It’s incredible to think that such a beautiful landmark could have played such an important role in history.

Friends gather to celebrate with local rice wine and karaoke sessions. Visitors are welcomed with open arms and often take part in local celebrations and family dinners.

Son Doong Cave


Son Doong Cave – The world’s largest cave

The world’s largest cave, Son Doong, measures 9 kilometers in length and has a capacity of 38.5 million cubic meters. The cave’s magnificent dimensions never cease to astound, with its largest width stretching to 150 meters and its highest cave arch reaching an astounding 200 meters in height. To put this into perspective, picture cramming 15,000 Olympic-sized swimming pools and a 40-story skyscraper within!

Explorers might be amazed at the breathtaking underground ecosystem with abundant greenery, unusual plants and animals inside Son Doong Cave. It is an experience that reminds you of the strength of life and the mighty powers of nature, yet it is also humble and uplifting.

Tu Lan Cave System

A chain of streams slicing through the countryside connects the Tu Lan cave system. Millions of years passed throughout this process, creating a collection of caverns that are remarkably distinct from one another. 

Song Cave, one of the oldest caves in the Tu Lan system, is known as the most peculiar structure. There are coral reefs, patches of cauliflower, and subterranean “fields” filled with tiny stalagmites that resemble seaweed preserved in time. Another artist is Ken Cave. Here, stalactites that have been shaped by the wind to resemble flowing curtains or the claws of legendary animals may be found. Others protrude from the ceiling like long plastic straws, hidden from the weather.

En Cave


En Cave Entrance

A Phong Nha-Ke Bang National Park trek leads you to En Cave, the world’s third-largest cave. It has a large passage running through a limestone mountain, with three entrances that are up to 110 meters high, a ceiling that reaches 145 meters at its highest point, and the widest section of the passageway reaching up to 200 meters. Inside En Cave, there is a clear stream that flows through the cave, eventually heading to Hang Son Doong.

Its unique avian population and enormous size make En Cave a significant site for conservation efforts.

Va Cave

One of the significant caves in Phong Nha-Ke Bang National Park is Va Cave. Situated around 50 meters from the entrance to Son Doong Cave, it is situated deep within the national park. Scientists think these caves are related hydrologically. Its noteworthy feature is the tower cones, which are a type of cave formation with an intricate structure and a huge population.

Paradise Cave

Paradise Cave is a 31-km-long wonder that you enter via a wooden staircase leading to a grand chamber. The cave is renowned for its high ceilings adorned with beautiful stalactites, some reaching down into the cavern below. While most tourists explore just the first kilometer, kayaking options allow for deeper exploration. Like all caves in the region, Paradise Cave is governed by strict conservation guidelines to protect its unique features.

Phong Nha Cave


Boarding a boat into Phong Nha Cave

For a more tranquil experience, take a serene boat ride on the Son River to Phong Nha Cave. As you journey through, you’ll be surrounded by lush greenery and magnificent karst mountains. The cave is stunning, featuring stalactites and stalagmites resembling a giant monster’s teeth. With only 400 meters open to tourists, the cave offers a more relaxed exploration, yet its unique formations and status as the region’s namesake make it a high-priority conservation site.

Other Things To Know Before Traveling To Phong Nha

Best Time To Visit Phong Nha Caves

  • For the optimal experience, aim to visit during the dry season from April to August. This period offers the best conditions for exploring the underground rivers and wet caves. It’s also the ideal time for indulging in adrenaline-pumping activities like kayaking, zip-lining, and hiking.
  • You should avoid the rainy season from September to November. Many tourist sites are closed during this time due to extreme weather conditions like floods.
  • Check the weather forecast before your trip, then book accommodations and activities in advance, especially if you plan to visit during these popular months.

How To Get To Phong Nha Caves

  • Option 1: Via Dong Hoi City

The first way to reach Phong Nha-Ke Bang National Park is to travel to Dong Hoi City, which is accessible by both plane and train. Once you arrive in Dong Hoi, you’re about 45 kilometers away from your final destination.

Simply drive northwest along National Road 16 until you reach the Son River. A boat ride along this river will take you straight to Phong Nha Cave. The journey from Dong Hoi’s city center to the cave usually takes around 1.5 hours. This route offers the flexibility of adding a stopover in a bustling city, where you can explore local markets, dine on local cuisine, or even take a quick beach trip.

  • Option 2: The Sleeper Bus Experience

If you’re looking for a different kind of travel experience and have some time to spare, consider taking an overnight sleeper bus. These buses are particularly popular for routes from Hanoi, which take about 9 hours. Buses are also available from nearby cities like Da Nang and Hue. Sleeper buses offer a more budget-friendly option and a chance to interact with other travelers, making your journey to Phong Nha an adventure in itself.

What To Wear

  • A good, well-worn pair of boots, sneakers, or trail shoes is advised.
  • Wearing moisture-wicking clothes is better than dressing in layers for temperature regulation.
  • Dress athletically for the summer vacation, and merely pack a jacket if it gets chilly.
  • Bring swimsuits if the activities include and extra clothing in case you need to change.
