Confirmed from Proving Grounds Recreation Area'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 Proving Grounds Recreation Area

Pulled from public reviews of this trail (36 of them) — the things people bring up again and again, in their own words. Nothing here is written by us.

This place has some nice bike trails, one relatively flat and mild for beginners, and one has large jumps for the experts. Some in between. Nice pavillion, charcoal grill, and bathroom. New to mountain biking i am, and this place is very fun. Views of the Mississippi from the top.

★★★★★ — Jack , May 2020

Excellent walking and mountain bike trail, TMBR is a local mountain bike organization that takes excellent care of this park and is constantly building new trails and cool freatures

★★★★★ — Trent , Apr 2021

Awsome place the only down side is you go up a big hill too get too the trails

★★★★★ — Chris , Oct 2020

I love what they've done with the trails, looks great for mountain biking. I prefer basic hiking, so if you plan on walking, be extra mindful and watch for trails that are for bikes ONLY, as there are a few that way. Great as a new nature trail in the area though.

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.
