Rugged Extremadura is a find for any lover of the outdoors, so bring your mountain bike (or plan on renting one), hiking boots, and binoculars. The lush Jerte Valley and the craggy peaks of the Sierra de Gredos mark Upper Extremadura's fertile landscape. South of the Jerte Valley is the historical town of Plasencia and the 15th-century Yuste Monastery. In Extremadura's central interior are the provincial
capital of Cáceres and the Monfragüe National Park, the province’s first and only federally protected park. Lower Extremadura's main towns—Mérida, Badajoz, Olivenza, and Zafra—bolstered by the sizable Portuguese population, have long exuded a Portuguese flavor.
