Son Doong Cave is located in the heart of the Phong Nha Ke Bang National Park in Quang Binh province of Central Vietnam. Only recently explored in 2009-2010 by the British Cave Research Association, Son Doong Cave has only been open to the public since 2013. Son Doong Cave has the largest cave passage in the world, and was only explored in 2009. Two large rivers, Khe Ry and Rao Thuong, join together to form Son Doong Cave. The cave follows a large fault line 100m wide, which contributes to the huge size of the passages. The Phong Nha Ke Bang limestone is around 400 million years old, but Hang Son Doong is less than 3 million years old.

The biggest adventure company in Asia – Oxalis Adventure, is based right here in Phong Nha – Ke Bang National Park and is the only official tour operator in the world allowed to conduct expeditions to Son Doong.

Son Doong Cave is a masterpiece of nature with otherworldly landscapes, enormous stalagmites and statuesque stalactites – hanging from the ceiling and rising from the ground like an alien species. The real jungle inside the cave will amaze you in every way, while misty clouds envelope the scene. The fossil passage will give you the opportunity to understand the formation of this ancient limestone.

Shoes that made it to the Son Doong Expedition

Trekking in Vietnam and especially on your Son Doong Expedition in Phong Nha – Ke Bang National Park will have you zoned into the beauty of Mother Nature in its true essence. Even though any physically active person with basic trekking experience can conquer this expedition, it is necessary to understand the fact that this is indeed a physically demanding and challenging journey. Choosing the right shoes will undoubtedly allow you to enjoy this expedition to the fullest!

1. High Quality Trekking Shoes

Carrying a pair of high quality trekking shoes is highly recommended while venturing into the jungle and caves on the Son Doong Expedition! Gore-Tex/waterproof boots are NOT recommended as they do not drain well. If you are comfortable with your own shoes, which are Gore-Tex, feel free to use them. However, it’s highly recommended to get non-waterproof trekking shoes with good grip that drain faster, as you’ll get to be part of lots of river crossing, wading and even swimming activities (optional) on the expedition; in a nutshell – your feet will be wet for the majority of the day! It’s best to find a shoe/boot with the softest and stickiest rubber sole, as this ensures the best grip.


We recommend using:

•   Salomon XA Enduro: This shoe has been designed to stabilize your feet on tough mountain terrain, while properly hugging them.

•   Salomon Speed Cross 4 boots La Sportiva X2: This shoe is highly cushioned, provides exceptional grip on all surfaces and is very lightweight.

•   Bestard Canyon Guide boots/shoes: These are considered to be one of the most ideal shoes for caving due to the terrific grip, durability and protected comfort.

We also advise you to consider bringing a backup pair of shoes.


2. Oxalis Basic Trekking Shoes

For travellers who don’t bring appropriate trekking shoes, Oxalis Adventure provides an option of using their jungle boots of basic quality for jungle trekking and river crossing. These are canvas style Cambodian Military boots that are quite rugged and considered suitable for jungle trekking. You’ll observe that these boots have been designed with two small openings to allow proper drainage of water during an arduous trek including lots of activity in the water.

However, with regards to an intense adventure tour like the Son Doong Expedition, it is not recommended to wear these boots into the jungle and cave for a duration of 4 days and 3 nights. The reason for this is the fact that the material of these boots makes them quite tight in the toe area along with the ankle area. On a long and physically demanding trek to the Son Doong Cave, you might develop painful blisters due to this. As mentioned above, Oxalis only offers these boots as an alternative choice for those without proper trekking shoes and these jungle boots come in 36 – 46 European sizes but please prepare trekking socks/densely-weaved socks or insoles to use with them to avoid blisters.

3. ‘Dep Ro’ – Plastic sandals

When you do this adventure tour with Oxalis Adventure, you’ll observe that the tour guides and porters don’t wear shoes. They wear locally designed plastic sandals known as ‘Dep Ro’. You’re bound to find yourself curious and concerned about this.

During busy season, the tour guides have to be on tour almost every other day of the month. In wet conditions, constant use of the same shoe for long durations can cause bad blisters, while these sandals keep the guides team blister free and comfortable even in the long run. ‘Dep Ro’ or plastic sandals require a fair level of getting used to. It is bound to be really difficult to feel a proper grip while getting over slippery surfaces in highly muddy conditions. In a nutshell, these sandals will only provide comfort and convenience in the jungle with regular use and being properly accustomed to wearing it.

We don’t recommend our adventurers to wear ‘Dep Ro’ during your journeys in any of our adventure tours especially Son Doong Expedition tour. Deciding to wear these sandals will actually put you at a higher risk of harming yourself while making your way across different challenging terrain, crossing rivers with strong current and even in situations where you’d have to boulder over rocks.

Among other skills that adventurers need, wisely deciding what to wear for a large scale adventure like the Son Doong Expedition is also highly important. So, before you arrive in Phong Nha – Ke Bang National Park for your exciting adventure, make sure you spend some time selecting the right shoes based on the information provided above!
