Rocky Mountain National Park

People have been rock climbing in the Rocky Mountains for more than 200 years, and for good reason. Rocky Mountain National Park is filled with granite rock formations for nearly every mountain scaling opportunity, including big wall, snow and ice, bouldering and all-out mountaineering. Climbers can tackle a quick boulder or spend days on the big walls. A must-see is Longs Peak, the 14,259 foot high summit that offers a climb on the Keyhole Route that must be taken with extreme caution — but that yields great rewards.
