Confirmed from Ketner Open Space's own listing, the park or land manager's website, and runner reviews. Blank cells mean we could not verify that fact — we would rather say "not reported" than invent one. There is no Easy / Moderate / Hard rating on this page on purpose: a one-word difficulty score tells you nothing about whether a trail suits your run. Surface, distance, shade and hours do.

“A nice little lake with a path around it which is great for a jog or dog walking.”

Such a beautiful place to walk! You may be lucky to spot a good sunset or some amazing wildlife, like cranes and turtles. Dog owners beware though- I've spotted a coyote on more than one occasion, too.

★★★★★ — Sara , Dec 2023

Ketner Lake is a nice neighborhood attraction for the city of Westminster. Right off of 104th and Wadsworth it features a nice 1.5 mile walking trail that encompass the whole lake. Plenty of trees and benches around the perimeter ensures that your visit is a pleasant one if you choose to walk the trail.

★★★★☆ — Christian , Mar 2022

Easy access for a quick hike or some close by fishing. Check out the totems... You won't see that very often.

★★★★★ — Brian , Jun 2017

Peaceful, pretty, groomed trail. I have encountered coyotes. Good place to bird watch.

Trail conditions & character

What this trail is actually like underfoot and overhead, taken from its own listing and from reviews. Each one links to every other trail with the same character. Busy or quiet is reported as a plain fact, not a plus or a minus — a runner heading out alone at dawn often wants company on the path, and someone running intervals wants an empty one.
