  • Distance: 3 miles one-way (4.8 m)
  • Elevation Gain: 1,083 feet (330 m)
  • Type of Trail: Out & Back

At 10,013 feet, Deer Mountain is encompassed in a forest of sweet-smelling ponderosa pines. Switchbacks ease hikers into the 1,083 feet in elevation gain. At the summit, you are rewarded with views of Longs Peak, Moraine Park, Upper Beavers Meadows, and Estes Park.

Ranger Recommendation: Be sure to be wary of parking availability and thunderstorms as Deer Mountain is both one of the most popular and lightning-struck mountains in the park.

Storm Warning: Weather in Colorado can turn in an instant! Be prepared for changing weather conditions. Check the forecast before heading out. Lightning can strike anywhere in Rocky. Watch for building storm clouds and return to the trailhead immediately if you hear thunder. As a rule of thumb, try to be back at the trailhead by noon.
