Starts out with a killer hard fire road climb out of Bordeaux campground - the first two miles are pretty rough. The climbing gets more gradual, but rougher as you turn into the North Rim trail. After about 5-6 miles of gradual, rolling climbs over rocks & roots, you are rewarded w/ a smooth 4 mile descent w/ many switchbacks and some nice berms (motorcycles share these trails).
How to get there:
Take I-5 South from Olympia. Turn on the Little Rock exit. Follow the road through Little Rock until you run into Waddell Road; turn right and follow until the road ends (Bordeax Campground - which isn't used anymore, but you can park there).
The WA State Dept. of Natural Resources has maps of Capitol Forest for a buck or two.
