An early morning drive or walk in the rainforests might bring a sighting of Roosevelt elk. Five species of salmon migrate up the park's rivers to spawn. Most easily viewed are coho salmon jumping the Salmon Cascades on the Soleduck River in late September to early October. Bald eagles and peregrine falcons nest along the coast, as do tufted puffins, murres, and other sea birds. The spring hawk migration funneling through Neah Bay north of the park is another impressive sight.
Tide pools harbor sea stars, urchins, and many other colorful marine invertebrates.
Offshore, gray whales migrate by in spring and fall, a stirring event all along the West Coast.
