Confirmed from Thanksgiving Forest 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.

“In Winter is a perfect quick ski until the hikes and dog walkers wreck the tracks.”

We love the loop trail and the connection to Great Brook. In Winter is a perfect quick ski until the hikes and dog walkers wreck the tracks. When tracks are laid, the big loop takes about 30 minutes. Note, in Winter you need to buy a ski pad at Great Brook if you are going over the creek to use their trails!

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.
