Description: (click here for general notes about my descriptions)

The Río Nentón is the most northwest of the Northwest. But with a good road leading to it, nice tropical forest, and fun moderate class IV rapids, it shouldn’t be overlooked by paddlers passing through the area.

A full description is in the Mayan Whitewater Guatemala guidebook.

Descent History: Nils Saubès and I ran this one in October 2014.

Flow Notes: There is an online gauge downstream in Mexico on the Río San Gregorio (Puente Concordia gauge). In 2014, 6,000 cfs on the gauge gave 1,200 cfs at Nentón, a nice flow, and above the average for the years I have historical data.

Nearby Tourist Attractions: the Cimarron sinkhole north of Nentón.
