Cheyenne Mountain has three distinct peaks. At 9,570 feet, the highest point is within Pike National Forest and is where this cache is located. The other two peaks are the Antenna Farm and The Horns, both on private property.
Approach from the west to remain on public lands. Above all else, do not trespass on US Government property (NORAD). But also do not attempt to hike up the old road from the Will Rogers Shrine to The Horns (now The Broadmoor's Cloud Camp), or park along Old Stage at any point north of the National Forest boundary - about 4 miles from the bottom. Cheyenne Mountain State Park has built a new trail on land they recently acquired, and the Dixon Trail is another, but much longer, legal approach.
Suggested parking is on Old Stage Road (FR368) 5.7 miles from the bottom. The easiest hike is a somewhat circuitous 7.5 miles round trip with about 1000 feet of elevation gain. From parking, begin on the MacNeill Trail (also called Pipeline Trail), turn right at 2.2 miles onto the Swisher Trail, gain the summit ridge, then go off trail and follow the wooded ridgeline toward the southwest about 3/4 mile to the summit. It is also possible to reach the summit using a direct ascent of the Southwest Slopes (see waypoints and map for a suggested route).
You will be looking for an ammo can under some rocks. The summit log in a glass jar is not the cache.
Thanks to Spivey, original owner of this ammo can, and estes01 who rescued it from the Waldo Canyon fire zone.
