The Olympic National Park website, , unlike many of its ilk, has really good trail descriptions. The folks at the Wilderness Information Center in Port Angeles, WA, will help you plan your trip (they are also the ones who issue the permits). You might want to read a good hiking guidebook to prepare. I like the ones put out by The Mountaineers. The research will find you a hike you enjoy, rather than just one suggested by someone who doesn't know your likes and dislikes.
