About this park

The Boneyard at Reliance Park is an unusually large off-leash park in Erie, with three separated sections, an interior walking loop, and a rare-for-Colorado grass-and-foliage surface instead of all gravel. Reviewers routinely call it the biggest dog park they've been to, with agility setups in one section and a shaded small-dog area.

The Boneyard at Reliance Park reviews

What visitors consistently say
The highlights

Reviewers lead with the scale, then the grass-and-foliage surface instead of the usual gravel. The three separated sections (main, small-dog, and a third with agility equipment) are what makes The Boneyard's layout work, and the interior loop lets owners put in steps while the dogs run.

The community

A pride-of-place community: multiple reviewers describe regulars picking up stray poop around the park on their own. The compostable waste bag program is a visible sign the town takes the space seriously.

Before you go

Water dishes can become mud pits quickly if a dog knocks one over, so bring a towel and expect some clean-up for rollers. It's about 30 miles from Denver but worth the trip for the size.

Frequently asked

Is The Boneyard fenced, and are the areas separated?
Yes. Three separated sections split the space: a main run, a small-dog area with benches, and a third holding agility equipment.
Is there water and shade?
Water dishes sit around the grounds and there is some shade, including a shaded bench in the small-dog section. Bowls do get knocked over, and the spill turns the ground underneath to mud.
Is there a walking path for owners?
A loop runs around and through the park, so a visit doesn't mean standing in one spot for an hour. Reviewers mention getting their steps in while the dogs range.
Are waste bags provided?
Yes, and they're compostable, with dedicated collection containers for them. Reviewers describe regulars walking the grounds picking up messes that aren't theirs.
How far is it from Denver?
About 30 miles, out in Erie. Several reviewers make that drive anyway and rank it their favorite in the Denver area.
