A main town is accessible by the national roadway E.N. 231, that connects directly to the region of the Serra da Estrela by way of E.N.338 (which was completed in 2006), or through the E.N.339, a 9.2 kilometre access that transits some of the main elevations (960 metres near Portela do Arão or Portela de Loriga, and 1650 metres around the Lagoa Comprida). The region is carved by U-shaped glacial valleys, modelled by the movement of ancient glaciers. The main valley, "Vale de Loriga" was carved by longitudinal abrasion that also created rounded pockets, where the glacial resistance was minor. Starting at an altitude of 1991 metres along the Serra da Estrela the valley descends abruptly until 290 metres above sea level (around Vide), passing villages such as Cabeça, Casal do Rei and Muro. The central town, Loriga, is seven kilometres from Torre (the highest point), but the parish is sculpted by cliffs, alluvial plains and glacial lakes deposited during millennia of glacial erosion, and surrounded by rare ancient forest that surrounded the lateral flanks of these glaciers. Textiles are the principal local export; Loriga was a hub the textile and wool industries during the mid-19th century, in addition to being subsistence agriculture responsible for the cultivation of corn. The Loriguense economy is based on metallurgical industries, bread-making, commercial shops, restaurants and agricultural support services. While that textile industry has since dissipated, the town began to attract a tourist trade due to its proximity to the Serra da Estrela and Vodafone Ski Resort (the only ski center in Portugal), which was constructed totally the parish limits.
