Olympic in May: what the park service says
Spring at Olympic's Hurricane Ridge means wildflowers in the subalpine meadows and blacktail deer grazing among them, the park service says. The road to the ridge can still close at short notice for weather, and from October through May some of the park's roads, campgrounds and facilities are closed or keep shorter hours. The nearest campground, Heart O' the Hills, is open all year, 12 miles below the ridge and 5 miles south of Port Angeles.
