Confirmed from Castlewood Trailhead'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.

What runners say about Castlewood Trailhead

Pulled from public reviews of this trail (16 of them) — the things people bring up again and again, in their own words. Nothing here is written by us.

Local trail, peaceful, well maintained, beginner/intermediate, some steep hills. Watch for bikes, considerate riders. Overall I enjoyed my hike😁

★★★★★ — Guadalupe , Jun 2022

There are plenty of shades and hills, so it's a great place for hiking and biking. 🚶‍♂️🏃‍♂️🚵‍♂️ 1. A walk east along Castlewood Dr leads to the Nora Kuttner Recreational Trail. 2. Follow the Castlewood Trail and it ends next to the Rosecrans Ave fire station. 3. Rosecrans Trail east to connect Parks Rd Trail. 4.

★★★★★ — Djkwan , Apr 2021

Easily accessible, the trails are wide and it's not that far away from houses at certain points in the trail but you definitely get that surrounded in nature feel from this trail.

★★★★☆ — Jessica , May 2023

Ran the 9-mile loop called "Parks Road, Rosecrans, Castlewood, and Juanita Cooke Loop" on allTrails on a rainy Friday morning in December. The trails weren't too muddy, and the route was easy to follow. Spent around 1.5 miles on Castlewood trail, going from Rosecrans and connecting to Nora Kuttner.

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.
