Gunnison National River

The Gunnison River is a tributary of the Colorado River, approximately 180 mi long,

The Gunnison River ranges in width from 100 to 1000 feet and 3 to 50 feet in depth. The river's powerful current and many rapids make upstream travel nearly impossible.

Navigation through the entire canyon is dangerous and for experienced boaters only.

It is navigable for small craft throughout its course and by larger boats below the Black Canyon. Parts of the Black Canyon are unnavigable to any sorts of craft because of giant cataracts.
