One of the best places to camp in all of Colorado is the Boulderfield at Longs Peak, a waypoint on the most commonly traveled route to the iconic mountain’s 14,259-foot summit. A vast sweep of rocks located at 12,760 feet, the Boulderfield in Rocky Mountain National Park offers stunning views of a sheer, 900-foot wall on the mountain’s east face called the Diamond. A short hike away is the famous Keyhole, a gap in a massive ridge hikers use to reach the last 1,000 vertical feet of the climb to Longs’ summit.
