From the 7,980-foot summit of Mount Olympus, the Pacific Ocean shimmers in the distance, less than 33 miles west. Between the highest peak in the Olympic Mountain range and sea is a jumble of rugged peaks, whose shoulders are decorated with meadows and lakes. Geology, climate, isolation, history and sheer size mean this nearly one million-acre park protects relatively intact ecosystems, making it a priceless living laboratory and a home for plants and animals large and small. Leashed pets are allowed on Rialto Beach, the Kalaloch beaches, on Peabody Creek Trail, and in developed areas, such as picnic areas, parking lots, and along gravel and paved roads. Pets are not allowed in the buildings, in wilderness areas, or in boats on park rivers. Leashes must be no longer than six feet.
