Best Rafting in Colorado

Best Rafting in Colorado

Some of the best rafting in the world exists among Colorado’s rivers. From easy, family-friendly trips to advanced whitewater rafting adventure, Colorado’s rivers have it all. Colorado’s rafting season runs from May through September, with the fastest and highest waters occurring earlier in the season and milder flows occurring in the later months. For more advanced rafters, the early months in the season, May and June, provide some of the most exhilarating rides, with the winter snow melt creating the most active whitewater adventures. August and September bring milder and more leisurely rides when the water flow subsides, allowing rafters to enjoy the beauty of the canyons and gorges they float through.

There are a couple dozen viable rafting rivers in Colorado that provide great adventure and fun for rafting enthusiasts. Here are five of the most popular ones that span the spectrum of excitement allowing time on the water for experienced adventure seekers and those looking for the equivalent of a nice stroll in the park.

The Arkansas River is one of the nation’s most popular rafting rivers running through some of the state’s most beautiful geologic landscapes. It cuts through central Colorado canyons and drops 5,000 feet in elevation in the first 125 miles, creating conditions for all rafting experience levels. The Browns Canyon National Monument section offers scenic, family-friendly rides. The Bighorn Sheep Canyon and Royal Gorge stretches offer much more advanced rides. Departure cities include Buena Vista, Salida, and Canyon City.

The Roaring Fork River is also split up into two sections, the upper and lower Roaring Fork, with the upper section known as “Slaughterhouse” for is extremely challenging rapids, and home to one of the state’s few commercially rafted waterfalls.
