The boardwalk to Sandpoint traverses dense coastal forest. Mild temperatures and abundant rain can nourish a dense tangle of forest along Olympic's coast. Head high shrubs crowd under a canopy of Sitka spruce, western hemlock, and western redcedar. Ferns and mosses form a spongy carpet below. In a few areas the forest gives way to wet coastal prairies with acid-loving bog plants like wild cranberry, crowberry, bog laurel, Labrador-tea, sundew and sphagnum.
