It is the highest peak in the Williams Fork Mountains and also the highest point in the Ptarmigan Peak Wilderness.  Coon Hill is located just west of the Continental Divide in Northern Colorado and is less than 1 mile northwest of the west end of the Eisenhower Tunnel of Interstate 70.  Coon Hill was once a popular summer hike; there used to be a summit register, but recent parking restrictions have made it less accessible.

The South Ridge route is second class and is 2.8 miles roundtrip with ~1,700' vertical feet of elevation gain. Whereas, the Northeast Ridge is third class and 3.2 miles roundtrip with ~1,640 vertical feet of elevation gain.

Coon Hill offers excellent spring skiing off the north, east and south faces. The following refers to the spring. Ascending from the south is not too difficult. It requires an easy skin to the South Ridge and up to the summit. Due to the steepness (35 degrees) this should only be skied when spring conditions exist.

Getting There

Exit I-70 westbound directly after the Eisenhower Tunnel and park on the north side of the highway (11160'). Do not park near the maintenance building. This makes the staff nervous. Head north about 0.4 miles and Coon Hill will be obvious on your left. More detail in "Colorado Mountain Hikes for Everyone - Routes and Maps to 105 Named Summits" by Dave Muller.

Children refers to the set of objects that logically fall under a given object. For example, the Aconcagua mountain page is a child of the 'Aconcagua Group' and the 'Seven Summits.' The Aconcagua mountain itself has many routes, photos, and trip reports as children.
