Walk one trail in Calvert County and land on a beach full of ancient shark teeth

It’s a hike, a history lesson and a hunt

Calvert Cliffs State Park sits on the western shore of the Chesapeake Bay in Calvert County, Maryland, and it does something almost no other park can: it lets you walk a forest trail straight to a beach covered in prehistoric shark teeth.

The cliffs behind that beach formed between 10 and 20 million years ago. You can pick up what’s washing out of them with your bare hands.

That’s the part that stays with you long after the drive home.

When a warm sea covered all of Southern Maryland

Ten to 20 million years ago, a warm, shallow sea covered the land where Southern Maryland now sits. Sea creatures lived and died in that water, sank to the bottom, and slowly turned to fossils.

When the water pulled back, the cliffs were left standing.

Now they line about 24 miles of Chesapeake Bay shoreline, and every tide and storm chips away at the face, nudging more of that buried past down to the sand below. The cliffs keep eroding.

That’s the whole reason you can find anything at all.

Over 600 species of fossils locked inside the cliffs

Calvert Cliffs ranks among the richest fossil sites on the East Coast. Researchers have identified more than 600 species preserved in the layered rock.

Sharks, whales, rays, and large prehistoric seabirds all left their remains behind in those bands of sand and clay.

The cliffs work like an open-air geology textbook, with each layer representing thousands of years of buildup on an ancient sea floor. Every storm rewrites the page a little.

What comes tumbling down lands on the beach, waiting for you.

Shark teeth wash up right at your feet

Shark teeth are the most common find on the beach, and you can keep anything you spot on the open sand. Most are small, dark, and triangular, easy to miss if you’re walking fast.

Megalodon teeth do turn up, but don’t count on it. Rare finds happen, and that possibility is enough to keep people scanning for hours.

Along with the teeth, you might find fossilized shells, ray plates, and other fragments of ancient sea life. Low tide opens more beach and gives you the best window to search.

The 1.8-mile Red Trail keeps the crowds thin

The beach has no parking lot of its own. You get there by hiking the Red Trail, a 1.8-mile path from the main lot that winds through shaded deciduous forest on mostly flat ground.

The walk takes about 40 minutes at an easy pace. Young children handle it without much trouble.

That distance is also why the beach stays relatively quiet. Most people who want a quick dip don’t make the effort, which means more sand for the ones who do.

Pack water and snacks before you head out because there are no concessions anywhere in the park.

A boardwalk floats above the marsh

Partway along the Red Trail, the path lifts off the ground and crosses a boardwalk over open wetland. In summer, lily pads spread out in every direction and frogs call from the reeds.

The boards reach out over the water in spots, close enough that you’re standing above the marsh, not just walking beside it. A few benches sit along the railing if you want to stop and watch.

It’s one of those stretches where you forget you’re on the way to somewhere else.

Thirteen miles of trails through quiet forest

The Red Trail gets the most traffic because it leads to the beach, but the park has 13 miles of marked trails total.

Other routes wind through woods away from the main crowd, well-maintained and suited to a range of abilities.

On a hot summer day, the forest canopy keeps the temperature down and makes the whole place feel cooler than it actually is.

If you want to extend your visit beyond the beach, the trail network gives you plenty of room to wander without retracing your steps.

A small, calm bay beach that earns its quiet

The beach itself is a quarter-mile stretch of sand facing the Chesapeake Bay.

The water runs shallow and calm, and swimming is allowed, though there are no lifeguards on duty, so you swim at your own judgment.

The fossil-bearing cliffs rise nearby, but the area directly beneath them is closed because of dangerous landslides. Fossil hunting stays limited to the open beach at the end of the Red Trail.

Climbing on or walking under the cliffs is illegal, and the park takes that seriously.

Herons, ospreys and beavers share the park

The mix of forest, marsh, and shore draws a wide range of animals. Great blue herons and egrets work the edges of the wetlands, and ospreys circle overhead.

Turtles pull themselves onto logs to bask in the sun while frogs hop through the shallows. Beavers and muskrats stay active in the watery sections of the park.

Go deep enough into the forest and you start hearing wood thrushes and barred owls. The wildlife alone is worth the walk, even on days when the fossil hunting is slow.

Read millions of years of history in the cliff face

Stand at the base of the cliffs and look up at the exposed face.

You can see distinct bands of sand, clay, and shell stacked on top of one another, each layer representing thousands of years of ocean floor.

The whole thing reads like a record of deep time pressed into the earth and left open for anyone willing to walk out here and look. Every tide pulls a little more of it down.

What washes onto the beach today was sitting inside that wall for millions of years before this morning.

Kids can hunt fossils and burn energy at the playground

The flat trail and gentle bay water make this one of the more manageable outdoor outings for families.

Children can hunt the sand for their own shark teeth, which turns the whole beach into a treasure hunt with real payoffs.

Back near the park entrance, a playground built from recycled tires gives younger kids another place to run after the hike. The shallow water along the shore is calm enough for wading on warm days.

It’s the kind of trip where kids remember what they found, not just where they went.

Calvert Cliffs leaves a mark that lingers

There aren’t many places where you can pick up something 10 million years old and slip it into your pocket.

Calvert Cliffs lets you do exactly that, and the combination of deep forest, open marsh, bay water, and ancient geology makes it feel far removed from the suburbs and cities nearby. The park rewards a slow pace.

Go on a weekday if you can, or arrive early on weekends because the lot can fill to capacity by mid-morning. Give yourself most of a day and you’ll leave with more than you brought.
