Cadillac Mountain Summit Shuttle

The Cadillac Mountain Summit Shuttle is a convenient transportation option for visitors to Acadia National Park who want to reach the highest peak on the U.S. Atlantic coast without the hassle of driving and parking. Operated by the park's Island Explorer bus system, this shuttle runs during the peak summer and fall seasons, typically from late June through mid-October. The journey from the park's visitor center or designated stops winds through lush forests and granite slopes, culminating at the summit where you can take in sweeping views of Frenchman Bay, the Porcupine Islands, and beyond. The shuttle is especially popular for sunrise trips, as Cadillac Mountain is one of the first places in the United States to see the sun rise. The experience is not just about the destination; the ride itself offers glimpses of the park's diverse ecosystems, from spruce-fir forests to alpine-like rocky outcrops. Once at the top, you can explore short walking paths, enjoy a picnic, or simply soak in the 360-degree panorama. The shuttle helps reduce traffic congestion and environmental impact, making it a sustainable choice for exploring this iconic landmark.

A bit of history

Cadillac Mountain, named after the French explorer Antoine de la Mothe Cadillac, was originally called 'Green Mountain' by early settlers. The summit shuttle service was introduced as part of Acadia National Park's Island Explorer system, which began in 1999 to provide eco-friendly transportation and alleviate parking shortages. The service has since become a popular way to experience the mountain's sunrise and scenic views.
