Charco (poza de río)
A natural freshwater pool in a mountain river, often with a waterfall or a rock to jump from. They are the weekend plan for many locals and there are dozens across the mountain range. Water levels rise fast when it rains upstream, so nobody swims when the river runs muddy or strong.
Example
A charco with clear still water is safe, and the same charco running brown after a storm is not.

Frequently asked questions
Are they safe for swimming?
With the river low and clear, yes, with normal freshwater caution. After recent mountain rain, no.
Is there a lifeguard?
Almost never. They are unsupervised natural pools, so your own judgment and the state of the river decide.
