About Calvert Cliffs State Park:

The massive cliffs, from which Calvert Cliffs State Park was named, dominate the shoreline of the Chesapeake Bay for roughly 24 miles in Calvert County and were formed over 10 to 20 million years ago when all of Southern Maryland was covered by a warm, shallow sea. When the sea receded the cliffs were exposed and began eroding. Today these cliffs reveal the remains of prehistoric species Including sharks, whales, rays, and seabirds that were the size of small airplanes.

The 1/4-mile sandy shoreline at Calvert Cliffs State Park is the main destination for most visitors. It requires a 1.8-mile walk from the parking lot to get there.

Fossil hunting can be done at the open beach area at the end of the red trail. Over 600 species of fossils from the Miocene era (10 to 20 million years ago) have been identified in the Calvert Cliffs. Chesapectens, Ecphora, Miocene era oyster shells, and sharks teeth are common finds.

The area beneath the cliffs is closed due to dangerous land slides and the potential for injury. It is illegal to collect fossils beneath the cliffs.

In addition to fossil hunting and swimming, there is a recycled tire playground; 13-miles of nature trails; camping; and fishing at Calvert Cliffs State Park.

NOTE: Calvert Cliffs State Park is a popular summer destination. Check the website for information about when and how the park closes due to full capacity.


Bring your own sieves and shovels to sift the sand for fossils. You get to keep what you find.
