Stretching roughly 13 miles along the eastern edge of the Front Range, the Foothills Trail is Fort Collins’ ridge-line singletrack: exposed grass- and shrub-covered slopes, bands of sandstone outcrops, and wide views that open toward Horsetooth Reservoir and the city below. The trail functions as both a local commuter spine between multiple natural areas and a compact, satisfying day ride for riders who enjoy rocky, technical sections, punchy climbs and long exposed descents. Because much of the route is on city natural-area land or on trail easements that skirt county-managed parkland, the experience is a mosaic of different takes on “foothills” terrain rather than a single, uniform trail.
Getting there and access
There are several commonly used access points. A convenient entry is along Overland Trail (Road 42C) near the south end of Colorado State University’s Hughes Stadium; park on the north side of the road and find the trail on the stadium’s southwest flank. The route also parallels County Road 23 (Centennial Drive) along the east side of Horsetooth Reservoir for riders who prefer to start closer to the water. Because the Foothills Trail crosses city-managed natural areas and corridor easements that touch Horsetooth Reservoir County Park, parking rules, gate hours and vehicle restrictions may vary by lot — confirm official lot hours and any seasonal closures before you go.
Route and riding character
Expect mostly singletrack with rocky sections, short technical moves, and sustained exposure. The tread alternates between rocky, bench-style track and firmer gravel connector segments; some descents are steep and fast where the trail drops toward reservoir-access roads or the stadium area. The north–south orientation and open slopes mean wind can be a factor, especially on exposed ridgelines. Fitness and handling matter here: climbs are often punchy rather than long, and the reward is a series of scenic downhills. The trail also contains short spurs — including the Michaud/Claymore Lake spur — that make natural turnaround points or add a bit of water-side scenery to the ride.
Scenery, seasons and what to expect on the trail
Views are the route’s headline: from the high points you can see Fort Collins, the stepping profile of the foothills, and Horsetooth Reservoir tucked into its bowl. Vegetation is predominantly shortgrass, mountain mahogany and sage; trees are sparse, so shade is limited. Spring green-up and late summer wildflowers can brighten the slopes, but the trail is most exposed and dry during summer and early fall. Winter brings snow and icy patches at times; if conditions are uncertain, check with the City of Fort Collins Natural Areas or Larimer County for seasonal advisories before planning winter travel.
Connections, loops and ride-building
One of the Foothills Trail’s strengths is how it stitches together multiple natural areas: Pineridge (with Dixon Reservoir), Maxwell and Reservoir Ridge. Use the trail as a point-to-point across the foothills or combine spurs and cross-connections to make loops of varying lengths — the Dixon Reservoir loop and the Michaud/Claymore Lake spur are two common options for shortening or sweetening the route. If you prefer an out‑and‑back, plan your turnaround around available parking or arrange a shuttle; several access points make flexible routing possible.
Safety, trailcraft and etiquette
Because the trail is exposed and often rocky, pack sun protection, extra water and a basic repair kit. Tread can be loose on descents and steep pitches — pick conservative lines if traction is poor. The Foothills Trail passes through city natural areas and county-managed parkland, so observe posted rules (pets, fire restrictions, motorized vehicle prohibitions) and respect seasonal closures or habitat-protection signs. Yielding follows standard singletrack etiquette: riders traveling downhill generally have the right of way, and slower users or hikers should be given space. Cell coverage can be patchy in the foothills; tell someone your plan and expected return time for longer rides.
Local context and stewardship
The Foothills Trail is part of Fort Collins’ municipal natural-area network and runs through or alongside several named natural areas (Pineridge, Maxwell, Reservoir Ridge). The city’s Natural Areas program maintains much of the corridor and publishes route maps and management guidance; Larimer County manages Horsetooth Reservoir lands adjacent to parts of the trail. Because sections of the route cross easements and different jurisdictional parcels, volunteer stewardship groups and trail partners occasionally coordinate maintenance and improvements — consider joining a local volunteer day if you’d like to give back.
Getting there
From the Overland Trail-Rd 42C intersection in Fort Collins, take 42C west towards the south end of CSU Hughes Stadium. Park on the north side of the road. The trail is on the right (north) side of the road on then SW side of the stadium, and is a gravel road that quickly turns into singltrack. On the south side of 42C is a trail into the Pine Ridge Natural Area and Dixon Reservoir. This trail can also be accessed from Road 23 that follows the east side of Horsetooth Reservoir.
Frequently asked questions
How long and difficult is the Foothills Trail?
The Foothills Trail is about 13 miles end-to-end and is typically rated advanced due to rocky sections, exposed climbs and technical descents. It’s a good fit for experienced riders comfortable with loose rock and punchy climbs.
Where are the main trailheads and parking areas?
Common access points include the Overland Trail (Road 42C) area near Hughes Stadium and parking areas along County Road 23 near Horsetooth Reservoir. Parking rules and hours can vary by lot—check the managing agency’s current information before visiting.
Can I connect to Dixon Reservoir or Claymore Lake?
Yes — the Foothills Trail connects with Pineridge Natural Area and the Dixon Reservoir loop, and there are short spurs (such as the Michaud/Claymore Lake spur) that provide access to small water bodies and additional loop options.
Is the trail shaded or suitable for hot-weather riding?
Much of the route is exposed with limited tree cover, so temperatures and sun exposure can be significant in summer. Carry plenty of water, wear sun protection and consider early-starts or shoulder-season rides to avoid peak heat.
Are dogs and mountain bikes allowed?
Mountain biking is a primary permitted use across much of the Foothills corridor; dogs and other uses are governed by the specific natural-area rules (for example leash requirements). Confirm regulations for the specific section you plan to use with the City of Fort Collins Natural Areas or Larimer County.
A 13-mile, point-to-point singletrack that threads Pineridge, Maxwell and Reservoir Ridge natural areas, the Foothills Trail serves up exposed ridgelines, rocky tread and sweeping views of Horsetooth Reservoir and Fort Collins. Technical enough to keep experienced riders honest, it also links to shorter loops and reservoir access — but expect sun, wind and limited services along the way.
