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 is the heartbeat of Oxalis Adventures. Born from extensive research into sustainable wildlife tourism, the Hang Ba Deep Jungle Expedition invites you into the strictly protected Core Zone of Phong Nha - Ke Bang National Park. This journey is designed for those truly passionate about nature, conservation, and the raw beauty of Vietnam’s caves.

You will trek through a unique limestone massif draped in ancient tropical forests that have thrived for thousands of years. This ecosystem is a sanctuary for rare and protected flora and fauna, offering a rare glimpse into a world untouched by time.

This expedition is not just a tour; it is the culmination of Oxalis’ decade of experience, developed in close consultation with UNESCO, the IUCN, and the National Park Management Board. Its excellence was recognized by Wanderlust Magazine (March 2025), which named it one of Vietnam's top wildlife destinations, specifically highlighting the unique opportunity for guests to review camera trap footage of the jungle's elusive inhabitants.

    The highlights include:

  • Explore 6 epic caves: Embark on a true caving expedition to uncover a remarkable chain of 6 pristine and colossal caves in the area, including Dai Cao Cave, Maze Cave, Hang Ba Cave, Vinh Dai Cave, Light Cave, and Vinh Tron Cave. Each cave presents its own distinct marvel, boasting a unique and breathtaking system of ancient stalactites and stalagmites.
  • Trekking under an ancient, primeval canopy: Experience the unique thrill of having almost the entire trekking journey unfold beneath the dense, protective canopy of the thousands-of-years-old primary forest in the core zone of Phong Nha-Ke Bang National Park. You will be immersed in a lush, vibrant ecosystem, shielded from direct sun, offering an unparalleled chance to fully explore the area's rich biodiversity and rare timber species.
  • Nature's symphony and immersive conservation: Awaken to a rare natural concert in the early morning, the resonant calls of gibbons and exotic birds echoing across the mountains, creating an atmosphere of unique serenity and grandeur. This tour is built upon a strong commitment to nature conservation, minimizing human impact, making it ideal for nature lovers seeking to deeply explore a rich and protected ecosystem.
  • Unveiling wildlife secrets via camera trap technology: Engage in a pioneering conservation tourism experience by observing the footprints and traces of rare jungle animals (such as civets, wild cats, deer, and antelopes) at their resting or foraging spots. Crucially, you'll get exclusive access to photos and videos from the specialized camera trap system installed by Oxalis, providing an authentic and non-intrusive look into the wild, hidden life of the National Park's core zone.
  • Spectacular, secluded campsites under the Milky Way: Enjoy an exhilarating camping experience at some of the most beautiful and isolated campsites in the tour system, often situated right at the mouth of vast caves (like Dai Cao cave and Light cave) or beside a cool jungle stream. These carefully chosen spots are far from wildlife habitats and free from light pollution, allowing you to gaze at the moon, stars, and even the Milky Way with incredible clarity.
  • Ultimate digital detox and authentic challenge: The entire journey is completely disconnected from phone signal and Wi-Fi, allowing for a full "Digital detox" to focus entirely on the wilderness experience. Rated at a high difficulty level (Level 6), this is a genuine challenge that demands excellent fitness and trekking experience, featuring activities like steep climbs and demanding cave exploration, delivering the profound satisfaction of becoming a true adventurer.
  • Exclusive privilege: With a small, elite group size of only 6 guests per group, this expedition offers a truly exclusive and personalized experience. The limited number of guests not only ensures the highest quality of service and absolute safety, but also directly and meaningfully contributes to the biodiversity conservation efforts within the World Natural Heritage Phong Nha - Ke Bang National Park. Guests are not only explorers but also companions in the conservation mission in the deep forest core.

Phong Nha – Deep Jungle Trek – Dai Cao Cave

Your journey begins between 07:30 and 08:00 with a pickup from your Phong Nha hotel. At the Oxalis office, you’ll receive a safety briefing, sign release forms, and pack your gear. On the way to the trailhead, we stop at the Wildlife Rescue Center to see how the National Park rehabilitates rescued animals for release. The bus then drops you at KM 23 on Victory Road 20, deep within the park.

The expedition kicks off immediately with a steep uphill climb. The route covers 3 km of mostly uphill terrain before descending through dense primeval forest, home to ancient trees and rare wildlife. Be prepared for a challenge: the path includes steep rocky sections with gradients exceeding 45 degrees. We will stop for a jungle lunch surrounded by nature.

By mid-afternoon, we reach the exit of Dai Cao Cave, where your guide will point out animal tracks on the cave floor. Equipped with life jackets, you will swim through the cave’s tall main passage. Keep an eye out for unique white fish and shrimp adapted to life in total darkness.

