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).
