Oregon Hikers

Hello, we are hoping to backpack parts of the North Umpqua Trail but locating backcountry camping sites has been difficult! We r looking at the lower sections, dread & terror section and west to the beginning.

Had anyone been through and found great backcountry sites that will hold two tents worth with a water source?

Any advice is appreciated! I want to write a hiking book but always describe the camping site options!(highly missing in almost all hiking books, reports)
