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 to hikers and equestrian riders.
Hidden Trail is a short, aggressive descent over loose cascading drops stuffed with rocks. All the fun quickly culminates to a steep roll-down onto Road 1004 across from Basswood (130). The exit is blind and intersects with a road used by dirt bikes, so you'll want a spotter to go ahead if you plan to send it.
