Cadillac Mountain is the tallest mountain on the eastern seaboard of the United States. The true summit is to the left where the South Ridge Trail opens onto the gravel access road. Look for 2 survey benchmarks established by the US Coast and Geodetic Survey in 1856 and the 1954. The South Ridge Trail is a gradual climb, but it has the advantage of not coming close to the Cadillac Summit Road until the end. The trail briefly descends to a small pond called The Featherbed, where there is a wooden bench for taking a break and enjoying the pond.
