Rugged Monhegan, aka the Artists’ Island, lies about a dozen miles out to sea, and is reachable only by passenger ferries. About 60 hardy souls live here year-round, most making a living from the sea. If you get a sense of déjà vu when visiting Monhegan, it’s likely because so many of the island’s icons and vistas have been painted by American masters, including Robert Henri, Rockwell Kent, Jamie Wyeth, George Bellows, Edward Hopper, James Fitzgerald, Andrew Wyeth, Alice Kent Stoddard, Reuben Tam, and William Kienbusch. Artists and art lovers come in summer; bird-watchers flock here in spring and fall. Hiking trails access remote rocky beaches and craggy headlands. Go for the experience, the art, and the hiking, and don’t miss the museum at the lighthouse.
