Confirmed from Mount Diablo state 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.

What runners say about Mount Diablo state park

Pulled from public reviews of this trail (4 of them) — the things people bring up again and again, in their own words. Nothing here is written by us.

9 miles loop from the overflow parking lot of Mitchell Canyon Parking lot Eagles Peak with 2,250 feet elevation gain of 4 miles then turn right (South/West) on Mitchell Canyon fire road to loop back down. Be extra cautious with lose gravel and narrow spine on the ridge of Eagles Peak trail.

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.
