Cadillac Mountain Visitors Guide – Acadia National Park

April 3, 2023by Thomas Tash

Cadillac Mountain, located in Acadia National Park in Maine, is the tallest mountain on the eastern seaboard of the United States. With an elevation of 1,530 feet (466 meters), it offers breathtaking views of the surrounding area, including Bar Harbor, Frenchman Bay, and the Porcupine Islands. Cadillac Mountain is a popular destination for visitors to Acadia National Park, and it is easy to see why.

Quick History of Cadillac Mountain

The mountain was named after the French explorer Antoine de la Mothe Cadillac, who established Detroit and was governor of Louisiana. The Wabanaki people, who lived in the area for thousands of years before European contact, called the mountain “Kadakit” or “Kadakodak,” which means “the highest point.”

Acadia National Park, of which Cadillac Mountain is a part, was established in 1916 as the first national park east of the Mississippi River. The park covers over 49,000 acres (198 square kilometers) and includes several other notable landmarks, including the Bass Harbor Head Lighthouse, the Jordan Pond House, and the Precipice Trail.

How to see the Sunrise on Cadillac Mountain in Acadia National Park

Cadillac Mountain is unique in that it is one of the first places in the United States to see the sunrise each day. From early October through early March, the sunrise from the summit of Cadillac Mountain is the first place to be seen in the United States. This phenomenon is due to the mountain’s location on the eastern seaboard and the curvature of the earth.

To witness the sunrise from Cadillac Mountain, visitors must wake up early and make their way to the summit before dawn. The exact time of the sunrise varies depending on the time of year, but typically ranges from 4:30 am to 6:00 am. Click here to view the sunrise time at Cadillac Mountain. It is important to check the local weather forecast before planning a sunrise viewing, as cloudy or overcast skies can obscure the sunrise and diminish the experience.
