Chesapeake Bay Beaches and Calvert Cliffs
For 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.

Hiking and Exploration
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, a fishing pier 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.
