The Numbers Full day offers the adventurer a day of constant challenging whitewater within Granite Gorge and the Numbers sections (Class IV+) of the Arkansas River. Pine Creek Rapid (V) is just the icing on the cake between these 2 sections and it is the most challenging rafting on the entire Arkansas River! This section is continuous action filled with pour-overs and steep drops. Pine Creek Rapid (V) is optional for the class IV guests. Guides will assess each crew to determine whether they are up for the challenge. Guests always have the option to bypass Pine Creek Rapid and continue their full day experience. For physically fit, experienced rafters.
