Olympic National Park in Washington is one of the most diverse national parks. The park itself is spread out across the large Olympic peninsula in Washington, and requires a full day to just drive around. There are several different areas of the park. Close to Port Angeles, Hurricane Ridge is a sub-alpine environment similar to those at North Cascades and Rainier at 5,000 feet high. You can either take in a viewpoint or hike through the paths in the meadows. The Hoh River rain forest was a little disappointing, as it was very similar to other forested areas of the Pacific Northwest I had already been to. Although the moss-draped branches of the maples were interesting, it probably is not worth the trip if you have limited time. Rialto Beach on the Pacific Ocean has a very nice, wide, sandy beach with offshore rocks and islets. Go on a day when it is not too foggy. Beyond the car, the park offers a lot of hiking to backpackers, with trails criss-crossing the wilderness interior.
