I did this Capitol Forest Loop hike after an invite from my friend Craig. Craig wanted to scope out some of the trails in and around the Capitol Forest near Olympia for one of his upcoming urban trails books that he is currently working on. Capitol Forest has many miles of trails. Unfortunately (or fortunately depending on what user group you are in), I would estimate that over half of the trails are open to ORVs. Typically the northern trails are open to ORV, while the ones to the south are muscle powered only, via foot, bike or horse. The good news is that Capitol Forest is a big place and there is more than enough room for everyone, although it might be a little noisy on the weekends.
We started our hike from the Fall Creek Trailhead and hiked the Wedekind, Crestline, Greenline loop going clockwise.
In summary: The Capitol Forest is a lot of fun. Would I go here in the summer to hike when the high mountain trails open up? Probably not. But I do think it would be fun to come here in the winter months to keep conditioned since lots of low elevation (snow free) miles can be done here. If I lived near Olympia I would be coming here a lot. Mountain biking this would be a blast.
Driving Directions to Fall Creek Trailhead: Southbound & Northbound on I-5 take exit 95 (Maytown), go WEST towards the Farmboy Restaurant. Follow Maytown Road to stop sign by the Littlerock School. Proceed STRAIGHT (128th) going past the gas station and the tavern and head up the hill. At the stop sign turn RIGHT and follow Waddell Creek Road SW. Turn LEFT on Sherman Valley Road and continue west. At intersection of Noschka Road go west on C-Line Road 3.3 miles. Turn left on C-6000 Road and go south 2.5 miles. Trailhead is on right. (Disclaimer; I admit that I wasn't paying attention to how we got to the trailhead. These directions are cobbled together from a couple different sources I found on the internet. Use at your discretion. Another good reason to buy Craig's book when it comes out.)
