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

The Río Corostic serves up a full-course meal of tasty rapids. You've got short falls, high falls, long and technical, and chutes to shoot. And you'll be one of the first to savor them.

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

Flow Notes: There is a streamflow gauge downstream on the Río Tulijá, linked to below. Only a fraction of the flow here is from the Corostic, though. Below I also show historical flows at the Tulijá gauge.
