Um. . . There are rock crawling areas in WA, sure, but not to the extent of other areas of the country. The trails are fun and entertaining with some great scenery but not "hardcore" such as you see in magazines and such. The eastern side of the mountains is drier with great vistas and scenery that open up on the trails and miles and miles of area to explore. The western side is wetter with dense, lush evergreen forests.
The key to Washington's wheel'n opportunities is "variety," you get a taste of everything here. The benefit is that there are plenty of areas to go wheel'n that are close to Seattle. The following are approximate drive times from downtown Seattle:
Within a 1 hr Drive:
Reiter Trails ORV area
A fun area in the foothills of the Cascade mountains. A few abondon mines dot the wooded area. There are some creek crossings, a tall 700 ft cliff overlook, lots of mud puddles, and some nasty, slick boulder gardens to play in. This place is frequented by custom rock buggies and such. Elevation is pretty low so the chance of snow is remote.
Walker Valley ORV Park
A little further up north near this is getting to be a fun area. No rock crawling but the trails are entertaining enough for medium-to-full day of wheel'n and it's definitely worth the trip at some point for a change of pace. Like most Western WA trails they get muddy and slick with a mix of logs, rocks, stumps, and puddles to driver over and through.
Evan's Creek ORV Park
Probably one of the most popular ORV parks in the area this is sited at about 4000 ft of elevation in the foot hills at the base of Mt. Rainier. In fact, you can look right at the side of the 14,400+ ft tall mountain from an overlook on a trail. Trail difficulty goes up in the rainy season (Spring or Fall) with slick mud on everything, it gets easier when its dry (summer) and is virtually shut down in winter under 3-5 ft of snow for all but the insane. Many steep, tight, twisty mountain trails. Dark, lush, desne NW forests cling to the sides of the mountains in the ORV park providing a nice place to Jeep.
