Confirmed from Mary Macdonald Preserve at Horseshoe Harbor'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 11 mentions

“This had a wonderful trail across varied terrain complete with magical tree root steps and came out to the most beautiful little beach and rocky area.”

What a great find! A random trip up to the Keweenaw Peninsula, stayed the night in Copper Harbor and decided to explore the next morning before heading back south and east. We drove to the end of the road.

★★★★★ — Yolo , Sep 2025

Wow, a geological wonder with the copper harbor conglomerate and interbedded stromatolites on lake superior. What could be better? Well, how about a chance to find yooperlite or just have a stone skipping championship or a cool swim! All this and more at the end of US41 only 1991 miles from Miami.

★★★★★ — Joseph , Jul 2021

A short walk to a rock and pebble beach with few people and a beautiful view. Plan on swimming if it's hot. It doesn't make sense to have handicapped parking there, but there are 2 spots. Even the most able bodies need to watch close to navigate the rocky, root-filled trail out to the beach.

★★★★★ — Sandra , Aug 2021

A hidden gem as the saying goes. Kind of a long way 4-7 miles down dirt road to get to park. Once parked it is about a 1/3 mile trail walk, lots of tree roots but doable. Once you get to the beach, the rocks are pretty cool purples browns.

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.
