Confirmed from Mahlon Dickerson Reservation'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.

🏞️ beautiful scenery 3 mentions

“Beautiful park with miles and miles if both easy hiking and biking trails as well as challenging mountain bike terrain.”

🌾 quiet & peaceful 3 mentions

“Beautiful quiet place for a walk at any pace”

Had a great time camping with 2 families at Mahlon Dickerson Reservation in August 2020. This review is mainly about our experience camping at the shelters (not the tents). MDR is a fairly secluded place, even if it's only 15 min from Rt. 80 in Jefferson. Pros: + secluded, private place.

Make sure you read the fine print. The RV sites do NOT allow ground fires. But that was our fault for not reading that. Beautiful campsites. I love that we arnt on top of our neighbor. Nice paths to the clean and maintained bathrooms. Nice council fire ring where you can have a fire and a large field to play on.

First time visiting - Nice RV Sites – Electric and water hookup available at each site – VERY clean bathrooms and showers (that was awesome) – Fire Wood available - Hiking trails - very helpful and friendly staff. A+++

★★★★★ — Tony , Jul 2021

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 lack of a full bathroom (there is one at the RV site about 1/4 mile away, not sure if it's open right now) was a drawback for some members of my family.”
