About Boulder Falls
Boulder Falls plunges about 70 feet in a compact, dramatic cascade tucked into Boulder Canyon. Framed by steep canyon walls, the falls are a very accessible and scenic stop for hikers and sightseers who want a quick taste of Colorado canyon scenery without a long trek.

The setting feels intimate—powerful water set against narrow canyon rock—and the short approach delivers big visual payoff for minimal effort.
