Hang Va Expedition Tour

The 2-day, 1-night Hang Va Expedition reveals the wonders of Nuoc Nut Cave and Hang Va Cave, known as the world's two most unique wet caves. Hang Va was featured in Planet Earth III - BBC's famous documentary series, showcasing its exceptionally rare towering cones emerging from emerald-green waters. This tour is ideal for adventurous travelers seeking mountain trekking, rope traversing, and overnight stays in a jungle campsite. The experience is particularly rewarding for photographers.

The 2-day Hang Va Expedition Tour will offer a unique experience with 1 night of camping in the forest. The Hang Va Expedition will take you to explore 2 caves: Hang Nuoc Nut and Hang Va.

Located in the core zone of Phong Nha – Ke Bang National Park, close to the exit of Son Doong Cave, Hang Va (Va Cave) was discovered by Mr Ho Khanh in 1992 and surveyed by the British - Vietnam Cave Expedition team led by Howard Limbert in 2012.

Hang Va is considered a special cave in the world of cave formations, with a river passage below and a large high-level passage above with dozens of tower cone formations. There are cones of different sizes and shapes, with the tallest tower cones being around 2 meters high. Geologists yet cannot confirm how these cones have formed. They are located in giant gour pools behind huge gour dams.

Hang Va and Nuoc Nut Caves were introduced in the "Otherworldly landscapes: 7 of Vietnam’s best cave experiences" by CNN Travel. Hang Va was also featured as the coolest new adventure in Asia by Forbes.

On November 26, 2023, Hang Son Doong, Hang En and Hang Va were featured on Episode 6 - EXTREMES of the famous documentary series Planet Earth III made by BBC.

Safety on the tour

This is always the top priority of all Oxalis Adventure tours to ensure the safety of both visitors and Oxalis’ staff on any trip. We only use high-quality equipment meeting international standards, mainly imported from France, the UK, and Switzerland. The guide team must undergo professional training and be tested for skills regularly. Only qualified Oxalis guides are allowed to lead Oxalis tours. Visitors can learn about the "safety management" and "safety equipment" that Oxalis uses here.

Risk prevention and management

Any adventure activities will always contain risks and these must be carefully managed. Oxalis tours take place in remote locations without easy access to medical care. Hence a lot of work goes into managing and reducing risks to the lowest level possible.

Preparation for the Hang Va Expedition

The Hang Va Expedition tour includes 1-night camping in the forest, so the items you need to prepare are quite simple. However, for a caving and camping tour in Vietnam, visitors will be asked to prepare suitable clothing for safety and comfort. Clothing should be good for trekking in the jungle, river crossings, or exploring the cave as well as avoiding dangers and risks from sharp rocks, snakes, insects, or poison ivy.

Long trousers and long-sleeved tops should be worn. Trekking shoes play a very important role in adventure tours like the Hang Va Expedition. Visitors need to choose a good, well-fitting pair of shoes for steep rocky terrain and they should not be waterproof, as during river crossings they will hold water inside. Besides, they also need to prepare personal items for 1 night’s camping in the jungle. The Oxalis tour consultant will give you helpful advice before joining the Hang Va tour in Quang Binh, Vietnam.

Hang Va Campsite

Located in a small valley next to the entrance of Hang Va Cave, this campsite is surrounded by primeval forest, where you can feel and touch nature, especially on moonlit nights, or waking in the early morning to the dawn chorus. The campsite is fenced with protective nets to prevent snakes from entering the camp at night. It is also located in a high valley which is not affected by floods. You must not go outside the campsite without your guide

Bathing at the campsite

Hang Va Campsite is in the middle of the forest 50m away from the cave entrance. Therefore there are no bathing facilities in the camp. Swimming and refreshing yourself can be done in the river passage inside Hang Va before you exit. However, no soap or shampoo is allowed.

Toilet at the campsite

For hygiene and conservation reasons, Oxalis has created eco-friendly toilets for our campsites, called "Oxalis Composting Toilets.".

The toilet consists of a normal toilet seat on top of a box. Inside the box, is a bucket and waste bag to collect all waste and toilet paper which is provided. Nearby is a container of rice husks. After finishing, cover the waste with a generous scoop of rice husks. This ensures a dry composting process, which does not smell, and covers the waste from insects.

When the buckets are full, the porters will change them and bury the waste in a designated location in the jungle. This will biodegrade and turn into fertilizer.

Visitors are required to use the composting toilets for both urination and defecation. Urination outside the toilet or inside the cave is not allowed because of the smell and impact on cave formations and the cave ecosystem.

Hand washing facilities are provided.
