We have not been able to confirm the surface, distance or shape of Allamuchy Mountain State Park, Deer Park yet from its own listing, the park's website or runner reviews — so those cells stay blank rather than guess. What is below comes straight from the listing and from reviewers' own words. 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.

“If you love a quick and easy hike with your kids or a pet, this is the place to go.”

Adventurous!!! If you love a quick and easy hike with your kids or a pet, this is the place to go. I have a 11 month old Rhodesian Ridgeback who need to let out some energy and this place did the trick. Think it's going to be way to rocky? Think again, you have the option.

A simple and straightforward hike; a less popular part of Allamuchy Mountain State Park. Good for avoiding crowds of people lol. The pond is nice. White trail and yellow trails are narrow and sometimes thorny plants get in the way, but once you hit blue, nice and wide open trails.

★★★★☆ — Eric , Oct 2020

Great place for a hike, multiple trails. The main path, easy hike. The other trails are more difficult.

★★★★★ — Judy , Jun 2018

Deer Park...Great Mt bike trails for beginners and intermediates. Drains well after rains.

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.
