Rich glacial soils support a lush growth of native woods in this hidden treasure. Horseback riders, hikers, bikers and cross-country skiers enjoy several miles of trail through the forest along Brule Creek. The trees and plants attract a variety of birds sure to keep botanists and birdwatchers entertained for hours. Campers enjoy the quiet well-shaded campsites, and the horse camp is the perfect base for a weekend of riding.
Deer, wild turkeys, beaver and many small animals abound in the park as well as a variety of trees and plant life. Birdwatchers will enjoy the opportunities to see many species of birds including cardinals, orioles, goesbeaks, warblers, red-winged blackbirds, bluejays, pheasants and wild turkeys.
The park is ablaze with color during the fall. Leaves changing color and the variety of birds attracted to ripening fruit trees create a spectacular autumn festival. Many area residents plan a fall trip to Union Grove to see the colorful show.
