What to Expect

Step onto the boardwalk and within seconds you'll understand why this place feels like another planet. The Hall of Mosses is a short loop through the Hoh Rain Forest — one of the few temperate rainforests in the lower 48 — where every surface is draped in club moss, licorice fern, and spikemoss so thick the trees look like they're wearing fur coats. The trail is almost entirely flat, winding beneath massive Sitka spruces and bigleaf maples whose branches sag under curtains of moss that hang like chandeliers. The signature moment comes at the moss hall itself, where the canopy closes in and the light filters through green so deep it feels underwater. The whole thing takes about thirty minutes, which means every minute is dense with something worth stopping for. This is the trail for anyone who wants to feel genuinely transported without breaking a sweat.

Safety Advisory

The boardwalk sections get slick when wet, which is most of the time. Wear shoes with decent tread — flip-flops and smooth-soled boots are a recipe for a bruised tailbone.

Roosevelt elk wander through this area regularly and can be surprisingly aggressive during rut season in fall. Keep at least fifty yards of distance and never position yourself between a cow and her calf.

Pro Tips

Trail Tip

Arrive before 9 AM or after 4 PM — the Hoh Rain Forest parking lot fills completely by mid-morning in summer, and the ranger station will turn you away at the entrance road once it's full. There's no overflow lot and no shoulder parking allowed.

Trail Tip

Bring a rain jacket no matter what the forecast says. The Hoh gets twelve feet of rain a year, and showers materialize out of nowhere. Overcast days actually produce the best conditions — the moss practically glows without direct sunlight washing it out.

Trail Tip

The most photographed spot is the moss archway about halfway through the loop where maple branches form a tunnel draped in hanging moss. Shoot it with a wide angle from low to the boardwalk to get the full cathedral effect, and bump your ISO — it's darker than you'd expect even midday.
