we went from the rail line up through the center of the park and flew out. river travel is unavoidable and all river systems in the area were low and still falling. so check conditions and have a plan b. where it was a paddle through, now you had to line. where you could line, now you had to carry. for the people coming in behind us, they would find numerous sections that they had to portage down the riverbed (say 100-500m) to find enough water to float the boat. we made it through fine, but it would not be a pleasant experience for all. light packs and good footwear are a must. that said, we're going back in 2007.
