Confirmed from Pecos Park'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.

“Basketball hoop, doggie bags, playground and swings, bences, shaded pavilion to eat 👍”

This park is really pretty!! It's hilly with lots of trails, trees and nice picnic tables. The playground looked pretty nice too. We don't live nearby, but met up with family at a convenient location. I specifically picked it for having lots of trees, and it did not disappoint.

★★★★☆ — Michele , Oct 2020

Nice quite little park. Covered area for gatherings, small skateboard section, plenty of trees and shade. Small stream cutting through the grounds. Never overly crowded. I visit there on my way through riding the bike paths.

★★★★★ — Blueharley86 , Nov 2022

Nice little park. Not much here other then a pavillion with picnic tables(no grills), a play ground and a couple benches. Well maintained grounds and paths.

★★★★☆ — Russ , Jun 2019

I love this park. It's big with big shade trees and hills. It's at the start of a walking trail with 6 foot sidewalk paths.

★★★★★ — Alanna , Aug 2022

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.

“There is a great playground (notably in my mind, it has tons of swings), there are wonderful climbing trees, and there are huge and grassy hills to roll down.”
