4 Best Sights in Rain Forests, Olympic National Park

South of Forks, an 18-mile spur road links Highway 101 with this unique temperate rain forest, where spruce and hemlock trees soar to heights of more than 200 feet. Alders and big-leaf maples are so densely covered with mosses they look more like shaggy prehistoric animals than trees, and elk browse in shaded glens. Be prepared for precipitation: the region receives 140 inches or more each year.

Pick up park maps and pamphlets, permits, and activities lists in this busy, woodsy chalet, which also has a shop and exhibits on natural history. Several short interpretive trails and longer wilderness treks start from here.

This glimmering lake, 4½ miles long and 300 feet deep, is the first landmark you'll reach when driving the west-side loop of U.S. 101. The rain forest is thickest here, with moss-draped maples and alders, and towering spruce, fir, and hemlock. Enchanted Valley, high up near the Quinault River's source, is a deeply glaciated valley that's closer to the Hood Canal than to the Pacific Ocean. A scenic loop drive circles the lake and travels around a section of the Quinault River.

The National Forest Service's ranger station near the Lake Quinault Lodge has maps, campground information, and program listings.
