Confirmed from Greenbrier State Park'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.

“Nature & Trails: The hiking trails are well-marked and suitable for all ages.”

Nice clean park but there always tons of kids there so don't expect much beach time if you're going for an adult only day trip during the spring/summer. The trails are decent though which make up for how busy it gets and the lake is beautiful to just sit and look at.

★★★★☆ — Miss , Jun 2021

Great campground pet friendly. It was only $35.00 for a site with power. The dump station is near the main entrance, which is easy to locate. Campground has lots of hills, some really steep. The lake was cold and amazing. My family and I had a great time at the lake and walking the trails.

★★★★☆ — Jeremy , Jun 2025

Large, pleasant and relaxing park. I really liked the peacefulness of the area, the beach by the lake, the mini hiking in the forest, the walking tour of the lake, the beach and the bird calls as the only surrounding noise in some spots. I’d have loved to encounter a black bear 🤪

★★★★★ — Ronnie , May 2024

We made reservations for the weekend on their website, and paid $5 pp at the time of reservation. We got an email confirmation with a QR that we showed to the ranger. We for there around 10am parking wasnt difficult there were plenty of spots. None were that far from the park.

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.
