Confirmed from Thompson's Field Conservation 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.

wide open spaces, tons of trails, one of our dog’s favorite places on cape! unbridled joy as he runs off leash to his heart’s content. very thankful for this place to let him roam. there is a water source at the trailhead too. excellent dog spot.

★★★★★ — Juli , Apr 2019

Great place to walk the dogs. Many trails and several open fields to choose from. I love the see the dogs playing all together. Be aware that most dogs are off leash.

★★★★★ — Miguel , Jan 2023

If your dog loves other dogs this is a great place to take them for a walk as you’ll likely encounter many other dogs. Acres and acres of conservation land.

★★★★★ — Charise , Jul 2021

Excellent walk. So happy I can let my dog off leash. I've recently heard reports of broken glass on the trails, we did not experience that today.

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.
