The Sierra de Ancares Natural Area is a stunning mountain range straddling the border between Galicia and Castile and León in northwestern Spain, celebrated for its rugged landscapes, rich biodiversity, and traditional rural heritage.
The Sierra de Ancares Natural Area is part of the greater Ancares mountain system that forms a natural boundary between the provinces of León and Lugo in northwestern Spain. This protected area is distinguished by its impressive geological formations, encompassing steep slopes, deep valleys, and striking peaks such as Pico Miravalles and Mustallar, which rise above 1,900 meters. The region's diverse ecology includes ancient oak and chestnut forests, heathlands, and alpine meadows that support a variety of endemic and rare plant species. Wildlife is abundant, featuring species such as the Cantabrian brown bear, Iberian wolf, roe deer, wild boar, and an important population of birds of prey including golden eagles and vultures.
Historically, the Sierra de Ancares is renowned for its well-preserved traditional villages and unique 'pallozas'—circular stone dwellings with conical thatched roofs that date back to Celtic times. This cultural landscape highlights centuries of rural life and pastoralism adapted to the harsh mountainous environment. Outdoor enthusiasts visiting the area will find excellent opportunities for hiking, wildlife watching, mountain biking, and photography, in a setting that remains largely undeveloped and serene. Popular routes traverse ancient footpaths connecting picturesque villages, remote highland pastures, and panoramic viewpoints.
The natural area's appeal lies in its blend of natural beauty, cultural heritage, and tranquility. Visitors come to experience unspoiled nature alongside ancient human traditions, making the Sierra de Ancares an exceptional destination for sustainable tourism and environmental appreciation.
