I picked Saint Vrain Mountain somewhat at random from a hiking site, not really knowing what to expect other than it was a good climb (3,200 ft over 10 miles). The trailhead was back behind Allenspark, a bustling metropolis of 433 people, not far from Estes Park and Rocky Mountain National Park.
I was pleasantly surprised to discover that the hike was absolutely gorgeous! The trail was lined with golden aspen all throughout treeline, then once we were above treeline we were treated to amazing views of the front range and eventually Wild Basin in Rocky Mountain National Park! The trail followed the border between the Indian Peaks Wilderness Area and Rocky Mountain National Park and offered amazing views of Longs Peak and other peaks nearby! St. Vrain Mountain isn't particularly exciting, but it offered an amazing view!
It was a LONG hike, but incredibly rewarding.
