Fly Fishing the Crystal River

Colorado's last major dam-free freestone river in the Roaring Fork Valley, the Crystal runs 35 miles through White River National Forest from its headwaters above Marble to its confluence with the Roaring Fork at Carbondale, holding wild rainbows and browns to 18 inches alongside a robust whitefish population in clear, boulder-studded water.
