Starlight reserves Clear skies, no light pollution, and the facilities you need to enjoy an unusual evening discovering the constellations. This is the 100% sustainable holiday experience on offer in some of the world’s best astrotourism locations. You can find more information in this article Cattle migration paths These are the routes used for centuries by Spanish shepherds and cattle herders moving their herds between their summer and winter pastures - known as Trashumancia. Some of these routes are now marked and adapted for hiking and cycling, and run through beautiful scenery. For example, you can follow them through the Sierra de Gredos (Ávila) or the Trashumancia route of the Catalan Pyrenees (Lleida).

Former railway tracks for walking in nature Known as Greenways or Vías Verdes, these are abandoned railway lines that have been adapted for hiking and cycling in natural surroundings. Spain has a total of more than 3,200 kilometres of Greenways. These paths are a good example of restoring the environment, and on some you can see rare animals, such as bears. This is the case of the Senda del Oso (Bear Path) in Asturias, where the bear Paca lives in the hills. He was rescued as a cub and now lives on a nearby mountain, and every day he comes down to be fed (around 12 noon) in a part of the path near Proaza.

Visit unique, ancient olive trees Virgin olive oil is an ancient agricultural tradition in Spain. As well as tasting the oil, you can visit numerous almazaras (olive oil mills) and vast olive groves. You can even discover some well-known unique olive trees and marvel at their size (you need more than four people to encircle their trunk). For example, in Jaén (Andalusia) there are guided tours to see hundred-year-old olive trees in places like Martos; in Catalonia they are organised in Ulldecona (Tarragona), and the Valencia region boasts thousand-year-old olive trees in Canet Lo Roig (Castellón).

Spain also has more biosphere reserves than any other country in the world. In total, it has 53 spaces with outstanding biodiversity. You can find excellent examples of the integration of sustainable tourism on the islands of Lanzarote, El Hierro, La Gomera and Fuerteventura, top-class tourist destinations that are also Biosphere Reserves. In fact, El Hierro is the first island to be self-sufficient in renewable energy.
