Confirmed from Mountainside 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 Mountainside Park

Pulled from public reviews of this trail (191 of them) — the things people bring up again and again, in their own words. Nothing here is written by us.

well-maintained 4 mentions

“Trails are well maintained and marked clearly.”

🪧 well-marked 5 mentions

“From there, a well-marked trail leads you over a few small streams and through two boy scout encampments before making the ascent up to top of the Pequannock Nob.”

Mountainside Park is an excellent park for hiking and exploring. The terrain is diverse and offers both well walked trails, as well as some tricky to navigate and steep rocky inclines. The trails are very well marked and easy to identify. Most of the trails link together into two large loops.

★★★★★ — Matthew , Feb 2020

Great easy to moderate hiking park. It offers different loop options. Please keep it clean.

★★★★★ — Anamaría , Apr 2025

Love this mountain! Well maintained and clean . Come more times to try all the trails definitely!!!! Att my hiking track FYI. I took yellow, orange, then blue trail this time. Parking lot is tiny, only fit for six or seven cars.

★★★★★ — Erin , Nov 2019

Pretty great moderate-length hike for a great overlook. We basically walked around the perimeter of the park through the blue, then orange, and then red trails. Note that there are kind of 2 overlooks.

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.

“The view from the summit is excellent; one of the best in the state, allowing a 180-degree view of Pequannock valley out to the NYC skyline.”
