A visit to the Stone Harbor Bird Sanctuary may not have the thrills of an amusement park or a summer sports outing, but, when nature calls, it’s best to answer. Ideal for a low-cost day out with the entire fam or alone time with a single member of your brood, this serene spot is free, open to the public and just a short drive from the Philadelphia area. Take a hike along the beach, pass by the saltwater streams, climb over the sand dunes and tiptoe through the old maritime forest. With wading birds, songbirds, wildflowers and butterflies to spot, the sanctuary is both a priceless educational opportunity and a peaceful family expedition! While you’re in the neighborhood, extend your environmentally-themed field trip with a stop at the nearby Wetland Institute. Spend the last few days of summer outdoors . . . school will be here in a heartbeat.
