Hang Tien Endeavor Tour

Hang Tien Endeavor Tour is a challenging adventure tour, where guests will explore two largest dry caves of the Tu Lan System, Hang Tien 1 & 2. They are well-known for giant stalactites, and big cave passages, the tour also includes one night camping.

Hang Tien is the largest dry cave in the Tu Lan System, and is located in Cao Quang Commune, Tuyen Hoa District, Quang Binh Province, Vietnam. This is about 70 km from Phong Nha – Ke Bang National Park. Hang Tien is famous for its natural beauty with special cave formations such as gour pools.

The unique features of the trip are:

  • Explore: Fun Cave, Tien 1 and Tien 2 Caves - the final caves of the Tu Lan Cave System. Discover the impressive and unique cave ceiling dome, the large gour pools – a special kind of cave formation resembling rice terraces, and many stalactites.
  • Experience the "flying fox" inside Hang Tien 1: a safety system used to cross the stream in case of high water (normally crossed by walking). This is an impressive experience for most visitors of the Hang Tien Endeavor Tour.
  • Hang Tien Campsite: one of the dreamiest campsites next to the river with stunning views. Enjoy the “natural infinity swimming pool” where the underground river from Tu Lan wells up right next to the campsite. This is a lake beneath a small limestone cliff, formed naturally with an “infinity view” as described by many guests. Do not ignore this opportunity in this tour - Hang Tien Endeavor.


The itinerary of exploration tours can be changed due to weather conditions. The jungle trail during the exploration trip can be quite muddy and slippery when it rains.

Phong Nha - Tan Hoa Commune - Fun Cave - Tien Cave Campsite

From 07:30 to 08:00 AM on the departure day of Hang Tien Endeavor Tour, the tour guide and driver will pick you up at hotels around Phong Nha town to drive to Tan Hoa Commune for the safety briefing and packing. After signing the Release form, you will receive the necessary safety equipment and set off for the caving tour.

After warming up with an ascent of a small hill, you will overcome some rocky terrain, and trek downhill to a small valley, there will be a short steep peak to conquer before reaching Fun Cave – an interesting dry cave also known as a “warm-up” cave in this caving and jungle trekking tour. You will also stop at the other end of the cave for a picnic lunch prepared by our porters. After Fun Cave, you will carry on down to Hang Tien campsite, where it is time for you to have a break, enjoy the scenery and get ready for a swim at a “natural infinity swimming pool”. Enjoy a cool bath surrounded by beautiful scenery before returning to the idyllic camp for a hot cup of coffee or tea before sunset. A delicious dinner will be served soon by the amazing porter chefs. You may linger after dining or return to the tents for a comfortable night.

Hang Tien 1 & 2 - Phong Nha

After breakfast at the camp, guests continue to walk through the jungle and over a very rocky path to reach Hang Tien 1. You will be amazed by the vast entrance with a high roof, and tall calcite formations covered with plants and mosses. Marvel at the circular ceiling dome inside. At the end of Hang Tien Cave, you will be equipped with safety harnesses to climb up a 10m high ladder, leading to the cave exit. After about 30 minutes of trekking through the forest from Hang Tien 1, you reach Hang Tien 2. Pass through a small entrance and spiral down to a huge passage, containing a floor of fine terraces, cave pearls, and many formations.

Finishing Hang Tien 2, guests return to the entrance to have lunch and then conquer a rocky 300 meter high mountain before dropping down to the pickup point. Back at Tan Hoa office, there are plentiful showers (hot and cool) to refresh you; take a rest with a cold drink or have a look at Tu Lan Lodge - a newly built accommodation for 3 or 4 day tours to Tu Lan and Hang Tien.

The tour guide and driver will bring you back to Phong Nha town at around 7:00 to 7:30 pm, completing the Hang Tien Endeavor, a Vietnam adventure tour to explore the large dry caves of the Tu Lan Cave System.


On heavy rainy days, the water may turn brown with a strong current.

Then, the group will return to the homestay for a restful night.

Weather and Climate in the Tu Lan - Hang Tien area

The Tu Lan - Hang Tien area has 4 seasons in a year (spring, summer, autumn, and winter). Due to the weather and for conservation, Hang Tien Endeavour tours are only operated from November to the end of September yearly.

  • From December to March the weather will sometimes be cold interspersed with sunny days.
  • April and May are spring months with cool air.
  • From June to August, are the warm months of summer. However, most of the time visitors trek under the forest canopy or inside the cave with a temperature of 22 to 25 degree Celsius. This is also a perfect time to enjoy the “infinity swimming pool” near the campsite.

Each season has its natural features to enjoy, and visitors can check the weather at Hang Tien or Tu Lan via Accuweather before joining an Oxalis Adventures caving tour.

They will be asked to have appropriate clothing for safety reasons, good for moving in the jungle, river crossing, or exploring the cave as well as avoiding dangers and risks from sharp rocks, snakes, insects, or poison ivy.

Visitors must choose a good and well fitting pair of shoes for rocky steep mountains and should NOT buy waterproof footwear for river crossings as they will retain water.

Travel safety tips

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.

You can learn more about "Adventure Safety Tips" here.

Campsites in tour

This is considered to be one of the most beautiful campgrounds that Oxalis has, located right on the riverbank, and also the point where the underground river emerges, on its way to the sea, creating the amazing “natural infinity swimming pool”. The campsite in the valley has open views allowing visitors to contemplate the clear blue sky, millions of stars or the colorful dawn.

The average temperature in winter is about 15 to 18 degrees Celsius, and in summer it is from 30 to 38 degrees Celsius. Guests will be provided sleeping bags and warm mattresses for winter and solar-powered fans for summer. More information about the "unique campsites in Tu Lan Cave System" - camping inside Quang Binh forest is available here.

Bathing at the campsite

The campground on Hang Tien Endeavor Tour is located next to the river and pools so guests can swim here. All swimming activities are supervised by safety assistants. Soap and shampoo cannot be used in the rivers and pools. At the campsite are water storage tanks to store clean water for drinking and cooking. During heavy rain the river may turn brown and muddy. For conservation reasons, visitors must use bio-shampoos and soaps. Washing should be done at the campsite and not in the river.

Toilet at campsites

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.
