The only place I can think of is Evan's Creek. It is maybe a 35-40 min drive from Ft. Lewis.
I posted some directions to Evan's Creek and a suggested meeting point on my website. Here is the info:

Burnett is such a small town that its mailing address are lumped in with Buckley. As the town is only 3 blocks long the Chevron Station make an excellent meeting point since it is so visible. It is also a place to top off with gas, get any ORV day passes, or some munchies.
Getting TO Evan's Creek:
1. From the Burnet Chevron, continue out SR 165 and stay on the main route as it passes through Wilkeson. Eventually the road winds along the edge of a cliff before crossing a green steel bridge over a tall gorge.
2. Just past the bridge is a sign for Evan's Creek and the road comes to a 'Y'. Stay to the right. Evan's Creek is approximately 7 miles up the road. After a mile and a half it turns to gravel.
3. Continue on the road until you see a BIG sign that says Evan's Creek ORV Park. There is a sign board about 1/2 mile before the actual park entrance. . . this is the back entrance and not the main way in. Continue on.
You can get day or year passes at the Burnett store as well as fuel up there. Punch in the address for the store in google to see where it is. It's not technically in Buckley but Burnett is so small it's addresses are lumped in with the slightly larger town. It's maybe another 15-ish miles from Burnett to Evan's Creek.
Ok, HERE IS THE GOOGLE MAP
It shows how to get right to the Evan's Creek staging area. Point A is the Fort Lewis area, Point B is the Burnett store (gas station) and Point C is the staging area for Evan's Creek.
