This is a strenuous hike and should not be taken lightly. The Saddleback Range offers no protection from lightning or severe rain or snow. Avoid this hike in inclement weather. From the trailhead on Maine 4, follow the AT north and cross Sandy River on a footbridge in .1 mile. From Sandy River, hike 1.3 miles to Piazza Rock Lean-to.
Water is available from the nearby stream.
A short side trail leads to Piazza Rock. After leaving the lean to, the AT leads .9 mile to Ethel Pond and another .5 mile to Eddy Pond, which sits at the base of the climb up Saddleback. The trail ascends steeply up the west side of the mountain, gaining well over 1,000 feet in elevation during the first mile. Just .25 mile from the summit of the Horn, the trail drops below beeline again, continuing to descend sharply off the Horn and reaching the short, steep climb up Saddleback Junior. Water is available from the nearby stream.
