Confirmed from Thompson Park: Main Entrance's own listing, the park or land manager's website, and runner reviews.

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.
