Tilden Nature Area is a 740-acre preserve located North of Tilden Regional Park with over 10 miles of hiking trails. Hikes range from the leisurely, self-guided Jewel Lake Nature Trail to a steep climbs up Wildcat Peak. A 750-foot boardwalk through the woods leads to Jewel Lake, a historic reservoir and waterworks, and a peaceful place to watch wildlife. The nature area is visited by thousands of locals and tourists each year.
The naturalist staff offers interpretive programs throughout the year. Naturalist-guided programs for school groups and other organized groups are available Tuesday through Friday by advance registration. Weekend programs provide opportunities to learn about natural and cultural history throughout the Park District's Northwest region.
The Little Farm was built in 1955 and features a variety of farm animals including cows, sheep, goats, rabbits, chickens and pigs. Several heritage breeds are preserved here, including Milking Shorthorn Cattle. Visitors are welcome to bring lettuce or celery (but nothing else) to feed the animals.
Two group campsites are located in Tilden Nature Area - New Woodland (capacity 50) and Wildcat View (capacity 75), both located about one-quarter mile from the end of Lone Oak Road off Central Park Drive. All reservations must be made at least 14 days in advance.
