Confirmed from Mad River Beach County 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.

🏞️ beautiful scenery 8 mentions

“Clean sand feel (I have texture issues with sand) beautiful views, long stretch of beach as far as the eye can see!”

🌾 quiet & peaceful 4 mentions

“Kinda hippy central so we went and there were a ton of people making beach bonfires till late night but it was quiet and fun”

The long beach stretches south of the mouth of the Mad River. The surf area tends to be slightly sloped but deep, long, wide, with frequently breaking waves. Extensive dunes back the beach. Although it's a 3 mile walk from the parking lot to the River mouth, it's a 3 minute walk to the Mad River at the boat launch.

★★★★★ — Gene , Aug 2022

Great trails along lupines, blackberries in the bushes, Mad River on one side, ocean beach on the other. Fishing spots at the River. Sand dollars at the beach and Godwits. Nice spots for picnic, frisbee, and some deep River pools.

★★★★★ — Cyril , Apr 2021

I had a wonderful time. Great for all ages. My puppies had a blast running around on the beach. Highly recommend this beautiful beach.

★★★★★ — Susan , Dec 2021

There is a nice long walk for taking dogs on along the mad river to the mouth and then back along the beach. A favorite place for bonfires in the summer it does seem to be more windy than other local beaches, so dress accordingly.

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.
