National Geographic Colorado River Fishing & River Recreation Map Guide: Headwaters to Kremmling

From the publisher:Traveling approximately 76 miles and dropping just shy of 3,000 feet in elevation, the section of the upper Colorado River represented in this map—from its headwaters to Kremmling—winds through diverse landscapes, passes near the towns of Granby, Hot Sulphur Springs, Kremmling, and Parshall, supporting a variety of ecosystems as it morphs into a powerful and mighty waterway known for prolific insect life; brown, rainbow, and brook trout (and the occasional cutthroat); wildlife viewing opportunities; and superb cultural and historical features.

Offering copious chances for recreation, including camping; stellar angling; and unguided rafting, kayaking, and stand-up paddle boarding on the Fraser River between Tabernash and Granby and through Byers Canyon (a classic Class IV run on the Colorado River), this waterway and its tributaries—which are the lifeblood of the basin—draw nature lovers, explorers, and anglers from across the globe seeking to experience the Colorado's world-class fly-fishing, spectacular scenery, and remarkable adventure opportunities.
