Discover a world of natural wonder and outdoor adventure this summer at national wildlife refuges. Thrills await, whether you visit a refuge to see wildlife, enjoy a hike or a tranquil paddle, or catch a bass or a bluegill. Wildlife refuges can help you get fit while you’re seeing wildlife up close. In 2010 more than 40 million people visited a national wildlife refuge, generating about $4.2 billion in economic activity, according to an October 2011 report commissioned by the National Fish and Wildlife Foundation, a nonprofit conservation organization.
