In March of 2008, we backpacked the 62km length of the Paria canyon. Although wet and somewhat cold so early in the season (we waded in the river proper for at least half the hike, and encountered 1 freak snowstorm on the second day), the scenery was spectacular and well worth the effort. What's more, the snow seemed to have scared a good many hikers away, and we saw only 3 others on the trail in the 5 days of hiking!
