Castle Mountain from the summit
The views of toothy Castle Mountain from the summit of Oldman Mountain

Though petite, this rocky little wonder is an Estes Park area classic. A short but sweet scramble brings the hiker to a wide-open, rocky summit that affords dynamite views of Castle Mountain, Longs Peak, Mount Meeker, Twin Sisters, Lumpy Ridge and downtown Estes Park. The peak rises distinctly directly west of the town of Estes Park and is a distinctive landmark from several vantages points east. No marked trail reaches the top and some Class 3 scrambling is required to summit.

This rocky little perch is special for more than its fine views and pleasant scrambling:

Its history includes it as being one of the oldest and largest sacred Native American sites in Colorado for more than 5,000 years. Old Man Mountain is one of only three documented Colorado "vision-quest" sites; a pilgrimage site for Native Americans who would travel great distances and fast for several days upon the mountain peak as they awaited a divine message.

To this day, some people visit Oldman Mountain not for the rock scampering or the scenery but for spiritual reasons.

Old Man Mountain rises near the junction of US 34 and US 36 on the west end of Estes Park, Colorado. While trails run from the vicinity of Deer Mountain to the west, apparently the west face of Oldman Mountain promises a technical ascent. Most visitors to this peak will approach the mountain from the from UNC (University of Northern Colorado) Old Man Mountain Retreat Center property south of the summit.

Old Man Mountain resides entirely on private property. However, due to the peak’s status as a local landmark as well as a continued object of spirit quests, nearby property owners seem tolerant of hikers and spiritual pilgrims visiting this summit. Please do the summit-hunting community a favor and be respectful of local residents and property owners. Be quiet when passing by private homes and pick up after yourself.Additionally, though it may sound unusual to some of us, certain individuals visit this peak as part of a spiritual quest. Please be mindful of your behavior should you encounter visitors who may be hiking the summit for spiritual reasons.
