One of the hidden ecological treasures of Europe is the Picos de Europa. These mountains in the North of Spain contain species of butterflies and meadow plants that are unique to the region. There are also vultures, wild boar, brown bears and mountain goats. It is an bird-watchers paradise, but do not expect it to be hot and bring the water-proofs as every time I have been there it has rained!
