Lathrop State Park provides multiple access points to Horseshoe Lake Reservoir, including a boat ramp on the north side of the lake and an ADA-accessible canoe/kayak launch on the south side.

The no-wake lake accommodates non-motorized watercraft like kayaks and canoes, with parking available at designated areas on the northwest and southwest corners of Horseshoe Lake Road.

A visitor center near the park entrance sells passes, supplies, and provides information about current lake conditions.