After exiting the cave, we settle in at the Dai Cao Campsite. Dinner is served at 18:00. Spend the evening relaxing, stargazing, and swapping stories before falling asleep to the sounds of the jungle.

Hang Ba – Circle Lake – Light Cave Campsite

Wake up at 5:00 AM to enjoy tea and coffee by the stream. For early risers, this is the perfect time to observe animal tracks and listen to the morning chorus of birds and monkeys echoing through the mountains (this activity is optional). After breakfast at 8:00 AM, we pack up and head to Maze Cave. A 30-minute swim and trek leads to the first entrance, where you will discover stunning cave formations, ancient fossils, and shafts of sunlight piercing the darkness. Your guide will also point out diverse wildlife footprints along the way.

We return to the campsite for lunch before beginning a 2 km trek through the forest, passing ancient trees and scrambling over rocky terrain to reach Hang Ba. This massive cave features three distinct exits and a stunning emerald underground river—a photographer's dream. Exiting Hang Ba reveals the breathtaking Circle Lake, surrounded by sheer limestone cliffs. We cross the lake to reach our evening destination.

Tonight’s camp is set inside Light Cave, a unique site framed by two magnificent stone arches. Dinner is served at 18:00. Spend the evening relaxing in the cave or stargazing at the Milky Way through the arches—an unforgettable end to the day.

Circle Lake Cave – Wildlife Tracking – Vinh Dai Cave

The day begins before dawn at 05:00 AM. We paddle out onto Circle Lake to enjoy tea and coffee while listening to a unique jungle concert—the sounds of the forest waking up. As the light grows, scan the sandy banks for fresh animal footprints left during the night. After breakfast at 08:00 AM, take time to relax at the Light Cave camp. The morning sun illuminating the twin cave entrances offers spectacular photography opportunities.

Leaving the camp briefly, we climb the steep hill above the lake to explore Circle Lake Cave. With a massive 90m-wide entrance, this cave is a haven for local wildlife. We will inspect the camera traps set up here, explore formations deep inside, and hopefully witness sunbeams cutting through the darkness. We return to the campsite for lunch.

The journey continues with a scramble over a rocky exit passage, followed by a swim (or trek) along the river to reach Vinh Dai Cave. After settling into the new campsite, we gather for a unique activity: collecting memory cards from local camera traps and reviewing the footage to see what wildlife has passed through recently. Afterward, explore the main passage of Vinh Dai Cave for more stunning photo ops.

Dinner is served at 18:00. For your final night, we move just outside the cave to relax under the open sky. Listen to the jungle nightlife, watch the stars, and reflect on the journey so far.

Vinh Dai Campsite – The Final Ascent – Phong Nha

Enjoy a hearty breakfast and the tranquil mountain air before preparing to conquer the final towering peaks.

Important: As there are no water sources along the trail today, you must prepare and carry at least 2 liters of water before leaving camp.

The day begins with an intense, steep hike straight out of the campsite. For the first hour, you will navigate sharp, rocky terrain requiring scrambling and climbing. In the most difficult sections, our safety team will assist you using harnesses and ropes to ensure a safe ascent.

Once we clear the rocky section, the terrain becomes easier as we continue uphill. We stop for a light lunch on the trail before beginning the final descent. Depending on the group's pace, we expect to emerge from the jungle at KM 23 on Victory Road 20 between 14:30 and 15:00. An Oxalis bus with cold beverages will be waiting to welcome you back to civilization. Celebrate your achievement with a medal recognizing the completion of Oxalis' most challenging expedition before the bus transfers you back to Phong Nha around 16:00.

The highlight of this Oxalis tour focuses on wildlife conservation, whilst at the same time showing customers the activities and kinds of animals living in the National Park, without disturbing them or their activities. Oxalis has also learnt that ecotourism activities will deter local hunters and loggers, creating even more protection for these endangered species.

Guests who book the Hang Ba tour will be advised to exercise, gain physical fitness, and participate in outdoor trekking/hiking/camping activities in order to be fully prepared for the expedition. Good fitness will enhance the enjoyment of the tour. Whilst the tour is physically challenging that is not the aim of the trek. Guests participating in the tour must be nature enthusiasts as they will spend a lot of time contemplating nature, temporarily disconnected from computers, the internet and phone calls.

Hang Ba Deep Jungle Expedition Tour is designed so that the duration and difficulty of each day is more or less the same.

April and May are the warmer months, and this is the time when wildflowers are blooming.

Toilet at the campsites

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.
