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.

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

Different type of trail than we are used to walking on as a good portion of the trail is sandy. Would not recommend doing it after a day of rain. Would put the difficulty closer to an easy than a moderate, especially if you do the red trail which is mostly on a boardwalk. The orange trail was completely empty when we did it, but we passed a lot of beach goers once we were on the red trail. We arrived at the park around 8 am and there was no one working the park entrance which was being run on the honor system. We didn't have the proper change so we had to throw in $10 instead of $5.

Pretty mellow trail. went yesterday 6/25/2017 and red trail was heavily trafficked with lots of people heading to and from the beach. Took the orange and blue trail and saw 3-4 people at most. VERY beautiful hike!

i ended up walking past the "entry prohibited" sign just before the cliffs, and wasn't chastised by park personnel.

i should've been bum rushed.
