The Washington Backcountry Discovery Route is a 600-mile (970 km), mostly off-road trail traversing the Cascade Mountains in the U.S. state of Washington.
[1] The entire route is double track suitable for motorized users (four-wheel drive automobile or dual-sport motorcycle) and non-motorized users (mountain bike).
[1][2][3] The route was created by Bryce Stevens and Andrew Cull.
[1] In 2007 Steve Bisig of Pacific Northwest Adventures successfully completed and published a 4x4 route from the Oregon to Canadian border that consisted of more off-road trails (Washington Cascades Overland Tour).
[4] The state of Oregon has a collection of five interconnected routes that are similar to the Washington Route and was created in the late 1990s by the Oregon Off Highway Vehicle Association.
