About

Not far from Bar Harbor is a place to witness the sun's first rays in the United States. Welcome to Cadillac Mountain, the highest point along the North Atlantic seaboard! This magnificent granite landmark was created by tectonic and volcanic forces and glaciers that carved deep valleys, leaving the smooth bedrock visible today.

The first known inhabitants of the area were the Wabanaki people, who called the area Pemetic, meaning "sloping land." Here, they hunted, fished, and gathered resources along Maine's rugged coast and mountains.

In 1604, French explorer Samuel de Champlain sailed past the island. When spotting its granite summit, he named it Isles des Monts Déserts, or the island of barren mountains. Its current name honors Antoine Laumet de La Mothe, sieur de Cadillac, a French explorer and adventurer who died in 1918.

Conservationists George B. Dorr and Charles W. Eliot saw the need to protect the landscape from overdevelopment and acquired parcels of land. Later donated to the federal government, their effort led to the creation of Lafayette National Park in 1919, which became Acadia National Park.

While there are trails to the peak, the Cadillac Summit Road opened in 1931, replacing the cog railway that operated in the late 1800s. Today's paved tarmac not only provides an easier way to the top but also offers panoramic views of the forest, islands, and ocean.

Exploring the trails at the summit reveals unique geological formations and breathtaking vistas. The history and natural beauty combine to make this destination a cornerstone of any trip to the region.

Cadillac Mountain: Fun Facts & Cool Features

By far the most popular reason to visit is for the sunrises. From mid-May to early October, the summit lets you be the first people in the United States to see the sun's rays. Prepare to arrive pre-dawn and brave frigid temperatures and biting winds.

If you plan to drive to the summit, you'll need to obtain vehicle registration in advance. The 3.5-mile road winds up the mountain and is popular with cyclists and sightseers, so plan on driving slowly. Also, vehicles over 21 feet in length are not permitted on the road.

Speaking of cycling, if you're up for a challenging ride, check out the 4.7-mile Cadillac Summit Road route. While elevation is gradual, be prepared for spots where the gradient hits 10-12%. Best of all, you don't need to get a vehicle registration, but you are sharing the road with cars, so ride with caution.

If you're in shape, consider one of the various trails to the summit. The South Ridge Trail is a 7-mile trek that climbs 1,581 feet and is ranked "moderate" by AllTrails. You'll descend to The Featherbed, a small pond with a wooden bench for resting and enjoying the view.

A shorter hike to consider is the Cadillac North Ridge Trail. The 4.3-mile path climbs 1,151 feet, is "moderate," and features steep rock sections.

An easy, family-friendly hike is the Cadillac Summit Loop. The trail is a .4-mile loop that is flat (only 62 feet of elevation) and offers picturesque views and the chance to spot the 1856 brass disk in the bedrock. The United States Coast and Geodetic Survey set the marker to map the coastline and establish accurate elevations.

Another opportune time to visit is at sunset, offering a less crowded mountain-top experience. Additionally, if you bring warm jackets and blankets, stick around for stargazing!

Visiting Cadillac Mountain on a Maine vacation is a must-do! With views of Frenchman Bay, the Porcupine Islands, and the vast Atlantic Ocean, along with its rewarding sunrises, it's a destination you won't forget!
