Catalonia is a must-visit destination for nature lovers. At the Catalan natural parks you will find mammals, reptiles, amphibians, insects and lots more fauna and flora to see and learn about. Catalonia has 18 natural parks, including Catalonia's only National Park, the Aigüestortes and Sant Maurici Lake National Park, with its wealth of flora and fauna, nearly 200 lakes and impressive crags.
Each of the country's natural parks has its own special charm.

If what you like is birds, you have an infinite number of options to study or just watch them.
You need go no further as three of Europe's most important habitats for bird-watching are located right here, in Catalonia, and they are equipped with everything you need to watch birds: viewpoints, hides... There is the Ebro Delta, the Llobregat Delta and marshes of the Empordà. Since they are on the coast, they are all stopover points for birds on migration and therefore a great many species can be seen.
If you like bird watching but what interests you is studying birdlife in depth, you should be aware that all three parks regularly organize activities devoted to dissemination, like the World Bird Day.
