Crystal Ridge Trail, Washington
You don’t need a pass and the trail is both diverse and challenging. It runs a total of 9.1 miles, but there’s a forest service road that will let you exit halfway through if you prefer.
Be warned, the second half of the trail can get dicey. Experienced drivers who frequent this trail warn newbies to get our of their rigs to look at what’s ahead before it’s too late. Certain places along the trail make for an easy roll over.
