Swimming is permitted at Calvert Cliffs Beach, but conditions require caution. The Chesapeake Bay waters here are generally calm, though jellyfish can be present in summer months. There are no lifeguards on duty, so swim at your own risk. The beach is rocky rather than sandy, so water shoes are recommended. Be aware of the cliffs themselves—while scenic, they're actively eroding. Never climb the cliffs or sit directly beneath them, as falling debris poses a serious hazard. Check weather and water conditions before your visit.

Spring and fall offer the most comfortable conditions for hiking and fossil hunting at Calvert Cliffs, with mild temperatures and fewer crowds. Summer (June-August) is popular for swimming but can be hot and humid, with more visitors. Winter visits are possible year-round, though trails may be muddy. For fossil hunting—the main attraction—visit after storms or during low tide when erosion exposes new specimens. Weekdays are generally less crowded than weekends. The park opens daily from sunrise to sunset throughout the year.

Calvert Cliffs State Park is located in Lusby, Maryland, about 60 miles southeast of Washington D.C. From Route 4, take Route 2/4 south, then follow signs to the park entrance. A main parking lot accommodates visitors, but it fills quickly on summer weekends—arrive early. Note that the beach requires a 1.8-mile hike each way on the Red Trail through forest, so plan accordingly. There's no vehicle access directly to the beach. Out-of-state vehicles pay a small service fee. Public transportation options are extremely limited in this rural area.

Calvert Cliffs State Park has minimal amenities—restrooms and a recycling center at the trailhead, but no food service. Pack your own water and snacks, as the round-trip hike totals 3.6 miles. The nearest restaurants and convenience stores are in Lusby, about 10-15 minutes away. For lodging, Prince Frederick (20 minutes north) and Solomons Island (20 minutes south) offer hotels and vacation rentals. The nearby town of Chesapeake Beach has additional dining options. Consider bringing a cooler for your vehicle, as there are no facilities at the beach itself.

Yes, Calvert Cliffs is genuinely famous for Miocene-era fossils, particularly shark teeth dating back 10-20 million years. The eroding cliffs continuously expose new fossils on the beach, making finds common for patient searchers. Look along the shoreline, especially after storms or at low tide. You'll find teeth from extinct sharks, along with shells, whale bones, and rays' teeth. Collecting is permitted for personal use only. Bring a small mesh bag or container. Remember: never dig into or climb the cliffs themselves—collect only from the beach. It's a legitimate fossil-hunting destination.
