Super fun and easy hike at Horsetooth Mountain Park just outside Fort Collins, Colorado. Entry fee is $10 per vehicle per day, and annual passes are available. We did the Horsetooth Falls Loop, totalling 3.2 miles. 5,735 feet minimum elevation and 6,229 feet maximum elevation. The majority of the trail is lined with pine trees and there are some nice wide views as well. I would highly recommend this hike to anyone. Later, we stopped at JJ's Wood Fired Pizza for lunch, and enjoyed it thoroughly. https://jjspizzafoco.com/
