Welcome to Natural Lands Trust's Glades Wildlife Refuge, a 7,500-acre expanse of tidal marshes, wooded uplands, beaches along the Delaware Bay, and a remarkable old growth forest. While walking the Glades, you will want to keep your eyes on the skies as much as your GPSr. The tidal marshes are excellent places to spot bald eagles, as well as waterfowl and wading birds at any time of year.
