Land Owner
Don't let the distance fool you. This is a very tough ride. There are lots of drops, switchbacks, and plenty of exposure tot keep you on your toes. Plus about half-way into the ride there is a fairly long hike a bike section. That all being said this trail is a blast and has everything an All-Mountain rider could ask for. Most link a few of the other trails above or below for an awesome day of shuttling.
