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.
Frequently asked
- Is Glendale Open Space off-leash, and is it fenced?
- Off-leash and unfenced. This is open space rather than an enclosure, so recall needs to hold before the first visit.
- How long and how hard is the loop?
- About 1.6 miles of dirt trail with switchbacks and one climb, roughly 150 feet of elevation on a north-to-south lap. Shortcuts cut the distance for anyone hauling a wagon or a stroller.
- Is there water?
- No water on site, only bowls. Reviewers are consistent that everything a dog drinks has to come from the car.
- Is there shade?
- Very little. Two small huts and a stand of Gambel oak are the only real cover, so a hat and sunscreen matter more here than at a tree-lined park.
- What is at the parking areas?
- North and south lots, each with its own entrance, porta-potties and two electric vehicle charging stations. Trash goes in the lot dumpsters, since there are no cans along the loop.
