Confirmed from Memmen Ridge 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.

🏞️ beautiful scenery 4 mentions

“That being said, it is a great trail and full of flowers and gorgeous trees.”

👟 good for all levels 2 mentions

“Good, easy hike - would benefit from improved trail maintenance and signage, which is generally a benefit enjoyed at most CR open space trails.”

Great family and pet hike. My six and seven year old had no problems. Stay on the dirt trail as there is cactus 🌵 everywhere.

★★★★★ — Megan , Oct 2020

Overall it is a decent single-track trail made up of rock, dirt, and some sandy-type areas. It could use a little maintenance, some of the weeds are growing into/ over the path. Because the path is very narrow, I am glad we did not encounter anyone else until the end of our hike.

★★★★☆ — A , Aug 2025

Nice ez walk in town. It feels far removed but it's nestled among housing and a school. The trails are very easy. It's a great family hike. Just a short distance away if you live in Castle Rock it's a hop skip and a jump. I will definitely come back sometime.

★★★★★ — S , Jun 2022

Love to take my dog for walks here on the weekend in the summer. It's a fun and easy day hike.

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.
