Parking is available at designated pull-offs along the highway. No public transport services directly access the canyon viewpoints.

Historical & Ecological Origin

Snake River Canyon was formed by the erosive action of the Snake River over millions of years. The underlying geology consists of Miocene-era basalt flows, part of the Columbia River Basalt Group. This region is classified as a high desert ecosystem.

Key Highlights & Activities

Observation of the canyon's geological formations is the primary activity. The canyon is also a site for BASE jumping, with specific regulations in place. Hiking is possible on informal trails along the rim, but caution is advised due to steep drop-offs.

Infrastructure & Amenities

Designated viewpoints offer basic signage. Restrooms are not available at the canyon itself; facilities are located in Ontario. Shade is minimal. Cell phone signal is intermittent within the canyon.

Best Time to Visit

Facts & Legends

The canyon is known for its association with Evel Knievel's 1974 attempt to jump the Snake River Canyon, which was ultimately unsuccessful due to technical issues with his rocket-powered cycle.
