Sierra Salvada Natural Area is a striking mountainous region renowned for its rugged karst landscapes, abundant biodiversity, and exceptional opportunities for hiking, climbing, and nature exploration in northern Spain.
Sierra Salvada is a prominent mountain range located along the border between the Basque provinces of Álava and Burgos in northern Spain. Characterized by dramatic limestone cliffs, deep ravines, and extensive karst formations such as caves and sinkholes, the region is an important natural habitat for a variety of flora and fauna. The area boasts Mediterranean and Atlantic influences, resulting in a varied ecosystem where beech and oak forests intermingle with Mediterranean shrublands. Sierra Salvada is historically significant, with remnants of ancient shepherding and mining activities reflecting human activity across centuries. Outdoor enthusiasts are drawn to its network of hiking trails that navigate through scenic gorges, summits with panoramic views, and unique geological features. Notable landmarks include the iconic Salto del Nervión, Spain’s tallest waterfall, which dramatically plunges over 222 meters from the Sierra Salvada cliffs. The range is also a premier destination for rock climbing due to its steep limestone walls and diverse routes. Birdwatchers appreciate the chance to spot vultures, eagles, and other raptors that nest in the cliffs. The area's remote character and natural beauty appeal to those seeking peaceful wilderness escapes combined with rich natural heritage and cultural traditions.
