This full-day river trip traverses 16 miles of wilderness gorge, encountering demanding rapids guaranteed to get you wet. This is our most exciting whitewater river trip and is NOT for the timid. Participants must be mentally and physically prepared to paddle in earnest and assist in their own rescue in the event of a "swim" or flip (Class 4/Difficult, Class 5/Very Difficult, in high water). The Box season usually begins in March, with the highest flows typically occurring in May and June but with the changes in the climate of Northern New Mexico it is near impossible to predict. Minimum age is 12.
