Confirmed from Summitridge Trail'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.
Hiking area known for a dog-friendly trail that's long and has some steep inclines.

6/24/2022 My first time to visit Diamond Bar Summitridge Trail in California.

Rural Diamond Bar at it's best. Excellent trail system, only concern as other posters have mentioned is for signage as to what trail goes where...some are definitely not the correct trail. Fantastic distance views and the lower canyon trail is stunning.
Very quiet hiking trail, dog friendly and parking is free. Beautiful view up the hills where you can see the freeway from where you stand. The trail itself is moderate yet quite long, just beware with snake from the bushes specially on warm/hot season coming soon on summer.
I started at the top by the Diamondbar center parking lot & went clockwise around the perimeter of the hike. A nice up hill by steep canyon
