Summit three Acadia peaks on an 8.8-mile loop, passing overlooks of neighboring bays and island clusters along Maine's coastline.

From the Sieur de Monts Spring Nature Center, head southwest on the trail that switchbacks up the lower slopes of Dorr Mountain past intermittent views of the Porcupine Islands and Frenchman Bay. Midway up the mountain, the trail traverses south before cresting Dorr’s summit, dropping down a gully on the west face, and then climbing up the east ridge of 1,530-foot Cadillac Mountain—Acadia’s highest peak. At the top, expansive views of the Atlantic stretch out to the south, and options for lengthening or shortening this trip are available. This loop descends to Bubble Pond before climbing back up to the broad, 1,248-foot summit of Pemetic Mountain. After descending this third peak, the trail climbs to the top of one more ridge before descending along Canon Brook and heading north past The Tarn Lake back to the Nature Center.
