Here's your chance to travel down one of the world's great rivers from first trickle to final delta. See the West's natural wonders while tracing the Colorado River and its major tributary, the Green River, as they flow through several habitats and millions of years of geological history. En route to the sea, the rivers bend through national parks, monuments, wildlife refuges, and recreation areas, nourishing wildlife and outdoors folk alike. You'll visit river towns and some of the best fishing holes and recreation areas, and learn about glaciers, dinosaurs, miners, and mountain men along the way. Ride along (staying dry all the way) through the vast Colorado River Basin and of course through the unforgettable colors and vistas of the grandest canyon on earth.
