If you like to hike, then Clegg Botanical Gardens, located in Lafayette, Indiana, is a great place to visit. It's a quiet, restful park nestled in a ravine in the Wildcat Valley. The Wildcat Creek meanders through it.
There is a lot of native Indiana flora and fauna. Visitors will see pretty wildflower beds, labeled trees, and plenty of nature trails and bridges. The fall is an especially beautiful time to visit, when all of the leaves change color.
The gardens are open year round from dawn to dusk. Admission is free.
