Hikers enjoy the paved and gravel trails beside the beaches, and under the shade of cottonwood trees next to the water's edge. Boyd Lake's trail is a segment of the City of Loveland's recreation trail system.
From I-25, take exit 257 and travel West. Continue on Highway 34/East Eisenhower Boulevard to Madison Avenue (appx 3 miles). Turn North on Madison Avenue (right turn) until you reach East 37th Street (appx 1 mile) where you will go east (right turn again). Follow E. 37th Street for about 1/2 mile, it curves north and is renamed County Road 11-C, Boyd Lake State Park is on the East side of this road.
