Trail Guide (What I Actually Do)

Easy Bear Creek Trail (2.2 miles)

My take: This is the go-to for families or when you want a gentle walk with creek crossings are shallow (ankle-deep in summer), but wear shoes you don’t mind getting wet. Best in late spring when the cottonwoods are leafed out.

Moderate Sawmill Trail (1.8 miles)

My take: Less crowded, more of a hike. Goes up through pine trees to some old mill structures. Better views, but watch for mountain bikers on the descent. I prefer this one in the fall when the aspens turn yellow.

Local Trail Strategy (From Regular Use)

  • Combine both trails for a 3.5-mile loop (my usual)
  • Water: No fill stations—bring twice what you think
  • Footwear: Trail runners OK. Boots better if creek is high

Visitor Reviews & Public Feedback

“Perfect spot for a short hike with the dog. Parked at 7:30 AM on a Saturday and had the creek trail mostly to ourselves. Bring water—no sources on the trail.”

— Mark from Lakewood

“We saw three deer drinking from the creek in the first half mile. My 10-year-old loved the ‘adventure’ of the creek crossings. Not stroller-friendly though.”

— Sarah, Denver parent

“Best fall foliage within 30 minutes of Denver. Parking lot fills early on weekends – arrive by 8 AM or stick to weekdays.”

— James R.

Common Questions

Nope, it’s free. Jeffco parks don’t charge for day use. Just parking—and that’s free too.

Yes, on a 6-foot leash. No off-leash areas. Watch out for hot pavement in summer. Bring waste bags—none provided.

It’s decent if you like small brown trout. You need a Colorado license (available at Walmart or online). Best spots are below the bridges.

Sometimes at the parking lot, then it’s gone. I usually tell people: download maps offline before you go.

Yes! Winter hours are shorter (7 AM – 5 PM). The park may close if trails are icy or unsafe. Check the official site before visiting in winter.

The main parking lot and some trail sections are accessible. The Bear Creek Trail has flatter sections near the parking lot. For detailed accessibility info, contact Jefferson County Parks directly.

No, this is a day-use park only. For camping, try nearby Bear Creek Lake Park or Golden Gate Canyon State Park.

No, drones are not permitted in Jefferson County parks. This protects wildlife and visitor privacy.

Keep your distance, especially from deer. Never feed wildlife. If you see something unusual, report it to the park office. Remember, bears are rare but possible.

Spotty at best. Verizon tends to work best near the parking lot. AT&T and T-Mobile customers should download offline maps. Don’t rely on service for emergencies.
