Hang En Cave Adventure
The journey 2 days 1 night Hang En Adventure brings customers to the fairyland in the Hollywood movie (Pan: The Neverland 2015), and where ABC News made the live broadcast for Good Morning America program. Hang En cave is part of the famous Son Doong expedition tour.
Hang En Cave is one of the largest caves in the world, located in the core zone of Quang Binh’s cave kingdom, Phong Nha - Ke Bang National Park, Vietnam. Trekking tours to discover En Cave with Oxalis Adventure will bring visitors to an exciting night’s camping inside a majestic cave which is 3 million years old.
The cave was discovered and reported in 1994. Impressive images of this Vietnam cave quickly became well-known and attracted attention all over the world. Hang En was praised by the world's largest travel magazines such as National Geographic Magazine, The New York Times, and Lonely Planet. 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.
The Hang En discovery tour is also a part of the world-famous Son Doong Expedition. On the first night of the Son Doong tour, the cave camp will be set up inside Hang En. Domestic and international travelers have high praise for the Hang En trekking tour in Quang Binh. Some even regard it as one of the most attractive adventure tours of Oxalis Adventure. The unique features of the trip are:
- World's Most Unique Campsite: Hang En's campsite is located in the middle of the cave, where there is a cave entrance above. The floor is a wide sandy beach with a beautiful emerald lake, and a part of Rao Thuong river flowing through it. The cave camp receives light from the cave entrance. Particularly from December to the end of February, in sunny weather, sunbeams will shine deep into the cave campsite in the morning, brightening up the whole cave, and creating a spectacular scene.
- Swim in the unique emerald coloured underground pool: The campsite has cool water flowing from an underground cave so the temperature of the water in the lake is about 17 to 25 Celsius degrees (63F - 77F). Warm in winter and cool in summer. Meanwhile, the water flowing next to the lake from the entrance brings warm water from the valley outside into the cave.
- Giant cave: Hang En has a length of nearly 1.6 km. The Rao Thuong River passes through Hang En on its journey to Son Doong Cave. The cave has three entrances: the river entrance, the high main entrance and the large exit. At the campsite the width of the passage is around 200m, and the highest point in the ceiling is 140m. Hang En is currently one of the largest natural caves in the world.
- Trekking through primeval jungle: Hang En is located in the core zone of Phong Nha - Ke Bang National Park, where there are ancient trees thousands of years old. On this adventure trek, 70% of the time visitors will walk under the shade of the primary forest.
- Experience Doong Village: Visitors who join the Hang En caving tour will have a short stop in the Doong village of the Bru Van Kieu people. At this village, visitors can learn about the lifestyle and culture of the villagers; visit the village's school, stilt houses, and have lunch at one of the houses of the residents in the village.

Bathing at the campsite
Hang En campsite is located next to a natural lake inside the cave, the lake has a fine sandy beach and next to it is a stream that flows through. On summer days, the water at the lake is cool so that the guests can swim happily, while the water from the Rao Thuong Stream is somewhat warmer because it flows under the sun for a long time. For conservation reasons, shampoo and soap are not allowed to be used at the campsite. Visitors are advised to use dry shampoo if necessary.
Toilet at the campsite
The tour occurs in a remote jungle with no power or infrastructure and for conservation and hygiene Oxalis has created environmentally friendly toilets, 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.
