The following parks are among Maryland's most popular and serve a very high volume of visitors during summer weekends and holidays.

Assateague State Park

Cunningham Falls State Park

Greenbrier State Park

Point Lookout State Park

Rocky Gap State Park

Sandy Point State Park

Seneca Creek State Park​

To ensure the safety of our visitors and protection of the park’s natural resources and facilities, these parks have a limited capacity.

During periods of high visitation, when the park’s capacity is reached, these parks 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, these parks 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.
