The hike
The walk starts at Deer Ridge Junction, where US 36 meets Trail Ridge Road inside the park; parking is limited and there is no shuttle. The trail heads east through ponderosa pines and climbs a series of switchbacks up the west side of Deer Mountain, with views across Little Horseshoe Park to the Mummy Range. It levels off near the top, and a short, steep spur leads to the summit, at about 10,000 feet. From there you look over Estes Park and Moraine Park to Longs Peak, Hallett Peak and the peaks of the Continental Divide. Return the same way.
It is 6.1 miles (9.8 km) round trip with 1,200 feet (367 m) of climbing; allow about 3½ hours. The grade is Moderate: a steady climb on a good trail, with a steeper pull at the end.
The summit is open, and thunderstorms are common on summer afternoons: start early and head down if storms are building. Outside summer, expect snow or ice on the trail. Pets are not allowed on park trails. From May 22 to October 12, 2026, a timed entry reservation is needed to enter the park between 9 a.m. and 2 p.m.
Parking at Deer Ridge Junction is limited, so arrive early.
