The last part of the trip is the scariest part of Angel's Landing. The hike is five miles round-trip and has cliff drops and switchbacks. For the last few hundred feet, hikers need to use a metal chain to move through a tight passageway.
Mount Rainier is not easy to reach the top of. For many people, the walk is worth it because of the view. The hike is also dangerous because of things like cold, avalanches, slick rocks, and falls.
Crawler's Ledge, a narrow ledge of about one to two feet that walkers have to squeeze through while watching the waves of the Pacific Ocean hit the sides of the mountain, is the worst part of the hike.
Hypothermia is a big risk on Mount Washington, where the wind can blow up to 200 miles per hour and the temperature drops 40 degrees from the base to the top.
Trekkers going through The Maze in Canyonlands National Park should be afraid of flash floods, getting too thirsty, and rocks falling on them.
Bright Angel Trail is in Grand Canyon National Park. People who don't do well in the sun shouldn't go there. The hike doesn't have much shade, but there are a lot of turns.
The steep and narrow road goes along the side of the mountain, and hikers must use the metal rungs sticking out of the cliff to climb up the side of the mountain.

The Devil's Path trail goes through the Catskill Mountains for about 25 miles. The level of elevation changes often, which makes the walk both physically and mentally hard.
