Portland Head Light at Fort Williams State Park in Cape Elizabeth, Maine, is one of my favorite places to hike around with a camera. You've got a fantastic state park with old war ruins, hills and valleys and more, and then just turn east and you've got the ocean and the coast. Pretty good stuff.

Ram Island Light in Boothbay Harbor, Maine.
According to our friends over at Lighthouse Friends, "The walkway connecting the light tower to the island was so badly deteriorated that it was removed in 1977. Grand Banks Schooner Museum Trust, who has a lease on the station, has restored the keeper's dwelling and rebuilt the walkway in 2002."
