The Dearborn boat ramp at Highway 287 is a well-designed put-in for paddling the scenic 16-mile Dearborn River section (Class II-III whitewater) down to the Missouri River near Craig.

The ramp provides access to a remote, roadless canyon area with three notable rapids, including an unnamed Class III boulder garden near the middle of the float, and camping is available at the Mid-Canyon take-out on the Missouri River.
