Simply put, Mount Zirkel is one of the best mountains in Colorado. At 12,180 feet, it is the high point in Colorado's Park Range, Routt County, and its namesake wilderness. It also ranks number fourteen among Colorado's most prominent peaks. A decent number of accolades for a mountain in a state which contains over 1,000 higher peaks.

German geologist Ferdinand Zirkel did some work in the area and his name is attached to the mountain and the wilderness that encompasses it. A fitting name for an area with some geologic character. Glacially carved cliffs lead upwards to broad alpine plateaus larger than maps would lead one to believe. Lower down, streams, lakes, and meadows are the rule and make the wilderness a popular destination for hikers, fishermen, and hunters.

In 1997 a severe wind event blew down millions of trees in the area. Forest fires and an epidemic of pine beetles soon followed. Some trails in the area are still affected by the downfall. Standing victims of the fires and beetles abound. The large number of beetles in the trees has also made the area a popular destination for woodpeckers who can be observed working their unique craft.

The normal route for climbing Zirkel is an approach up Gold Creek to Red Dirt Pass and then a hike over the peak's summit plateau followed by a short class two scramble to the top. Other approaches to the plateau are possible from different drainages to the east and west. The north ridge looks like it would go with a bit of tougher climbing right at the top. The east and west faces harbor potential for steep climbs on snow and rock.

Getting There

Slavonia Trailhead

From Steamboat Springs head two miles NW on US 40 to CR 129 (Elk River Road) and turn right at the stoplight. Head about eighteen miles north, past Clark, to Glen Eden, and turn right again at Seedhouse Road ( AKA CR 64 and FR 400) and follow the road and signs ten miles to the trailhead. Seedhouse Road is passable for passenger cars to the trailhead.

Routes Overview

Mount Zirkel offers a variety of routes that will suit hikers and climbers of various experience levels.

The standard and the easiest route to Mount Zirkel is the Slovenia Basin/Red Dirt Pass Route. While this route has few technical difficulties, it does have two river crossings which can be very challenging into early August.

This route is class 2 in difficulty and 17.2 miles round trip with about 3800 feet elevation gain. See the route page for details.

The second most popular and second easiest route up Mount Zirkel is the Gilpin Creek Route. This route is slightly shorter and slightly harder than the Slovenia Basin/Red Dirt Pass Route. From Gilpin Lake, this route climbs Point 12006 and then follows the ridge north to the summit.

Other Routes

Red Dirt Pass can also be climbed from the east via the little used Frying Pan Basin trail and route. Much of the trail has faded away, but it would be a good route for those seeking solitude.

The West Face of Mount Zirkel offers many steep snow and ice couloir routes as well as many fine rock climbs. Unlike most other ranges in the area, the rock here is relatively solid and many spectacular, but seldom done rock routes have been established here.

The East Face also holds potential for more difficult routes as well, but doesn't appear to be as solid as the west face.

When To Climb

August and early September is the most popular time to climb here. July is fine too, but this area gets more snowfall than anywhere else in Colorado, so winter snows tend to stay late and through most of July. Stream crossings can be very problematic in June and July.

June and July would be the ideal time of year for the west side couloirs and other snow routes.

Fall is a fine season as well, but wear blaze orange during the hunting season. Big snowfalls usually don’t come until late September or early October.

Winter ascents of Mount Zirkel are certainly possible, though it’s a long trek in when the road is closed. Because of heavy snowfall, trail breaking will not be easy and be aware of avalanche danger. For the well prepared climber, a winter ascent would prove a worthy challenge.

There are several developed campgrounds along Seedhouse Road for those making the standard approach.

Gold Creek, Slovenia Basin and Gilpin Creek all have good campsites, but camping is not allowed within 1/4 of a mile of Gold Creek Lake and Gilpin Lakes.
