Buckskin Gulch
Also known as the “longest slot canyon in the world,” Buckskin Gulch is one of the most treacherous hikes in the USA, if not the world. Because of the extreme danger of flash floods, trekkers must be incredibly careful on the trail. It’s 20.6 miles roundtrip, and can take upwards of two days to complete, depending on your trekking speed and schedule. If you do decide to head on this trail, make sure you’re well versed with the weather and any potential flash flood occurrences (Your Hike Guide).
