Andalucia spans approximately 87,000 square kilometres across southern Spain, encompassing eight provinces: Almería, Cádiz, Córdoba, Granada, Huelva, Jaén, Málaga, and Seville. You'll find dramatic mountain ranges in the Sierra Nevada (home to mainland Spain's highest peak, Mulhacén, at 3,479 metres), rolling olive grove landscapes that stretch to the horizon, pristine Mediterranean coastline, and ancient trails connecting hilltop villages.
The region's walking infrastructure has developed significantly over recent decades. Waymarked routes now include sections of long-distance GR (Gran Recorrido) trails, local PR (Pequeño Recorrido) paths, and unmarked traditional routes that locals have used for generations. Natural parks protect much of the best walking terrain, including the Sierra de Grazalema (Spain's first natural park, designated in 1984), Cabo de Gata-Níjar Natural Park along the coast, and the Sierra Nevada National Park.
Climate plays a crucial role in planning your walks. The transitional zones, particularly the Alpujarras valleys on the southern slopes of the Sierra Nevada, benefit from microclimates that create near-perfect walking conditions for much of the year. Understanding these variations helps you choose the right time and location for your abilities and preferences.
