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

Río San Pedro is one of several tributaries joining Río Almandro from the left a little before it enters Itzantún gorge (the others are Ríos Mazantic and Cuculó). Approaching the lower Almandro from Tapijulapa, you’ll drive near this river and ask, “Why not shorten my shuttle by 15 km and add on a nice class III warm-up run?” It would be sound reasoning. But Río San Pedro is interesting enough to stand as a run on its own for those who don’t want the challenges of the class IV/V passages in Itzantún.

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