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.

Glendale Open Space Trail reviews
What visitors consistently sayReviewers love the wide-open prairie views, the switchbacks through Gamble Oak, and how much room there is for dogs to explore and socialize. The recent updates (north and south parking lots, porta-potties, and paved sections up top) get consistent praise.
Most visitors describe the crowd as friendly and the pet owners as mostly responsible, with regulars happy to share the trail with newcomers.

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.
