The Mountains Are Calling
Trail Rating System: Acadia National Park rates each of its trails from E (easy; mostly level ground), M (moderate; gradual inclines with uneven footing), and S (strenuous; steep, rocky inclines), to L (look out! I mean, ladder; strenuous, with iron rungs or ladders added so you can cross narrow ledges or cliff faces).
A trail’s length, of course, is no indication of its difficulty. The 0.5-mile stroll across to Bar Island (E) is much different than the 0.6-mile Ladder Trail (L) up the east face of Dorr Mountain. And the 3.2-mile hike around Jordan Pond (M), one of the longest in the park, takes much less effort than the 3.5-mile climb up the South Ridge of Cadillac Mountain (S).
