Bootleg Canyon Mountain Bike Trail, Boulder City, Nevada
These trails can seem almost unrideable, so extra precaution is very much needed. Advanced skills are required with some of the downhill trips, and it has steep sections and drops not advisable for the weak of heart.
Black Mountain, Brevard, N.C.
Black Mountain in Pisgah National Forest, Brevard North Carolina has one of the most scenic trails complete with beautiful waterfalls. But this ride isn’t for the weak of heart (and skills). Insane jumps, crazy switchbacks, and downhill drops that require some serious ability to control your bike.
