Chesapeake Bay Environmental Center is operated by the Wildfowl Trust of North America with the goal of training environmental stewards of the bay. To get to the park from most of the state you will need to cross the Bay Bridge and continue just past Kent Narrows to Grasonville, MD. The visitor center has a lot of programs available for all ages. This park is a good birding and hiking spot with views of marsh, coastal pine forest, and the bay. Additionally, the park offers kayaks for tours and rentals.
There is no entry fee to the park. For more information, check out the Chesapeake Bay Environmental Center website.
