Located on the doorstep of DownEast Acadia and right next door to Fort Knox, the Penobscot Narrows Bridge and Observatory offers visitors an extraordinary 360-degree panoramic view of the Penobscot River and Bay, and the surrounding Maine countryside and coastline.

The Penobscot Narrows Bridge is one of only four bridge observatories in the world. And at 420 feet in elevation - that’s 42 stories – it is the tallest occupied structure in Maine and the highest bridge observatory in the world. The bridge spans 2,120 feet from the east shore to the west shore and rises 135 feet above the Penobscot River.

Combined with exploring the adjacent fort, a stop in at the top of the bridge is the True Maine way to begin any visit to DownEast Acadia.
