Oregon’s Klamath County boasts extraordinary diversity:  It straddles the Southern Cascades and a basin beyond the mountain range’s eastern face, making way for expansive farmland, old-growth forests of hemlock and Douglas fir, and Mars-like lava flows on the slops of Brown Mountain.  And while you can enjoy most of that natural beauty from behind a windshield, there’s no better way to experience that rich variety than from the seat of a bicycle along one of the region’s many accessible trails, or open roads.
