Confirmed from Hidden Valley Preserve'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.

So there is a large parking area for this trail. There will be 2 bridges along the way that u can cross. There are also many trails u can choose from here and some are listed on the all trails app. We hiked over to see the quartz mine cave and it's such a beautiful area to check out.

Absolutely love this location. The Henry David Thoreau hanging bridge is pretty impressive and the perfect subject for fall foliage photography. The parking area is super close to the bridge, so you don't have to hike miles to see it.

★★★★★ — Jena , Oct 2023

Square Orange and white trail around the river across the two bridges. 1.7 miles mostly flat with some excellent views of the river and falling streams. Farthest bridge has three flights of stairs from the river to trail.

★★★★★ — Dan , Jul 2023

Another great nature preserve in CT. A good trail system. Lots of variety for return visitors. We hiked white circle trail to yellow circle trail loop. Its 1.5 miles and easy. Trail was wide and cultivated. You cross 2 bridges including the newer Henry Thoreau suspension bridge.

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.
