We have not been able to confirm the surface, distance or shape of Alder Trail 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.

What runners say about Alder Trail

Pulled from public reviews of this trail (6 of them) — the things people bring up again and again, in their own words. Nothing here is written by us.

Sometimes hard to follow, look for paint marks on trees if you lose the path. Connects to the Costanti Lane trail which is much clearer, and from there you can hike up into the beautiful Lookout Mountain forest preserve.

★★★★★ — Harold , Nov 2020

Pleasant area to hike. In the rainy season there’s lots of running water near the bottom. Some parts will be swampy. The Lower section connects to an abandoned road about 1 mile in. From there the footing is better. Not sure how far the trail goes. I spent an hour up and 45 minutes back down. Went 3.3 miles in all.

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.
