Chincoteague Bay is the largest body of water within Maryland's Coastal Bays system, covering approximately 72.6 square miles or 46,483 acres. This expansive, shallow bay is a polyhaline estuary, meaning it maintains a consistently high salinity level, which supports a robust inshore saltwater fishery. The bay's waters are bordered by both Worcester County, Maryland, and Accomack County, Virginia, offering extensive opportunities for recreational angling from both shore and boat. Its protected waters provide a haven from ocean swells, making it a popular destination for family fishing trips, crabbing, and targeting a variety of popular sportfish throughout the year.
