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

The Río Nacayumba is a pretty little creek out in the backwoods well to the south of Tuxtla Gutierrez bordering a protected area called the La Frailescana. The biggest challenge of the trip is making it across the terrible roads of the Villa Flores area to get there. Personally I think the run has potential as a family-friendly raft trip, but I guess it will be a while before an adventure company could make a go of it out here.

A full description is in the Mayan Whitewater: Chiapas & Belize guidebook.

Flow Notes: There is a convenient gauge downstream on the Río Nijundilo, shown below. The Nacayumba is about 85% of the Nijundilo but the gauge is not accurate. In 2012, a reading of 2100 cfs gave about 1200 cfs in the main run. Also here I include some historical data.
