We'e been twice with our 10 month old pup, and he had a wonderful time romping with other dogs. Didn't take him long to learn to come back to us (w/ training treats in hand) or when we stopped to talk to other dog walkers. Nice fenced area with room to roam as well as a 1.6 trail with dogs on leash. Picnic table and small benches available as well as porta potty. Not difficult to get to at all once you drive there.

FYI: Glendale Farm Open Space Dog Park is a 5 acres secured, fenced off-leash dog park. OUTSIDE of the dog park boudaries is the Glendale Farm Open Space Trails and is not fenced.

When the dog park is dry and not full of mud, GFOS is a wonderful park for dogs. It is very beautiful, full of grassy areas, dirt, brush with little nooks and cranies for your dog to explore(or hide) and small hills to boot.
The park is adjacent to I-25, but I-25 doesn't pose any danger to the dogs within the park. Currently, CDOT and Douglas County is literally transforming the outer bounderies of GFOS along I-25. I don't plan to return to the park until the spring when most of the major construction is complete and the wet sloppy mud has dried up. Currently, the park is tricky to get to off the freeway ramps, but when the project is complete it should be much easier to access and more user friendly to vehicles.

There is a nice sized parking lot, or for better words, a dirt area for cars to park.

Always watch out for dog droppings, as many owners are unable to see their dog(s) pooping since it is so large and many dogs "run off" ahead of the owners(no fault of their own) out of sight for a few minutes.
