The headwaters of the Rio Grande is a very family-friendly stretch of river at it flows past South Fork. The solitude and breathtaking scenery are unparalleled in the state of Colorado and plenty of relaxing stretches of water exist. For the more adventurous, class II-III rapids are available too! May and June are the best months for whitewater action, but no matter the time of season, the river has its own character and each trip is as rewarding as the first. A local rafting company and outdoor shops offer river trips, gear, and information.
