Smackdown is hardest to find, but is identifiable by a 100 foot granite slickrock. OHV and Cultus Mountian. Good short trails for good hardcore riders. Riding the Slickrock is fun and something different for Washington. Ride at your own risk, and have lots of fun.
Rides are best if done in laps for added endurance and fun.
Near the end of the day we found the smackdown. There is one trail toward the parking area that looks fun. So, i give it 2 flat tires cause if you live less than 50 feet away then it is worth it, but if you live any farther consider riding in your backyard and build your own stunts. Don't know how I got there. Spent about an hour and a half looking for the trail.
