Arapahoe open space wheels have to share the trail
A Porch Note from Colorado Porch — plain-English local details for all 64 Colorado counties.
Wheels are welcome on most Arapahoe County open space, within limits. Bicycles and some electric mobility devices are allowed on roads, parking lots, trails, and pathways unless a sign at that spot says otherwise. So the default leans toward access, and posted signage is what narrows it.
The second half of the rule is where it earns its keep. Riders must yield to pedestrians and equestrians where required, and trail speed limits apply alongside that duty. A bike rounding a blind bend at speed is the classic problem these rules head off, especially near a horse, which can bolt at a fast, quiet approach it never heard coming.
What worked at another park does not transfer cleanly, since the posting and speed rules are set trail by trail. Reading the signs at the start of the route, slowing where sightlines are short, and giving walkers and riders the right of way covers nearly every situation you will meet. When a stretch of trail feels genuinely unsafe, the county open space rules give you something concrete to point to rather than a hunch.
