Deer Mountain - 6.0 Miles Round-Trip

Deer Mountain (10,013') caps a tall, divisive ridge between Beaver Meadows (south) and Horseshoe Park (northwest) in Rocky Mountain National Park. This moderate hike follows a well-maintained trail through ponderosa parks, aspen stands and subalpine forests to the summit, which rises just above all other points on the ridge.

Southern exposure keeps the trail snow-free longer than many others in the Park, extending accessibility from late spring to early winter.

Visitors will enjoy ecological diversity and panoramas that include some of Rocky Mountain's most iconic summits, meadows and geological features:

The Deer Mountain Trail heads east on a steady grade across sparsely treed hillsides of ponderosa and aspen. Deer and elk are common along these lower slopes, and southern views over Longs Peak, Beaver Meadows and Moraine Park improve with each step.

Moraines separating these meadows - or low ridges of glacial till pushed aside by a glacier's downward movement - gain definition as you progress.

The trail switchbacks at .85 miles with views over Horseshoe Park and the Mummy Range including Mount Chapin (12,454'), Mount Chiquita (13,069'), Ypsilon Mountain (13,514') and Fairchild Mountain (13,502').

Switchbacks steepen through 1.55 miles (9,612') in a thicker mix of aspen, spruce, and fir before leveling abruptly on the ridge top (2.05 miles : 9,835').

Travel eases through 2.25 miles (9,930') before dipping and climbing back to the Deer Mountain Summit Trail split (2.8 miles : 9,843'). Bear right for a short but steep climb to the summit.

The Deer Mountain summit (3.0 miles : 10,013') is small but easily maneuvered for sensational panoramas that stretch across Estes Park, Longs Peak and neighboring summits on the Continental Divide, Moraine Park, Beaver Meadows, Horseshoe Park and the Mummy Range.

A good map will help identify all points of interest, and provide useful perspective on the greater landscape and distance between each feature.
