Kota Kinabalu

Located in Borneo, an island in Malaysia, Kota Kinabalu offers trekkers the ability to hike to the highest peak in Borneo. Despite the achievement on this UNESCO World Heritage Site, it’s still one of the most treacherous hikes in the world. It has diverse flora and fauna and is a very difficult hike that requires a lot of skill from hikers, who must be in good shape. At the top, you can even climb a vertical wall while attached to a steel cable (Book A Trekking)

Annapurna Circuit

Another trek located in Nepal is The Annapurna Circuit. Even though it’s one of the most stunning hikes in the world, it’s also one of the most treacherous. Narrow trails alongside steep cliffs make it incredibly dangerous. The trail is also prone to landslides and avalanches, especially later in the day. The pass, located at 5,416 meters, is where trekkers might experience altitude sickness. Despite the toughness of the trail, the view of the Himalayas makes it an incredibly spectacular experience. If you do decide to attempt this trek, make sure you have plenty of gear and keep an eye on trail conditions (Intrepid Travel).

Pamir Mountains

Central Asia is home to some of the most spectacular, undiscovered scenery in the world. If you want a unique experience and a trail all to yourself, you’ll find it in Central Asia. The Pamir Mountains has some of these trails, albeit some of the most treacherous ones in the world. You’ll be at the “Roof of the World” with some of the harshest conditions on planet Earth. Rapidly changing weather conditions makes it very dangerous. The mountains reach up to 7,000 meters high Trekkers may experience altitude sickness if they trek above 3,000 meters. These mountains are the third highest in the world, so trekkers beware of the dangers that come with high altitude trekking (ntripping).

Mount Rinjani

Trekking an active volcano is on every adventurer’s bucket list. Even though Mount Rinjani looks appealing because of this, it’s still one of the most treacherous hikes in the word. It reaches up to 3,726 meters high and is the second highest volcano in Indonesia. It’s located on Lombok Island. Indonesia sits on the “Ring of Fire,” which means it’s home to numerous amounts of the world’s volcanoes. People love taking risks and playing with fire, but if you do decide to hike this trail, make sure you’re aware of the volcanic activity beforehand. Hiring a guide is also extremely recommended (The Athlete Blog)

Fansipan Mountain

Fansipan Mountain is notorious for its danger. In 2016, 22-year-old Adrian Webb was found dead on the mountain, at 2,800 meters, only a few hundred meters below the peak. There are several routes to the peak, but he attempted the most treacherous one. He attempted to climb a new route, which is one of the reasons this trail is so dangerous. Unfortunately, he’s not the only trekker that’s died on the mountain, a 20-year-old student from Hanoi also died when he went missing in a portion of the trail with precipitous cliffs (Two Birds Breaking Free).

Tiger Leaping Gorge

The Tiger Leaping Gorge trek is in China and offers gorgeous views of vertical cliffs and a turquoise waterway, with a view of Snow Dragon Snow Mountain. It’s a captivating hike that’s caught the attention of trekkers for many intrepid travelers. It takes about three days to safely complete the hike. It’s recommended to not attempt to complete this trail alone, and to take as much time as you need to safely complete it (NOMADasaurus).

Lesotho’s Drakensberg Traverse

The final treacherous hike on this list is Lesotho’s Drakensberg Traverse, located in Africa. Trekkers leave from Johannesburg, South Africa, and drive through plains and low ridges in order to end up at the trailhead. The climb itself is straightforward, but the famous chain ladders at the final section of the climb makes it quite dangerous. Trekkers must be fully and completely aware of their footing, so they do not mistakenly miss one of the rigs and fall to their demise (Mountain Life Media).
