2010 Open Houses at Plum Island Light, Newburyport, Mass.

This year's open houses at Plum Island Lighthouse, an 1898 wooden lighthouse at the northern tip of Plum Island in Newburyport, Massachusetts, will be on these dates:

July 25, Aug. 29, Sept. 26 and Oct. 10

There is a short ladder to climb to the top, so sneakers are required. Children must be at least 5 years old and meet a height requirement to travel to the top. Tours are free, but donations to support the Friends of Plum Island Light, a nonprofit organization dedicated to preserving and restoring the lighthouse, are appreciated.
