Lake Granby offers multiple boat ramps for accessing this 7,256-acre reservoir: Stillwater Boating Site (two-lane ramp with courtesy dock, restroom, and gin pole on the western shore) and Sunset Point Boating Site (single-lane ramp with similar amenities on the southwestern shore).

All motorized boats require a Colorado Aquatic Nuisance Species inspection and can only launch when CPW inspectors are present; non-motorized watercraft like kayaks and paddleboards can launch at Roaring Fork without inspection.

An Arapaho National Recreation Area day-use pass is required for vehicle parking at all access points.
