I was on a solo California North Coast trip recently and had a chance to spend a full day in Redwood NP. What a beautiful place! I did three shorter hikes and loved each one. Because this park doesn't get near as many tourists as some of the more famous (and more accessible) national parks, you can go on a hike by yourself or with a loved one and not see too many people. The majesty of the redwoods is like a spiritual experience. I put up a web album if you'd like to see photos of Redwood NP and surrounding parks further south, as well. They're at Picasaweb.google.com/mjneenan and the RNP photos are # 127-142.
