Hiking Heaven: Fort Collins' Top 7 Mountain Trails for Every Skill Level

If there's one trail that symbolizes Fort Collins outdoor culture, it's the 2.5-mile climb to Horsetooth Rock. I've hiked this trail in every season, and the 1,400-foot elevation gain still gives my knees a friendly reminder of their age. But that distinctive rock formation—visible from town and resembling, yes, a horse's tooth—makes the effort worthwhile.

The trail begins at Horsetooth Mountain Open Space (6 miles west of town) and winds through meadows dotted with wildflowers before ascending through ponderosa pine forest. The final scramble to the summit requires basic bouldering skills, but nothing technical. From the top at 7,255 feet, you're rewarded with panoramic views of Fort Collins, the plains stretching eastward, and the Front Range mountains to the west.

I typically pack my hiking poles for this one—they're lightweight but provide crucial stability on both the ascent and descent, especially for those of us with six decades of adventures in our knees. The cork handles absorb sweat better than plastic alternatives, which matters on hot summer days.

When I need to remind myself that age is just a number, I head to Greyrock Trail in Poudre Canyon. This 7.1-mile round-trip route with 2,200 feet of elevation gain separates the casual hikers from the committed ones. The trail begins about 15 miles up the scenic Poudre Canyon and offers two route options that form a loop at the top—I recommend taking the Meadows Trail up for its gentler grade and returning via the more direct Summit Trail.

The journey takes you through areas recovering from past wildfires, offering a sobering reminder of nature's cycles that resonates with my environmental law background. Near the top, you'll need to navigate some unmarked rocky sections where the trail becomes less obvious. I always bring my trail map despite having hiked this trail dozens of times—cell service is spotty, and the detailed topographic information has saved me from wrong turns more than once.

The massive granite dome at the summit provides stunning 360-degree views of the surrounding mountains and valleys. Pack a lunch and plenty of water—there's a perfect natural stone seat at the top that I've claimed as 'Skylar's Perch' over the years.

When I'm hosting friends visiting from lower elevations, Arthur's Rock in Lory State Park is my go-to trail. At 3.4 miles round-trip with about 1,000 feet of elevation gain, it's challenging enough to feel accomplished but accessible for most reasonably fit hikers.

The trail begins with a gentle meander through meadows where mule deer often graze, unbothered by human presence. As you climb higher, the path transitions into switchbacks through mountain mahogany and ponderosa pine. The final quarter-mile involves some rock scrambling, but nothing that requires technical skills.

The summit provides spectacular views of Horsetooth Reservoir below, which shimmers like a sapphire against the landscape. On clear days, you can see all the way to Wyoming to the north and Long's Peak to the south. I've spent many peaceful hours atop Arthur's Rock with my compact hammock strung between two sturdy pines, reading a good book or simply watching red-tailed hawks ride the thermals. This ultralight hammock packs down to the size of a grapefruit but sets up in minutes for mid-hike relaxation.

After your hike, I recommend stopping at nearby Vern's Place on Highway 287 for their massive cinnamon rolls—a tradition I've maintained for years despite my usual healthy eating habits. Some indulgences are worth it!

For wildlife enthusiasts, Coyote Ridge Natural Area offers a 4-mile out-and-back trail that climbs gradually through one of the region's best-preserved shortgrass prairie ecosystems. Located just south of Fort Collins off Taft Hill Road, this free trail (yes, FREE—music to a budget traveler's ears) provides spectacular wildflower displays from May through July.

The first mile is a gentle incline through prairie dog colonies where black-tailed prairie dogs stand sentinel, barking warnings as you pass. Keep your eyes peeled for raptors—I've spotted golden eagles, northern harriers, and red-tailed hawks hunting here regularly. The trail steepens as you approach the ridge, with about 750 feet of elevation gain total.

At the top, you're rewarded with expansive views of Horsetooth Reservoir and the Front Range. This is prime habitat for mule deer and coyotes, particularly in early morning or evening hours. I never hike here without my compact monocular, which offers 12x magnification while weighing less than my smartphone. It's perfect for spotting distant wildlife without lugging heavy binoculars.

This trail gets hot and exposed in summer afternoons—there's virtually no shade—so plan accordingly. After your hike, you're just minutes from Zwei Brewing, where their German-style lagers provide perfect refreshment. Their outdoor patio welcomes hikers (and well-behaved dogs), making it my favorite post-Coyote Ridge tradition.

One of Fort Collins' greatest charms is the proximity of world-class hiking to exceptional craft breweries. After three decades reviewing environmental impact statements by day and brewery offerings by night, I've developed a system of perfect trail-to-tap pairings.

After conquering Horsetooth Rock, head to Odell Brewing Company (just 20 minutes from the trailhead) for their 90 Shilling Amber Ale. The malty backbone and caramel notes complement the earthy experience of the trail. Their spacious patio is perfect for recounting summit adventures.

For Greyrock hikers, New Belgium Brewing's Fat Tire Amber Ale offers the perfect balance of toasty malt and hoppy refreshment. The brewery's commitment to environmental sustainability aligns perfectly with the conservation ethic needed to protect these trails.

Arthur's Rock pairs beautifully with Equinox Brewing's Space Ghost IPA, available at their cozy downtown taproom. The citrus notes cut through trail dust, while the brewery's intimate beer garden provides a perfect setting to rest tired legs.

I always carry my insulated growler in my car—this vacuum-sealed container keeps beverages cold for 24+ hours, meaning I can transport fresh draft beer back to my campsite or Airbnb without losing quality. It's an investment piece that's survived countless Colorado adventures with barely a scratch.

Remember: always have a designated driver or use Fort Collins' excellent bike share program to travel between trailheads and taprooms safely.

As a dedicated budget traveler, I've mastered the art of experiencing Fort Collins' outdoor playground without emptying my retirement account. The city offers several affordable accommodation options that provide easy trail access.

For solo travelers, the Solarium International Hostel offers private rooms from $65/night or dorm beds around $35. Their communal kitchen helps cut costs further, and the garden setting attracts like-minded outdoor enthusiasts with valuable local trail knowledge. I've stayed here at least a dozen times and always meet interesting hiking companions.

If camping is more your style, Horsetooth Reservoir has several campgrounds with sites ranging from $20-30/night. Reservation fees apply, but the sunrise views and immediate trail access make it worthwhile. My inflatable sleeping pad has transformed my camping experience—it packs down to the size of a water bottle but provides three inches of cushioning that my 60-year-old back appreciates after a day on the trails.

For budget-conscious access to trails, purchase a $45 Larimer County Annual Pass if you'll visit for multiple days—it quickly pays for itself versus daily fees. The Fort Collins library also offers free State Park passes you can check out for the day (limited availability).

The city's excellent bike infrastructure means you can reach many trailheads without a car. The FCBikes program offers affordable rentals, and the local bus system accommodates bikes on front racks.
