Hang Ba Deep Jungle Expedition

This expedition takes you to discover six incredible caves, including Dai Cao Cave, Maze Cave, Hang Ba Cave, Vinh Dai Cave, Light Cave, and Circle Cave. It is the best chance to catch a good view of the Milky Way and the Moon with your own eyes, enjoy the dark skies filled with stars and unpolluted by lights.

Conservation has always been a top priority for Oxalis Adventures. After some research into wildlife tours, Hang Ba Deep Jungle Expedition was born. This is a tour to the core zone of Phong Nha - Ke Bang National Park, for those who are passionate about nature, conservation, wildlife and exploring caves in Vietnam. The area is home to many rare and protected animals, and plants. This unique limestone massif, covered by an ancient tropical forest thousands of years old, is home to many caves for those who are interested in cave exploration.

The Hang Ba Deep Jungle Expedition Tour is a completely new product, based on Oxalis’ 10 years experience in adventure tourism and conservation together with comments and advice from UNESCO and IUCN representatives in Vietnam, and members of the Phong Nha - Ke Bang National Park Management Board. Below are some special features of this tropical forest tour.

  • Differing from all other existing Oxalis Adventure tours, the Hang Ba Deep Jungle Expedition leads you through an ancient primary tropical forest where almost 95% of the route is under the tree canopy.
  • Only on this nature discovery tour, will guests be able to participate in early morning activities to immerse themselves in nature. Listen to the early morning chorus of birdsong as a signal of a new day, combined with the calls of monkeys echoing around the jungle.
  • Experience 3 campsites just inside and next to spectacular cave entrances, with amazing views, and cool in summer and warm in winter. Campsites are all away from the areas of wildlife activity, so that humans will not disturb the animals.
  • For the first time, Oxalis Adventures will take customers to see the habitats of many wild, rare and protected animals in Phong Nha - Ke Bang National Park. You will have the opportunity to observe the footprints and other traces of wild animals such as Mountain Goat, Deer, Wild Boar, Gibbons, Langurs, and Wildcats. Moreover, Oxalis has installed many camera traps throughout the tour. Activated by movement, these cameras will record the day and night time activities of wildlife. Images and videos will be downloaded onto a tablet for guests to view. Observing animals in this way means we will not disturb the normal activities of the animals, or drive them away from their natural habitat.
  • This is a trek where customers will become real cave explorers. This cave exploration tour will enable you to discover six amazing caves such as Dai Cao Cave, Maze Cave, Ba Cave, Vinh Dai Cave, Light Cave and Circle Bay Cave. This Vietnam cave tour is the first tour to visit these caves since their original exploration in 1992 and 1994.
  • Camping in the deep jungle where there are no lights, provides an opportunity for guests to observe the stars, moon, and perhaps the milky way unimpeded by artificial light. This is also a rare chance for those living in big, bright cities to enjoy a truly natural dark night. Hang Ba expedition Tour porters, guides, and chefs have undergone training on how to limit unnecessary noise and disturbance whilst working. By running forest expeditions in this area, Oxalis also helps to reduce the hunting or illegally logging actions of local people.
  • This jungle expedition tour of 4 days and 3 nights leads you deep into the core zone of Phong Nha - Ke Bang National Park with its challenging steep hills, sharp rocky terrain and natural caves, which is why you need to be well-prepared physically and with the correct clothing and equipment.
  • With a maximum of 6 customers per group, this special expedition will bring customers the best experience and at the same time make an important contribution to the conservation of biodiversity within the world heritage site of Phong Nha Ke Bang National Park.

Good fitness will enhance the enjoyment of the tour. Whilst the tour is physically challenging that is not the aim of the trek.

Weather and climate in Phong Nha - Hang Ba

Phong Nha - Hang Ba area has 4 seasons in a year (spring, summer, autumn and winter) like many northern provinces of Vietnam. Due to the weather conditions, and because Oxalis Adventure wants to protect and conserve the area, the Hang Ba Deep Jungle Expedition will only be available from February to mid-August every year. Weather conditions in the area are different in each season.

From January to March, there are many cold days, especially on rainy days but there are also many warm sunny days. April and May are the warmer months, and this is the time when wildflowers are blooming. From June to August are the hot summer months, but most of the time visitors are in the cave with the temperature from 22 to 25 degrees, or forest, so it should not feel too hot. In these summer months, visitors can also comfortably swim inside the cave. All of the camps are located inside caves so customers do not have to worry about rain or heat at the campsites.

Each season has its own unique features for visitors to explore and learn more about the area. In addition, guests can check the weather in Phong Nha through the Accuweather to have the best preparation for the Hang Ba Deep Jungle Expedition tour.

The tour is mostly on jungle trails, hiking up and downhill many times, and there are no paths for bicycles, motorbikes or cars. The entire journey will have no phone signal, no wifi and no other amenities as in a hotel.

Each Oxalis Adventure tour is equipped with a satellite phone for the tour guide to contact the Operations team in the event of an emergency or incident.

While trekking in the mountains and exploring the caves, the safety team will communicate with each other by walkie-talkie if required.

The specialized equipment is imported from abroad and complies with European standards. Due to the remote location, rescue teams and medical assistants will take from 30 minutes to 2 hours to reach the location.

Campsites on the tour

All of the campsites on Hang Ba Deep Jungle Expedition tour are arranged inside the cave entrances. The special thing about this tour is that all of the most beautiful places such as by the lakes, next to the river or stream are left untouched so that human activities will not disrupt the habits of wild animals in the area.

On the first day of the journey, visitors will camp next to the entrance of Dai Cao Cave following an exciting swim through the cave in cool water after a long day’s trekking. The campsite is located at the entrance of the cave, next to a stream. Enjoy the food prepared by the chefs, listening to the murmuring stream, and bird and jungle sound. Guests can also see the stars and milky way after dinner whilst sipping a cup of hot tea or coffee.

Finishing day two, Light Cave camp is a great camp, possibly the most special camp on the trip because it is located in the middle of Light Cave. Whilst having dinner or chatting at the campsite guests will see the amazing view of the two cave arches, one on either side. The next morning, the sun will shine into the cave via the cave entrance, creating a magical scene. Enjoying breakfast and sipping a cup of coffee in front of the wonderful view from the Light Cave camp is a great way to start a new day.

The last camp in the journey is Vinh Dai Cave campsite located near the cave entrance. Vinh Dai Cave campsite is an exceptional camp, situated on a balcony overlooking the tall river passage, and with a great view of the entrance and jungle beyond. In the evening and early morning looking out of the entrance and seeing the mist on the jungle-covered mountains is amazing.

On the second night, visitors will be taken by a guide to Circle Lake, bringing with you binoculars provided by Oxalis to try to observe nocturnal animals. The team will be asked to stay quiet, put the lights on the lowest level, and move cautiously so as not to disturb any animals.

Toilet at the campsites

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

The toilet is inside a tent, and 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 fertiliser.

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.
