Olympic National Park is one of the largest and most diverse national parks in the U.S. Just a three-hour drive west of Seattle, Washington, Olympic National Park is home to the largest temperate rainforest in North America, rugged beaches and glacier covered valleys high in the Olympic Mountain Range. Greg shows you how the park's three main zones are different from each other by venturing into the Hoh Rainforest, walking the pristine coastline at Ruby Beach and climbing the snow covered peaks of the Olympic Mountains.
