Lighthouse Beach
Main Street at Bridge Street, Chatham, MA 02633
The dramatic, ever-shifting beach below Chatham Light, where breaks in the offshore barrier let the Atlantic roll right in. Stunning to walk and photograph, with seals usually visible offshore — but rip currents and sandbars make it a swim-at-your-own-risk beach.
