Hiking in Fort Collins is one of the best ways to enjoy fall. Crisp air, color in the trees, the scenic trails we’re lucky to live next to. But the same weather that makes the season worth chasing — wet leaves, cold rocks, freeze-thaw mornings — turns easy trails into ankle-twisting hazards.
The injuries we see most this time of year are preventable. Here’s the playbook.
Why fall trails get more dangerous
A few seasonal factors stack up:
- Wet leaves cover roots, rocks, and uneven ground
- Morning frost makes rock surfaces unpredictable
- Shorter daylight pushes hikers into low-light terrain on the descent
- Layering changes core temp throughout the day, which affects how your body responds
The combination is what gets people. A trail you’ve walked dozens of times moves differently in October.
The most common fall hiking injuries
Ankle sprains. The big one. Lateral rolls from stepping on a hidden root or angled rock.
Knee strain. Long descents on uneven terrain put the patellar tendon and the IT band under sustained load.
Lower back tightness. Long days under a pack, especially on uneven ground, light up the low back by mile four.
Hip and glute strain. Sustained sidehilling forces the hip stabilizers to work harder than they’re conditioned for.
What to do before the hike
Five minutes of prep work prevents 90% of what we see:
- Single-leg balance work, eyes closed, one minute each side
- Calf raises, especially with the heel hanging off a step
- A few sets of glute bridges or hip airplanes to wake up the stabilizers
- A short dynamic warm-up before the trailhead — not at the parking lot scrolling your phone
What to do on the trail
- Trekking poles on descents. Especially with a pack. Cuts knee load by 25 to 30%.
- Eyes ten feet ahead, not at your feet. Lets you plan footing.
- Slow on wet rock and root crossings — the time you save isn’t worth the recovery.
- Layer down before you sweat through a base layer. Cold + wet is when pulls happen.
When to see a PT
If you’ve rolled an ankle that’s still tender after a week, or you’re noticing recurring knee or low back tightness on the trail, that’s the moment to address it. Hiking season is too short to spend it on the bench.
Frequently Asked Questions
Why are fall trails more dangerous for hikers?
Wet leaves hide roots, rocks, and uneven ground; morning frost makes rock surfaces unpredictable; shorter daylight pushes hikers into low-light terrain on the descent; and layering changes core temperature through the day. A trail you have walked dozens of times moves differently in October.
What are the most common fall hiking injuries?
Ankle sprains are the big one, usually lateral rolls from a hidden root or angled rock. We also see knee strain from long descents on uneven terrain, lower back tightness from long days under a pack, and hip and glute strain from sustained sidehilling.
How do I prepare for a fall hike?
About five minutes of prep prevents most of what we see: single-leg balance work with eyes closed for a minute each side, calf raises with the heel hanging off a step, glute bridges or hip airplanes to wake up the stabilizers, and a short dynamic warm-up before you start.
