Lighthouse Challenge

September 2021 (takes place every other year)
Lighthouse lovers are invited to take the challenge and visit ten lighthouses in two days during the Maryland Lighthouse Challenge from 8 a.m. – 6 p.m. Visit the Chesapeake Chapter United States Lighthouse Society web page for directions and complete details.

Visit Maryland’s historic lighthouses at some of the most beautiful spots in the state and see Concord Point, Seven Foot Knoll, Lightship Chesapeake, Hooper Strait, Choptank River Replica, Drum Point, Cove Point, Piney Point, Point Lookout and Fort Washington Lighthouses. Challengers receive a complimentary souvenir at each location. Visit all ten lighthouses and proclaim “you’ve seen the lights!” and receive a “special” souvenir.

To access Cove Point, we request visitors take a shuttle bus from CMM’s main campus to Cove Point to reduce traffic in the Cove Point community. Buses will start at 8 a.m. with the last bus leaving CMM at 5:15 p.m. and returning to the museum at 6 p.m.
ON SATURDAY ONLY, the Drum Point Lighthouse will be open from 8 a.m. to 5 p.m. The museum and Museum Store will close at 5 p.m. After 5 p.m., guests can view the lighthouse and take pictures from the area next to the Patuxent Small Craft Center. A table for challenge participants will be set up on the outdoor PNC Waterside Pavilion stage.
