Extremadura, on the western border of Spain with Portugal, is an important area for wildlife and walking. There is a major reserve at Monfrague, which was designated a National Park in 2007, in addition to the Tagus River Natural Park. Monfrague is an outstanding bird watching area, especially for raptors such as the Eurasian Black Vulture, Griffon Vulture, and the Spanish Imperial and Golden Eagles. With a Mediterranean climate influenced in the north where it is continental, and to the west where the influence of the Atlantic make it milder, this is a year-round destination for dedicated walkers.
