Calvert Cliffs State Park is a day-use park featuring a sandy beach, unique fossils, recycled tire playground, a freshwater and tidal marshland and 13 miles of hiking trails located in Calvert County. The massive cliffs from which Calvert Cliffs SP was named dominates the shoreline of the Chesapeake Bay for thirty miles in Calvert County and were formed over 15 million years ago when all of Southern Maryland was covered by a warm, shallow sea. When the sea receded 20-25 million years ago, marking the end of the Miocene period, 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.

Easy trail not moderate. Beautiful though and easy to follow. Went with two kids and it was easy and nice day together.

Not moderate. This is an *easy* trail. Great trail, beautiful change in forest type and ecosystems. Wish the cliffs were still available to explore. Great escape from DC.

$5 fee is the only reason I don't come more often. The trail is great for dogs and the beach is small but a nice place to relax. The trail has benches and mile markers.

Heavily trafficked, but kids had fun searching for fossils. We walked the Red Trail to the beach and used the service road to return. It was too long of a walk for a 3 and 1 year old, so we used a double stroller. The double stroller consumed most of the width of the Red Trail, and the stroller struggled on the roots on the red trail. We chose the service road for the return, and the person pushing the double stroller struggled with the hills on the service road.

Very nice and well maintained
