9. Cascade-Siskiyou

Considered an “ecological wonderland,” the Cascade-Siskiyou National Monument exists at the confluence of the Cascade, Siskiyou and Klamath mountains, home to many species of butterflies, wildflowers and wildlife. From its highest reaches, you can stare south to Mount Shasta, north to Mount McLoughlin and out to the reaches of southern Oregon.

8. Hells Canyon

The deepest river gorge in North America, Hells Canyon plunges more than 7,900 feet at its highest point – nearly 2,000 feet deeper than the Grand Canyon. Isolated in the northeast corner of Oregon, the canyon above the mighty Snake River is rugged and wild, the scourge of many parties of pioneers who perished trying to explore it.
