Los Argüellos Biosphere Reserve


Have you ever visited a tourist cave? In this reserve you'll find one of the largest and most spectacular in northern Spain: the Valporquero cave. There are also a number of others such as the Llamazares and Barredo caves. You can expect to see narrow crevasses and ravines like the Vegacervera and Valdeteja gorges. What animals can you find there? Here are a couple of curious facts: Five of the 26 species of bats existing on the Iberian peninsular can be found in this area. This territory is crucial for the survival of the brown bear, an endangered species in Spain. What's on offer in the Biosphere Reserve? To explore the area you'll find a number of itineraries that you can either do on foot or by bike. Other options are climbing or canyonning. And if you want to visit the Valporquero cave, remember you can make your reservations online.
