Confirmed from Sunset Ridge 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.

A good place for a decent workout. The parking space is limited. You will have to park in the residential area nearby. That will add around half a mile to the hike.

I had plan to go to the fall but the google maps took me here. Very nice view and moderate trail. Because i was looking for a way to go toward the fall I lost the miles that I hiked. There were limited parking spots between ten to 15 cars. It should be easy for kids older than 8 and intresting.

★★★★★ — Amir , Aug 2020

AMAZING! A very steep trail I might add. We only did 3.5 miles, only half of the trail. The trail is very narrow and rocky. I highly recommend to wear good hiking shoes because it can be a bit slippery. The best part was the views of the mountains and how quiet and serene it looked.

★★★★★ — Monica , Mar 2021

Had a good time here with a good friend of mine, it's like free therapy when you arrive walking and listening to nature you become one. The people are real friendly when you pass them or see them they greet I will definitely come back on my own to take more harder paths and a One on one with nature.

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.
