Morning comes cool and clear in the San Juans, and the San Miguel River is already talking—snowmelt urging the current forward, riffles hissing against red sandstone as if daring you to climb in. At Caddis Flats, a short drive down-valley from Telluride, guides clip helmets, tighten PFDs, and slide bright rafts into water as cold and clean as the peaks it just left. You step in, toes tingling, paddle poised. On this half-day run, the San Miguel wastes no time, pushing around cottonwood islands and pulling you toward quick, splashy drops that wake up the whole crew.
