West of Somes Sounds is the quieter side of Mount Desert Island, here the major Acadia National Park Trails go up the mountains along the edge of the sound and Echo lake. To reach the trailhead for St. Sauveur Mountain travel south from Somesville on the ME 102 for 3.2 miles. There is a parking lot, on the (east) left side of the road with a brown park sign that says “ST. SAUVEUR MT. PARKING”. This is considered part of the national park so a parking permit is required for day use. They must be purchased from the Acadia park headquarters or a local retailer before parking; they cannot be obtained at trailheads. The cost is $20 per vehicle per week and are also required if camping or recreating within the boundaries of the national park. Dogs are also required to be leashed and cleaned up for at all times with a maximum 6 foot leash. There are no facilities at the trailhead for human use either, so keep this in mind.
The Ledge trail leaves the parking area and crosses a wooden bridge. It climbs gradually at first up some old boulder fields through an evergreen forest and then more moderately as it gains the ridge of St. Sauveur Mountain. The trail is blazed with deep blue and is easy to follow if you keep an eye out for the blazes on the more rocky sections of trail. The fire tower on Beech Mountain is visible before reaching the .6-mile junction with the Sauvuer trail.
The wooded summit of St. Sauveur is reached at .8 miles. Continue on the trail to Valley Peak for the views at 1.2 miles. From the summit of Valley Peak the Somes Sound and Cranberry Islands can be seen. It is a small summit and very easy to reach via the ledges trail. The dogs had no issues at all with climbing the trail, there was water along the way, but with a hike this short water and food were not a main concern. Turn around and retrace your steps along the St. Sauveur trail and take a left at the second junction with the Ledge Trail at 2.4 miles and at 2.6 return to the parking area.
