Access this trail from either via Corrals trail from either Bogus Basin Road (shorter), or 8th Street.
At the start, turn north onto Hard Guy from Corrals trail and drop down a short distance into a drainage. After the short drop, start cranking! It's a sustained steep climb all the way up to the Boise Ridge Road.
To descend you can either reverse your tracks (steep and fun, but not very technical), or you can come down any number of other trails that leave from the Boise Ridge Road; Dry Creek
, 8th Street Motorcycle Trail, and 5 Mile Gulch to name a few.
