The middle section of the Owyhee from Three Forks to the Rome put-in is a 39-mile challenge, featuring Class III, IV, V+ rapids with boulder gardens, heavy hydraulics and steep drops. This one is not for the faint of heart. The aptly named Half Mile rapid offers nonstop adrenaline, as does The Ledge and the oft-portaged Widowmaker.

Guides on the Owyhee know the ins and outs of this tumultuous river best: Why not have someone cook your meal on the white sandy beach while you take in the desert sunset?
