The Maroon Bells are two peaks in the Elk Mountains, Maroon Peak and North Maroon Peak. Their peaks are 14,156 and 14,014 feet, and they are 1/3 mile apart and 12 miles southwest of Aspen. Both peaks have an elevation gain of 4,500-4,800 feet, and both are accessed by the Maroon Lake trailhead.
The different between Maroon Peak and North Maroon Peak is the difficulty of the climbs. Maroon Peak has a difficulty of Class 3 and a 4/6 exposure, meaning a pretty serious exposure that could result in serious injury if you fell,hiking past the area will require some scrambling or short technical moves.
North Maroon Peak has a difficulty of Class 4, rope is often used on Class 4 routes because falls can be fatal; the terrain is often steep and dangerous, although some routes can be done without rope because the terrain is stable. The exposure of this peak is the same as the Maroon Peak.
