March 29, 2020.
Since mid-March, 2020, parks and preserves of all kinds, from national parks to local parks, have closed their grounds because of the Coronavirus pandemic. The list of closures across Maryland and DC has grown daily. In keeping with emergency laws restricting gatherings, essentially all facilities and organizations have cancelled group activities such as bird walks, programs, events, and festivals and have closed nature centers, visitor centers, and pavilions. Before you visit, call or check the website for any place you plan to go to find out if the grounds are still open.
