Beaver Mountain is a relatively small peak for Rocky Mountain National Park standards. However, the standard approach from Upper Beaver Meadows Trailhead requires over 2200 feet of gain, much of which is off-trail.
The peak rises from the western end of Beaver Meadows, the name which has also been applied to the park entrance and visitor center on US 36 on the east side of the park. Beaver Brook, which meanders through Beaver Meadows, originates on the north side of Beaver Mountain.
Beaver Mountain is easily seen from US 36 and US 34. Millions of people see it every year as they drive through the park, but relatively few take the time to reach the summit.
Beaver Mountain is ranked 111 out of 126 on Mountain Jim's Summits of Rocky Mountain National Park List. It is unranked on Gerry Roach's Rocky Mountain National Park Summits List because the prominence above the saddle connecting it with Tombstone Ridge is not at least 300 feet (it is 231 feet).
The summit is forested, but views of Longs Peak and the peaks of the Continental Divide and Mummy Range can still be had from between the trees.
