Natural área riding We’ll enjoy two natural parks, Los Alcornocales Natural Park, which houses the biggest, most continuous and best cared of mass of cork oaks. Its botanical and mycological richness justly earns Los Alcornocales its fame as the last European forest. The second Natural Park will be the strait of Gibraltar, where hundreds of millions of birds cross the strait every year in their migratory voyage between Europe and Africa, making it not only one of the most prominent destinations for bird watching, but one of the most ecologically diverse places in Europe too.
