Glendale Open Space Trail
A 1.6-mile off-leash loop through Lone Tree prairie
About this park
Glendale Open Space is a 1.6-mile off-leash trail loop in Lone Tree with natural terrain, switchbacks, and resting spots shaded by Gamble Oak. It feels wilder than a typical fenced park; trails wind through open space with a small pond along the route. The updated parking lots offer two entrances and portable restroom facilities. The I-25 noise is audible but does not overwhelm the natural setting.

Before you go
This is a trail, not an enclosed park; keep recall solid before visiting. The switchbacks and natural terrain make it especially good for dogs that prefer exploration over circle running.
