This is a true Quinault-to-high-country climb: 13.8 miles round-trip (6.9 miles one way) from the Irely Lake Trailhead up to the secluded Three Lakes basin. Expect about 2,900 feet of gain and a steady shift from dripping rainforest along Irely and Big creeks into cool montane fir and hemlock, then subalpine meadows and a small, quiet lake at the top. It’s beautiful, varied, and feels remote.

What to expect

The tread is primitive and infrequently maintained—think roots, mud, blowdowns, and a few brushy stretches. Below, you’ll pass creeks, small cascades, and classic Quinault giants; higher up, the forest transitions to silver fir and Alaska/yellow cedar with open meadows around the basin. A short detour off-trail reveals a local celebrity: the world’s largest Alaska cedar. The trail meets the Skyline Primitive Trail near the basin, a traditional launch for the longer Queets–Quinault Skyline traverse.

Hazards and conditions

Big Creek can be hazardous or even impassable during heavy rain or spring snowmelt. Early season can bring lingering snow in meadows and near the Skyline junction, hiding the tread and forcing careful navigation; when snow remains, the park advises expert map-and-compass skills and even ice axe/self-arrest proficiency. This is wilderness travel—expect a slower pace than the mileage suggests.

Camping and regulations

Designated backcountry campsites sit at Three Lakes, with a pit toilet and a bear wire. A wilderness permit is required for overnight stays. Campfires are prohibited. Stock are allowed for travel on the trail but not for camping at Three Lakes. If you continue along the Skyline Primitive Trail beyond the basin, bear canisters are required due to lack of suitable trees for food hangs. Treat all water from creeks and lakes before drinking.

Best time to hike

Target early July through October for lower water and mostly snow-free travel. Earlier in the season, be ready to turn around at high creeks or snow-covered sections.

Who will love it (and who won’t)

If you want solitude, old-growth grandeur, and an authentic, slightly scrappy climb to a subalpine lakes basin, this one delivers. If you prefer perfectly groomed trails, frequent signage, and easy creek crossings, pick something mellower on the Quinault instead.

Pros

  • Progression from lush rainforest to subalpine meadows in one hike
  • Detour to the world’s largest Alaska cedar
  • Designated backcountry camp with bear wire and pit toilet

Cons

  • Infrequently maintained tread with blowdowns and brush
  • Big Creek crossing can be hazardous or impassable in high water
  • Early-season snow can hide the route; navigation and snow skills needed

Parking

Park at the Irely Lake Trailhead off North Shore Road near the North Fork Campground (Lake Quinault side).

Caution

Primitive tread, potential blowdowns, and early-season snow. Big Creek may be hazardous or impassable after heavy rain or snowmelt. Carry navigation; when snow remains, expert skills and ice axe/self-arrest proficiency are recommended. No pets; campfires prohibited.
