Hyland Park Reserve is run by the Three Rivers Park District, and it's 1,000 acres of pristine wetlands, marshes, and other flora. It has miles of hiking and walking trails, and a biking path as well. There is an open play area for children that has won awards for its design. This is just the tip of the iceberg of what it has to offer. It has disc golf, skiing (downhill, telemark, and cross-country), dog trails, canoeing, snowboarding, and more. It also hosts the Richardson Nature Center, which can teach you a lot about animals and nature. You could spend all day here and not experience all it has to offer.
