Situated in Aurora about fifteen minutes south of the airport, this park is a giant hive of activity year round. In warm weather, the 880-acre reservoir opens to swimmers, boaters, jet-skiers, volleyball players, and fishermen; in wintertime, there’s cross-country skiing, ice skating, snowshoeing, and sledding. And that’s just the beginning: picnic areas and campgrounds mean that you can go biking, hiking, horseback riding, sharpshooting, birding, model airplane flying, and more for days on end. Gather all sorts of materials about local flora and fauna, equipment rental, and children’s programs at the park office.
