Here’s what it’s like to camp inside the world’s third largest cave – Hang En, Vietnam

“Nothing really compares to waking up and having coffee in the mouth of an enormous, beautiful cave with thousands of birds overhead”   

~ An adventurer after visiting Hang En

Hang En is the third largest cave on Earth and is based in the heart of Vietnam; the Phong Nha – Ke Bang National Park. Currently considered to be the 3rd largest cave in the world by volume after Hang Son Doong and Deer Cave in Malaysia, Hang En is certainly one of the most prominent and impressive caverns on the planet. This 3 million year old wet cave was carved out by the powerful Rao Thuong River as it cuts its way through the Annamite Mountains.

Deep in the Phong Nha – Ke Bang National Park, local tour operator Oxalis Adventure conducts expeditions to Hang En that span over 2 days and 1 night. The Hang En 2 – Day Adventure is considered to be one of the best adventure tours, not just in Vietnam or Asia, but all over the world primarily because of how amazing the camping experience is. Read on to find out what’s so special about it!

Is the Hang En campsite inside the cave?

You would’ve guessed by the title that the campsite of Hang En is actually located inside it and you’re not mistaken at all to deduce so. As mentioned earlier, the Hang En cave is nestled deep inside the Phong Nha – Ke Bang National Park and hence you can be sure to have all the tranquility you seek while you’re in the lap of Vietnam’s wilderness.

One of the main factors that make the Hang En adventure one of the most unforgettable experiences in the world is the fact that you actually get to camp inside the cave. You would want to imagine sleeping inside the third largest cave on the planet, surrounded by an exceptional show of nature’s might and beauty and enjoy your life at its best. On most cave expeditions and adventures, the campsites are often set close to the cave’s entrance or a couple hundred meters away; the Hang En campsite, on the other hand, remains unique with its unconventional location and is sure to charm you in every way!

It’s a world within a world!

You will be entering Hang En through a broad slit in the cliff and wander through the mystical passageway towards monstrous boulders; the trail weaves its way to a high point as penetrating sunlight illuminates the way forward; you will then climb over one last peak rewards you with the breathtaking view of your campsite inside the cave – A wide, sandy beach fringing an aquamarine lake completely engulfed by the enormous cave. This is what the social media would truly call #TravelGoals!

When you’re welcomed into the world of Hang En, you will not just be awe-struck by the cave’s beach campsite, but also the mammoth size and surroundings. It would interest you to know that Hang En is also popularly called the Swallow Cave, as it is home to thousands of swallows that you will hear adding to the symphony of nature when you’re there. The gigantic formations, the massive ceiling, the soft sands and the drop-dead gorgeous lake next to your tent and the sounds of Hang En will truly enrapture you.

Shall we go for a swim? 

Like we have mentioned above, one of the biggest highlights of the Hang En campsite is the fact that you get to enjoy a private natural pool as and when you feel like. You will adore sitting on the sandy banks of the azure lake inside the cave or swimming in it completely, as you don’t get have these kinds of experiences every day in life.

Don’t be afraid if you’re not a swimmer, you will be given a buoyancy aid and the Oxalis Adventure tour guides and safety assistants will make sure you’re safe under all circumstances. So when you’re at the Hang En campsite, be one with the cave’s beach, soak up some sun and enjoy a dreamy dip!

You’re in for a feast!

Once you trek your way through the dense jungles of the Phong Nha – Ke Bang National Park and make it to the massive Hang En, your stomach would surely want to be rewarded with a filling meal and the Hang En campsite will certainly not disappoint.

On all tours of Oxalis Adventure, you will be treated to some of the best food you’d have had through all your travels across Vietnam. The porters and chefs who carry your luggage through the jungle at astonishing speeds, arrive at the campsite much in advance on the day of the tour. In the campsite’s kitchen area, they prepare food with the highest standards of hygiene and professionalism; the chefs always cater to the food preferences of the guests.


So, when you have the Hang En camping experience, you won’t have to worry a bit about the food whether you’re a vegan, vegetarian, meat lover or have any specific allergies, as the impressive variety of the dishes will be served keeping your convenience in mind. At the campsite, every meal is freshly cooked with the perfect ingredients to recharge your adventure struck body for the rest of the journey on day two. Apart from the meals, you will also be provided with a very large quantity of refined drinking water, coffee, tea and snacks that you can enjoy at the campsite’s dining area.

After an incredible day, it’s time to sleep.

Nature’s calling?

Just like the rest of the campsites of Oxalis Adventure, the Hang En campsite also comes with modern-style composting toilets.

These composting toilets at the campsite have been structured and built very well and are strategically placed in the campsite, at the most appropriate distance from the sleeping tents, dining area and kitchen. After making use of the clean toilet seat, you will be using rice husk to cover as a replacement to water flushing; the rice husk drastically minimizes the smell and in some months, turns into a fertilizer. The composting toilets come equipped with toilet paper, hand sanitizers and room fresheners to give you the best toilet experience possible deep inside the wilderness.


Home away from home

The level of beauty, comfort and convenience you’ll feel at the Hang En campsite is bound to make you feel like it’s a home away from home; a home for your adventurous soul! Besides the kitchen, composting toilets and sleeping area, you will also find a changing tent, where you can comfortably change and put on fresh clothes for the rest of the day.

This cave is considered the second largest cave in Vietnam and third largest in the World, and it also makes up one night of the original five-day Son Doong Cave Expedition being so close to the largest cave in the world. It includes visiting Ban Doong Ethnic Village, located in the jungle, and a magnificent campsite on a sandy beach inside the cave. It includes 22km of jungle trekking at times quite rocky, multiple knee-deep river crossings, and elevation change of 400m (the ‘hill’ you won’t forget), and 4km of caving.

It involves rock scrambling, wading through an underground river, bouldering and rope-traversing within the cave, to reach the rarest tower cone formations.

It is not for the faint-hearted, but still only considered level 3 adventure level compared to level 4 of the Hang Tien 3-day tour. It costs VND 8,000,000 per person (USD 348).

• Hang Tien Exploration – 3 DaysThis three-day tour stands out for combining a taste of Tu Lan with some river cave swimming, before crossing a mountain range to reach the valley for Hang Tien – the most astounding dry caves in the region, where you will enjoy trekking, bouldering over various rocky terrains to witnessing breathtaking patterned calcite walls & ceilings of Hang Tien.
