with some swims covering up to 500 meters (1,640 feet) in the dark. On longer trips, you also get to camp outdoors near waterfalls.

Because this is a water-focused adventure, knowing how to swim is a requirement. You should be prepared and comfortable with being wet for most of the journey.

Phong Nha Beyond the Caves

Ride the Phong Nha Motorbike Loop & Explore by Bicycle

One of the best ways to experience the Vietnamese countryside is to explore the area around Phong Nha by bicycle or motorbike.

The local roads will take you through vast rice paddies and small farming villages, where you'll often see water buffalo grazing by the roadside. The entire landscape is defined by the impressive limestone karst mountains that rise out of the fields.

For some of the most dramatic scenery, consider riding the well-known loop along the Ho Chi Minh Highway West. This route offers incredible mountain views from several free lookout points, giving you a great opportunity to slow down and see the authentic, day-to-day life of rural Vietnam.

Discover the Bong Lai Valley

The Bong Lai Valley is a peaceful stretch of countryside near Phong Nha, known as the perfect spot to unwind for an afternoon.

A popular activity here is to rent a bicycle and explore the quiet roads that wind past farms and fields of corn and peanuts. The valley is famous for a few quirky local businesses that have become must-visit stops. Highlights include The Pub with Cold Beer, renowned for its farm-to-table grilled chicken, and The Duck Stop, where you can feed a flock of ducks for a uniquely fun and chaotic experience.

Explore the Eco-Parks

For families or visitors looking for an organized outdoor activity, the Botanical Garden and Ozo Park are excellent choices.

• Botanical Garden: For a small fee (40,000 VND, or less than $2), you can take a relaxing walk on jungle trails to Gio Waterfall and Vang Anh Lake. It's a great, peaceful way to see the area's native plants and wildlife.

• Ozo Park: This park is for more active fun, offering treetop obstacle courses, ziplines, and kayaking. You can choose a ticket package that best fits your family's ages and interests.

Discover Wildlife and History

A unique experience in Phong Nha is joining a wildlife conservation tour. On these tours, you can help with conservation work by preparing food for animals, such as macaques and langurs, that have been rescued from illegal poaching. It's a hands-on way to learn about the challenges of wildlife protection and see the park's efforts up close.

For a look into the area's more recent history, you can visit the Eight Lady Cave (Hang Tam Co). It is a moving memorial to eight young volunteers who died tragically during the Vietnam War when a bomb blast sealed the cave they were using for shelter.

Kayaking on the Son River

Kayaking on the Son River is another popular activity in Phong Nha. It offers a different perspective, allowing you to see the impressive limestone karst mountains up close as you paddle along the water.

While the river is generally calm, this activity does require a moderate level of fitness.
