Walker ORV Main Staging AreaWalker Valley is located in North West Washington State about 70 miles north of Seattle, offering a DNR sanctioned light duty wheeling environment. There is a single primary loop for 4x4 enthusiasts that offers a solid day of wheeling. A majority of the park is dedicated for Motorcycle and Quad trails. The park is maintained and updated by a DNR crew and local ORV clubs.
The 4x4 trail trail system is designed for a stock Jeep with 31" tires to be able to make it through but a few obstacles may require a quick pull to climb over with a lightly equipped rig. A new challenge course has been added in the east corner of the trail system to give those with hard core wheelers a set of challenges other then the Expressway. Walker is well known for causing body damage to those who don't pay attention and can become a very different place after rain has changed most of the dirt trails to slick surfaces. On a wet day it is not recommended you run Walker Valley if you want to keep your body straight.
Expect to spend anywhere from 3-8 hours running the full loop with connections to the main road system available to allow for quick exists and helping injured vehicles out of the park.
