Castilla y León is a region of contrasts, and the region's environmental richness, diversity and quality mean that its landscape of mountains, valleys, lakes, plains, canyons and gorges comprises one of the most important geographical spaces of the Peninsula and one of the regions of greatest biodiversity in the whole of Europe.

We are talking, therefore, about land of high ecological value, where endangered vegetable and animal species offer a beautiful spectacle to the tourist. These Natural Spaces form the ideal place to practice sporting activities or hiking.
