John Wayne Pioneer/Iron Horse Trail
The John Wayne Pioneer Trail is what remains of an old railway that connected Milwaukie, WI and Washington state. It connects with the Iron Horse State Trail and can be ridden from the Cascade Range all the way to the Idaho-Washington border. It's a mostly flat ride but, do keep in mind, as you approach the eastern half of Washington, the soil is really sandy and loose.
Camping is a legal gray area - embrace the stealth within.
