Popular around Horsetooth Mountain Open Space
Horsetooth Rock is an iconic landmark in the Fort Collins area. To get to the summit you must dismount your bike and complete a short scramble here up to the summit. Although the scrambling is relatively easy, it is a little exposed in places and there can sometimes be loose gravel over bare rock faces. Just move carefully, deliberately, and don't be afraid to slide on your butt on the way down! After scrambling up, you get fantastic panoramic views from this long, exposed rock summit of the surrounding area. You get especially great views of Horsetooth Reservoir, which is named after the formation you're standing on. Since the summit is fairly large, even on crowded days you can usually find a spot to eat a snack and take photos away from other people. As you explore, just be aware of steep drop offs, large gaps between rocks, and loose gravel over bare rock.

Horsetooth Falls is a 20 foot waterfall in the heart of the Horsetooth Mountain Open Space. At the base of the falls the water collects in a large pool and flows into Spring Creek. There are a few seating areas where you can relax and take in the great views and cool off in the mist on hot days. You can go behind the falls, but be aware of wet rock. There is also a trail that leads to the top of the falls.

After passing a large, crumbly rock formation the trail trends steeply upward. After climbing some wooden stairs you are rewarded with a great overlook, which is a nice spot to stop and sip some water before continuing on to Horseshoe Rock.
