Deer Mountain: A Half-Day Summit Hike

Overview

About Deer Mountain Trail

Why go

  • Mountain views begin before the long switchback climb.
  • The summit panorama reaches Longs Peak and the Mummy Range.

Heads up

  • A steady high-altitude climb starts above 8,900 feet.
  • Parking near Deer Ridge Junction is limited.
Deer Mountain Trail is a 6.2-mile out-and-back from Deer Ridge Junction to the summit and back, crossing open meadow country before a long switchback climb and a steep final spur. It reaches about 10,000 feet after starting around 8,930 feet, so this is a hard high-altitude half-day hike, not a quick viewpoint walk. Allow roughly 3 to 4 hours for the climb, summit stop and return. Plan on about 6.2 miles round trip; some published descriptions round it to 6.1. The listed gain is about 1,083 feet, though some route estimates count more as they include small dips and re-climbs. Go for the mountain-top panorama and views that begin well before it; skip it if you want an easy walk.

Trail guide

Hiking Deer Mountain Trail

Follow the summit lineThe first junction comes roughly 0.1 mile in.

The first junction comes roughly 0.1 mile in. The left fork heads toward Little Horseshoe Park and Aspenglen Campground; stay on the straight branch for Deer Mountain. Continue to the junction near mile 2.9, then turn right for the summit spur. The named trail also continues down toward Estes Park from here, but that is a different point-to-point route. For the summit hike, climb the final 0.2 miles, then return along the same line. This is the turn that prevents accidentally following the longer continuation.

Meadows and switchbacksThe path begins among ponderosa pines, then enters open country.

The path begins among ponderosa pines, then enters open country. Views across Little Horseshoe Park and the Mummy Range open on one side; Moraine Park, Longs Peak, Hallett Peak and the Continental Divide appear on the other. Deer and elk may be seen in the meadow, though sightings are never guaranteed. After the first mile, the route climbs steadily through switchbacks along the western slopes for about 2.2 miles. The tread is mostly natural ground, with constructed steps on the steeper sections. Near the summit junction the grade eases and drops roughly 100 feet before the final climb, so expect a little re-climbing.

The last climb and the viewThe summit spur climbs steeply for about 0.2 mile and 150 feet.

The summit spur climbs steeply for about 0.2 mile and 150 feet. A few trees stand near the top, but the view opens almost all the way around to Estes Park, Moraine Park, Longs Peak, Hallett Peak, the Mummy Range and the Continental Divide. A phone panorama fits this wide sweep better than one tight frame. Visibility matters here: the summit is the main payoff, and cloud can hide the distant view.

Deer Ridge Junction was once the site of Deer Ridge Chalet, a roadside resort that operated from 1917 to 1960. The complex included a lodge, cabins, restaurant, filling station and a 50-foot observation tower, plus a ski run descending into Little Horseshoe Park. The park acquired the property in 1960 and removed the buildings the next year. The busy junction is now mainly a trail access point, but that short-lived resort was once a destination in its own right.

Parking, winter footing and rulesParking near Deer Ridge Junction is limited, especially in summer, so arrive early.

Parking near Deer Ridge Junction is limited, especially in summer, so arrive early. No on-route water refill was confirmed; start with enough for the full climb and return. Winter traction devices are recommended, particularly after the first mile, while snowshoes are generally unnecessary. Snow and ice can make the switchbacks and final steps slower. Pets are prohibited on every trail in the park, so this is not a hike to bring a dog.
