Fodor's Expert Review Puerto de Tornavacas

There's no more striking introduction to Extremadura than the Puerto de Tornavacas—literally, the point "where the cows turn back." Part of the N110 road northeast of Plasencia, the pass marks the border between Extremadura and the stark plateau of Castile. Its elevation of 4,183 feet affords a breathtaking view of the valley formed by the fast-flowing Jerte River. The lower slopes are covered with a dense mantle of ash, chestnut, and cherry trees, whose richness contrasts with the granite cliffs of Castile's Sierra de Gredos, blanketed in garnacha grapevines. But cherries, of course, are the principal crop. Camping is popular in this area (contact the tourist office for more details), and even the most experienced hikers can find some challenging trails.
