Confirmed from Steep Canyon 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.

Cardio trails around 2 Miles Suggest to wear hiking shoes !! It’s really steep no joking. The trail is actually connected to another grand view trail from another exit

★★★★☆ — Paprika , May 2022

Two miles loop trail. Rated intermediate or moderate. Not all place has shade. Hat, sun blocker and water are essential during hot summer. There are stairs, steep uphills and flats in this trail. Hiking shoes or shoes with good grips recommend for steep up/down hills.

★★★★☆ — Janice , Jun 2020

Beautiful trail. It’s a gem in the middle of Diamond Bar. Regardless of which trail head you choose, it will lead you to multiple trails and loop you back to where you started. It has some fairly steep inclines, but definitely worth the effort to get to the peak where you will find spectacular 360 degrees views.

★★★★★ — Esther , Feb 2023

Great get away hike right in Diamond Bar. You feel as you are in nature though only about 5 minutes away from everything. Hiking trail has good inclines for a nice little work out.

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.
