The Hoh River Trail quota sites — Elk Lake, Martin Creek and Glacier Meadows — plus every group (7-12 people) and stock site along the trail.
Olympic's own wilderness reservations page lists Elk Lake, Martin Creek and Glacier Meadows as quota sites on the Hoh River Trail, and makes every group site (party size 7-12) and stock site along the trail quota too. Their permits come out in the April 15 bulk release, and the page says no additional availability opens for quota areas later.
