Leader: Stephanie Mason While most visit Calvert Cliffs State Park for the marine fossils along its Chesapeake Bay Beach, this protected tract in southern Maryland offers rich and varied natural history as well. We'll hike out to the Bay and back (a circuit of 4 miles) as we explore coastal plain forests, marshland, and stream valley habitats. We'll keep our eyes and ears open for all manner of fall wildlife activity, as we make stops along the way to enjoy plant communities in their seasonal aspects. The site's natural surface trails will be uneven and possibly muddy with a mild hill or two. The Park charges a $5 per car admission fee for MD tags and $7 for out-of-state tags. Carpooling will be encouraged and facilitated with a central meeting point not far outside the Beltway.
