​​​​​Boyd Lake State Park is a water-sports haven for northern Colorado. The lake lies at the western-most edge of the plains at the foot of snow-capped Long's Peak and the mountains of the Continental Divide.

Boyd Lake State Park has something for everyone: boating, fishing, camping, picnicking, swimming, hiking, biking, and hunting.

All types of watercraft: ski boats, fishing boats, jet skis, sailboats, canoes, use Boyd Lake's 1,700 surface-acres of water. Boyd also has a sandy beach and a pavilion for swimmers. Boyd Lake State Park also has a modern campground with 148 paved pull-through sites that can accommodate vehicles up to 40 feet in length. View an aerial view of the Cottonwood Campground.
