Hit the Trails: Essential Hiking In and Around Fort Collins
The foothills west of Fort Collins are a hiker’s playground, offering everything from gentle strolls to lung-busting ascents. Preparing properly is key, as the Colorado sun and elevation can challenge even experienced explorers. This is our essential guide to hitting the trails safely.
For Beginners: Horsetooth Falls & Arthur’s Rock Trail
If you’re new to the area or just want a rewarding hike without a massive commitment, these two are perfect. Horsetooth Falls is a relatively easy 2.2-mile out-and-back trail that leads to a lovely seasonal waterfall. It’s a great choice for families and those still acclimatizing.
For slightly more of a challenge with a spectacular payoff, head to Arthur’s Rock Trail in Lory State Park. This 3.4-mile round trip involves a steady climb and a final rock scramble, but the panoramic views of Horsetooth Reservoir and the plains are worth every step.
For a Challenge: Greyrock Mountain Trail
Ready to test your legs? The 7.1-mile loop to the summit of Greyrock Mountain in the Poudre Canyon is a Fort Collins rite of passage. You’ll gain over 2,500 feet in elevation, navigating steep switchbacks and a final scramble to the top.

A little knowledge goes a long way in preventing a great day from turning sour. Understanding how to things to do in Fort Collins in the summer safely means being prepared for the unique challenges of the region. Here are some common problems and how to solve them.
Weather Woes: Navigating Afternoon Thunderstorms
One of the most common problems is the afternoon thunderstorm. Sunny mornings often give way to dark clouds, lightning, and hail by 2 or 3 PM. The solution is simple: start your adventure early.
If you’re hiking a mountain, aim to be off the summit and below the treeline by noon. If you see dark clouds building or hear thunder, turn back immediately. Don’t wait. Lightning is a serious danger in the high country.
Wildlife Encounters: Staying Safe Around Bears, Moose, and Snakes
You are a visitor in their home. Keep a safe distance from all wildlife. Never feed wild animals. Black bears are common; make noise while you hike so you don’t surprise one. If you see a bear, do not run. Stand your ground, make yourself look big, and back away slowly.
Moose can be more dangerous than bears. If you encounter one, give it a very wide berth. Rattlesnakes are present in the foothills; watch where you step and listen for their distinctive rattle.
Altitude Acclimatization Tips for Visitors
Fort Collins sits at 5,000 feet, and the nearby trails quickly climb higher. If you’re coming from sea level, take it easy for the first day or two. Drink lots of water, avoid heavy alcohol consumption, and listen to your body. Headaches and fatigue are early signs of altitude sickness.
