Hoh Rain Forest: Under the Moss“Up ahead is the Hoh Rain Forest visitor area, where I'd give most of your time to the trees. The Hall of Mosses loop takes you beneath huge conifers and bigleaf maples hung with moss.”

Trail guide
This out-and-back starts at Hoh River Trailhead, follows the Hoh River Trail to the Hoh Lake junction, climbs to the lake, and returns the same way. Hoh Lake is listed 14.7 miles from the Hoh trailhead, so plan for 29.4 miles round trip. The lake is the turnaround for this itinerary; the named trail continues beyond it toward Bogachiel Peak and the High Divide. Allow about 15 hours for the full hike, or consider an overnight with the required wilderness permit.
The first roughly 10 miles follow the Hoh River through old-growth rainforest. Expect moss-covered trees, nurse logs, and river views, with 5-Mile Island and Happy 4 among the landmarks. Olympus Guard Station is a little over nine miles from the trailhead. This approach is much gentler than the climb ahead, but its distance makes the return trip substantial before you even reach the lake.
At the Hoh River junction, turn onto the Hoh Lake Trail. The route climbs steeply for about 4.7 miles to the basin, gaining roughly 3,500 to 3,800 feet on a series of switchbacks. It leaves the valley and crosses the sparse-canopy footprint of the 1978 Hoh Fire, with little shade and no water along the climb until C.B. Flats. The exposed grade makes heat, rain, and snow more consequential than on the lower river trail.
Hoh Lake sits in a rocky subalpine basin. In season, avalanche lilies and other alpine flowers brighten the meadows, and the surrounding ridges open toward Olympic's interior mountains. Elk and bears are often seen in summer and early fall, though sightings are never assured. The High Divide trail continues beyond the lake; this route turns around at the basin rather than making that longer continuation.
The best season is generally mid-July through September, but snow can cover high sections in any season. Travel over snow requires an ice axe and self-arrest skills, and map-and-compass navigation may be needed. Treat water before drinking. Overnight hikers need a wilderness permit and must use designated sites; the lake has a composting toilet, and the C.B. Flats group site is about half a mile south. Follow current bear-canister rules and do not build campfires. Check current trail conditions before setting out because recent reports describe a washout and rough reroute above the Hoh River junction.
