Hiking Olympic National Park By Erik Molvar Heart 'o the Hills Trail This 2-milc trail leads eastward from Loop E of the Heart 'o the Hills Campground. It offers no mountain views, but does travel through some of the most stately old growth forest on the Olympic Peninsula. This ancient woodland is made up of silver fir, red cedar, and Douglas fir, with some of the largest trees exceeding 8 feet in diameter. Old trees often die from the top down, and the broken-topped giants provide the unique nesting habitat for the northern spotted owl, one of the most celebrated and controversial of the endangered species. The trail stays fairly level for the majority of its length, where numerous small rills are choked with the giant leaves of devils club and skunk cabbage. As the widely spaced giants give way to a younger stand of hemlock and Douglas fir, the path descends steadily into a narrow creek valley. The trail ends rather ignominiously at the Park boundary, where a clearcut has been pushed right up the edge of the Park, swallowing up the trail in the process.
