Bill Frank Jr. Nisqually National Wildlife Refuge

Fodor's Choice

More than 250 different bird species along with a slew of reptiles, mammals, and amphibians thrive amid the marshes and grasslands of this 4,529-acre refuge—the largest estuary restoration in the Pacific Northwest—situated on the delta formed by the Nisqually River's confluence with Puget Sound. Just 8 miles east of downtown Olympia, the tranquil space feels a world away from civilization and is laced with 4 miles of trails, some of them along boardwalks. Naturalists lead guided walks and give lectures on weekends from April through September, and a visitor center contains exhibits and a nature store.
