The Post Canyon Recreation Area is a multi-use trail network formed of Hood River County property and a patchwork of State Park, USDA Forest Service, and private land. The area is also an ongoing tree farm operation, so be aware of potential closures. Expect traffic in both directions and yield appropriately.
A short downhill-only trail that was designed with mountain bikes in mind. There is a lot of high speed traffic and jumps along this trail. Runners may want to find another option.
