The almost 900-acre Big Sky Nature Reserve is divided into two sections, the Valley of Eden Bird Sanctuary and the Home Farm Section. There are over 15 miles of trails to explore at Big Sky, which is managed and protected primarily for the many bird species that call it home.
In fact, the habitat here is so critical to many grassland species that the Valley of Eden Section was designated an ‘Important Bird Area” by Birdlife International/The National Audubon Society in 2020. To date, there have been documented sightings of over 120 different bird species at Big Sky with April through August being the prime viewing season. Notable Illinois species of conservation concern include the Henslow’s sparrow, bobolink, red-headed woodpecker, and northern harrier. More common species, such as a variety of other woodpeckers and neo-tropical migrants, can be seen here too, making Big Sky Nature Reserve a birding paradise for people of all ages and abilities. Please, NO dogs from March 1 to September 30th, annually, to avoid bird nesting season.
Trail access to horseback riders will resume during summer 2025.
