About this water

The Alberche is a granite freestone rising on the Sierra de Gredos and flowing south out of Ávila. This covers the upper mountain stretch near the Gredos headwaters, not the river's lower reaches further downstream. Clear, cold headwaters, pocket water, and granite pool-and-run structure support wild browns and technical small-river tactics.
