In Gwynns Island on the Piankatank River at the northern edge of Mathews County, the Hole in the Wall is a Chesapeake Bay boating circuit legend: a small, genuine, community-waterfront grill with dock access, fresh local seafood, cold beer, and the kind of tucked-away, unpretentious Bay character that its name perfectly captures. Boaters seek it out specifically because it is not easy to find; the reward is a bar that justifies the navigation.
