Assateague Island National Seashore protects sandy beaches, salt marshes, maritime forests and coastal bays along a strip of barrier island that stretches across the Maryland and Virginia border. In this dynamic coastal environment, the island is continuously being reshaped by wind and water. Explore life on the edge of the sea by crabbing, clamming, kayaking, biking and camping – be sure to plan ahead, as campsites for the summer start filling up in March!

It was a serene moment; the air was calm and not a soul there disturbed the peace.” Photo courtesy of Dennis Liew.
