TroutMap RiverGuides for the Colorado River cover the area from near Parshall to Kremmling, and from Pumphouse Access, just below Gore Canyon, to Dotsero. The Parshall to Kremmling area is not floatable. The other three sets of RiverGuides from Pumphouse to Dotsero cover a one- or two-day float. Two combination sets combine these three individual sets.
