The 20 Most Challenging Hikes in America, Ranked

8.Backpacking in The Needles, Canyonlands National Park, Utah

Difficulty: Class 3

The Needles presents one of the toughest backpacking experiences in the U.S. with extreme heat, limited water, and demanding terrain. Hikers navigate a maze of slot canyons, rock formations, and tricky scrambles, making this a truly isolated adventure. Water management is essential—carrying over 6 liters per day for hydration is necessary, especially in the hotter months.

The trail length varies, up to 25 miles, with elevation gains of up to 3,500 feet. Permits are required and typically available as walk-ups. The challenge comes from carrying large amounts of water and navigating exposed terrain, which pushes endurance and survival skills to the limit.
