A fortunate few have visited Thacher Island and toured the fully restored north lighthouse. This Cape Ann set of twins has been designated as a National Historic Landmark and remain the only operating twin lighthouses. Those wanting to visit Thacher Island can take the island launch on Saturday mornings during July and August. The launch holds 15 passengers and takes the trip each Saturday. If you're doing the math, figuring the amount of visitors per summer, don't forget there is a factor of New England's inclement weather.
Thacher Island is just off the Massachusetts coast from the town of Rockport. The island's granite base supports the lighthouses, the keepers quarters, oil houses, a barn and graveyard. The Thacher Island twins are two of six lights found along the Cape Ann coastline.
