Large and central to Loveland, Boyd Lake State Park offers visitors the opportunity to walk, relax, and boat around the cool waters of a lake. Much larger than neighboring Loveland Lake, the friendly confines of Boyd Lake State Park offer an extensive list of amenities and activities. Topping this list, of course, is the lake expanse, spanning 1,700 surface acres and reaching depths of 50 feet. The lake allows all types of watercraft access, available at a boat ramp and marina, although non-motorized boats may find it more convenient to launch from one of Boyd Lake’s banks. The day use area at Boyd Lake State Park offers concessions, a large playground and swim beach, covered picnic shelters, and a fishing pier. A campground at Boyd Lake offers 148 campsites and convenient amenities that include showers and a laundry facility.
The trail network is level and makes for easy hiking. The trails begin in the northwestern corner of the lake, traversing the park area along the western rim of the lake, weaving through meadows thick with grass and along the banks of the lake. A Colorado Department of Transportation road, which circumnavigates the southern rim of Boyd Lake to Regency Park, may extend hikes by an additional mile or so. Many of the trails around Boyd Lake permit biking and cross-country skiing in addition to walking. In the winter, Boyd Lake becomes a beautiful setting for snowshoeing and cross-country skiing close to Loveland when the snows fall from November to May.
Boyd Lake is also the site of some historical buildings, part of a homestead constructed by Carl Heinricy in 1875. Heinricy's son, Henry, who purchased the homestead in 1887, was responsible for an irrigation project, the Eureka Ditch, in what became Rocky Mountain National Park. The Boyd Lake State Park visitor center rests on old Heinricy land, and a stone root cellar and pump house remain standing today.
Pets are allowed at Boyd Lake State Park, but they must be kept on a leash at all times.
