Confirmed from Old Calf Pasture'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 Old Calf Pasture

Pulled from public reviews of this trail (18 of them) — the things people bring up again and again, in their own words. Nothing here is written by us.

Sunday afternoon hike (December 2025) at Old Calf Pasture (Concord, MA). I parked on the shoulder of Lowell Road, walked the yellow trail to the Planning and Land Management yard, then yellow to the red, and back on the yellow. (Yes, this follows my recent hikes of the old Reformatory Branch rail bed.

★★★★☆ — David , Dec 2025

Nice hiking area, but also lots of ticks so protect yourself accordingly. Cartop launch ramp is good and you can drive to it. The issue is that you have to park on road. It's very busy and car speed by all day long so you must be hyper vigilant so as not to get hit.

★★★★☆ — Stephen , Jun 2025

A beautiful and peaceful place where you can just walk and sit for a while or take your boat or canoe down the river for a while-

★★★★★ — Kathleen , Oct 2017
