Three Mile Lake Access provides a hard surface boat ramp and fishing jetty for launching watercraft on the 880-acre lake located 3 miles north of Afton.

The access point includes amenities such as parking, restrooms, picnic areas, and a fish cleaning station, making it a well-developed launch facility for both boaters and anglers.

Note that the lake level was lowered 11 feet as of September 2024 for fishery renovation, which may affect launch conditions.
