Imagine the exhilaration of climbing a granite wall with the thundering waves of the Atlantic Ocean breaking against the rocks below. Or, perhaps you'd rather scale a difficult crag tucked within a quiet Maine forest. Whatever your style, Maine offers more than 400 rock climbing routes throughout the state. Maine also hosts climbing schools and rock gyms to hone your skills. Some of the places for you to consider include Mount Katahdin, Shagg Crag, and Acadia National Park. For information on routes, conditions, and degree of difficulty, check the Mountain Project website.
