San Miguel River Class I - III: The San Miguel River winds its way through Rocky Mountains' alpine terrain near Telluride, Colorado and Trout Lake to a desert confluence with the Dolores River 80 miles north. Sandstone canyons vie with granite passages for nature at its best. Some rare riverbank plant life thrives here and as you work your way toward the Dolores and lower elevations, the flora and fauna will change seemingly around each bend. Class II and III rapids along the Upper San Miguel provide challenging kayaking and rafting. Trips varying in length from 1-5 days can be done on the San Miguel and trips of 6-12 days are available by combining the San Miguel with the Dolores.
