The Friends of Portsmouth Harbor Lighthouses host open houses every Sunday from late May until mid-October. Climb the 44 stairs & 7-rung lantern up to the lantern room where you can enjoy the magnificent ocean views that include Whaleback Lighthouse and Wood Island Life-Saving Station at the entrance to the Piscataqua River.
Visitors also obtain elevated views of Fort Constitution, which is situated adjacent to the lighthouse, as well as the opportunity to admire the light’s working fourth-order Fresnel lens up close. Volunteers will share with you the history of the light station and answer your questions about this one one-a-kind maritime complex that is uniquely nestled between the shorelines of New Castle, NH and Kittery, ME.

Sundays: 1 p.m. to 5 p.m.
