Hiking in the Rockies was a total blast! This was a perfect hike for anyone who is visiting the region, but not used to hiking in high altitude (like me). Robin was a great guide...very friendly and informative, with a good sense of the group's pace. We met beforehand, then drove up to the trailhead. It was about to start snowing, so she chose Mt. Falcon. We were literally hiking in the clouds! It was a gorgeous hike, along with being a great workout. I'd say the ability level was intermediate, and the snow required decent shoes. (No surprise in mid-January.) Four miles definitely feels longer at altitude, but Robin had the group take many water, trail mix, and photo breaks. I'll definitely book another experience with Hiking in the Rockies next time I'm in Denver!
