Thing to Do

Hike Cadillac South Ridge Trail

Visitor hikes down granite trail marked with cairns

This out and back trail is the longer, more scenic option for reaching the summit of Cadillac Mountain. Ascend a forested path to a unique meadow-like area before continuing your climb on an exposed granite ridgeline with spectacular views of the Atlantic Ocean and outlying islands before reaching the summit. It is very popular in the summer months, with options to descend other trails and use the Island Explorer to return to the trailhead.

  • Distance: 7.1 miles roundtrip
  • Terrain and Safety: Forested path, granite ridgeline, one iron rung. The trail is rocky with uneven footing. Good foot wear is recommended.

Hike Description

  • The trail starts in a forested area and gradually steepens as it approaches the ridge.

  • At the junction with Eagle’s Crag, there is a .3 mi spur trail (Eagle’s Crag Loop Trail) to the right, which rejoins the South Ridge Trail. Take this for views from an overlook of the forest below and ocean further out.

  • Continue on the South Ridge Trail through the forest and reach The Featherbed, a small pond with a bench.

  • The trail climbs a steep section and becomes more exposed, eventually going above the treeline along the ridge.

  • It descends again, crossing an old road, and then ascends to the summit. Use the gravel access road to reach the summit parking area.

  • Return the same way, or choose Cadillac North Ridge Trail or Gorge Path for a shorter return and use Island Explorer to get back to the trailhead.

This trail is 7.1 miles roundtrip. Duration, or how long a hike takes, depends on your pace, how frequently you stop, and the terrain. For an average pace, this hike takes 2-4 hours. 
Dogs must be on a leash no longer than 6 feet. Note: There is one iron rung.
Although this activity is free, a park entrance pass is required for all areas of the park from May 1 through October 31.

Trail Safety Tips

  • Check trail elevation profile or a topographic map before hiking.
  • Bring a map, water, snacks, compass, and extra layers for unpredictable changes in weather.
  • Reduce the chance of picking up ticks by staying in the center of the trail, and not stepping on soils and away from brush.
  • Always do a tick check after visiting the park.
  • Closed-toe, good traction shoes recommended because most trail surfaces are very unlevel.
