Chesapeake Bay Beaches and Calvert Cliffs

Chesapeake Bay beach at Flag Ponds Nature ParkFor hundreds of years the forces of nature have reshaped the Chesapeake Bay shoreline of Flag Ponds Nature Park, creating a remarkable variety of natural environments--from sandy beach, to freshwater ponds, to the forested heights of Calvert Cliffs. Today, nature continues to play with the sand, changing the park’s landscape with each tide, each storm, each season.

Fossil Hunting and Beach Combing

Millions of years ago, sharks, whales, crocodiles and other creatures inhabited the waters and shores of this area. Most of these animals are now extinct, others are just no longer found here. To the sharp-eyed visitor, sharks teeth and other Miocene fossils may be found along the park’s shoreline.

A short, half-mile hike brings you to the sandy beach or you may take longer trail routes that allow you to experience the beauty of the park. Additionally there are observation platforms at two ponds and on the Chesapeake Bay and a visitor’s center with wildlife displays.

A Part of Maryland’s History

From the early 1900’s until 1955 the area was a sheltered harbor on the Chesapeake Bay supporting a major "pound net" fishery supplying croaker, trout and herring to markets as far away as Baltimore. At one time, three shanties housed fishermen during the main fishing season. Known as "Buoy Hotel", the last surviving shanty was destroyed by arson in October 2012. 

Public Deer Hunting will open in mid-December for bow-hunting only. Specific information about hunting at Flag Ponds Nature Park can be found on on the Calvert Parks website

To make a reservation contact the State Department of Natural Resources Southern Region Public Hunting Permit and Reservation System online or by phone at the Myrtle Grove office at 301-743-5161.
