Anyone planning a visit soon to Acadia National Park in Maine will have to deal with a temporary closure affecting one of the park’s most famous attractions. Since November 9, 2026, Cadillac Summit Road has been closed, the scenic road that allows visitors to drive to the summit of Cadillac Mountain, best known for its spectacular views over the Atlantic Ocean and its sunrises.
The National Park Service has scheduled two closure periods, in November and December, to allow certain maintenance work to take place. The restrictions apply not only to cars, but also to cyclists and pedestrians.
Cadillac Summit Road: the closure dates
According to the official National Park Service notice, the road will be closed during the following periods:
- From November 9 to 25, 2026
- From December 1 to 18, 2026
Between November 25 and 30, a reopening window is planned, during which it will be possible to reach the summit by car, weather permitting.
However, the usual winter closure of the road to automobile traffic will also take effect starting December 1. As a result, the end of November could be the last chance in 2026 to reach Cadillac Mountain by car.
Dates may be subject to change in the event of snowfall or adverse weather conditions.
Why is the road closed?
The work involves creating an accessible pedestrian path between the eastern and western parking lots located at the summit of Cadillac Mountain.
The project aims to improve the area’s safety and accessibility, preventing visitors from having to walk along the road used by vehicles to travel between the two parking lots.
During the work, Cadillac Summit Road will be completely closed to traffic, including for anyone who wants to walk or bike along it.
The hiking trails leading to Cadillac Mountain will remain open instead, allowing hikers to reach the summit via the authorized routes, weather conditions permitting.
What changes for those visiting Acadia National Park?
Cadillac Mountain is one of the main attractions of Acadia National Park. At 466 meters high, it is the tallest mountain along the Atlantic coast of the northern United States and offers panoramic views of the islands and the Maine coastline.
The road closure does not mean the entire park is closed; it remains open to visitors even during the fall and winter months.
Keep in mind, however, that starting December 1, much of Park Loop Road will also be closed to vehicle traffic, the scenic road that passes through some of the most famous areas of Acadia.
During the winter, weather permitting, some sections will remain accessible, allowing access to Sand Beach via Schooner Head Road and to Jordan Pond via Jordan Pond Road from Seal Harbor.
Anyone planning a trip to Maine in the coming weeks should therefore check road conditions before setting out, especially in the event of snow or ice.
