Plan Ahead for "Filled To Capacity" Park Closures

Patapsco Valley State Park is one of Maryland’s most popular parks and serves a very high volume of visitors during summer weekends and holidays. To ensure the safety of our visitors and protection of the park’s natural resources and facilities, the park has a limited capacity.

During periods of high visitation, when the park’s capacity is reached, the park will be closed and traffic will be turned away from the park entrance. When that occurs, no additional vehicles / visitors will be allowed to enter the park, including those with members of their party who may already be in the park. If you are not traveling in the same vehicle with others in your party, we suggest that you all arrive at the same time.

When the park is closed due to being full to capacity, individuals and groups with shelter and/or camping reservations will be admitted, as parking is reserved for those purposes.

Based on recent experience and visitation trends, and depending on good weather, Patapsco Valley State Park will likely fill to capacity and close on Memorial Day, Fourth of July and Labor Day holiday weekends, and other weekends during the course of the summer. Please take this into consideration when planning your trip.
