A large population of white-tailed deer call the park home, and wild turkeys roam freely through the cabin and tent camping areas. Beaver, muskrat and mink prowl the river banks, and the varied bird life ranges from the majestic eagle to the tiny chickadee. The song of the whippoorwill blends with the call of the coyote in a nighttime serenade. For the wildlife enthusiast, Niobrara offers ample photo opportunities or just the chance to observe the many species native to the area. Nature's bounty is readily visible during a drive along the park's seven miles of roads or a stroll along the 14 miles of hiking trails.

Niobrara State Park offers a modern swimming pool; horseback trail rides led by wranglers; fishing in the nearby rivers; hiking the 14 miles of trail; bird watching and other nature study, or just a chance to loll in the shade away from the hectic pace of day-to-day living. Saturday evenings, Memorial Day through Labor Day, Niobrara State Park hosts a Buffalo Cookout.
