Thunder Lake Wildlife Area is an ecotourism hotspot in the Wisconsin Northwoods. This 3,000-acre wetland wildlife area is a great place to watch birds and view woodland wildlife. Spot owls, loons, cranes, osprey, warblers and sparrows as well as a variety of waterfowl and bald eagle. View white-tailed deer. Enjoy birding from the observation field. Watch birds and wildlife from the trail. And if you're visiting Thunder Lake in mid-summer don't forget to bring an empty container. Blueberry picking is a great way to make your family outing fun.
