The 5.3 miles climb up Saddleback Mountain starts northbound at the Appalachian Trail crossing on route 4 in Sandy River Plantation, Maine. The first 2 miles climbs gradually over moderately technical terrain, passing many large boulders and caves. Then the trail starts climbing steadily and steeply over rocks and boulders. Footing is very challenging. About a mile from the summit the trail rises above tree line and continues to climb over rugged alpine terrain. The panoramic views are well worth the effort.
This is an out and back route, so return to the parking area on route 4.
