Via Verde de la Sierra (90% gravel)

The Via Verde de la Sierra is a beautiful green route in Andalusia that starts in Puerto Serrano and ends in Olvera. This 36-kilometre route follows an old railway line that was built in the early 20th century between Jerez de la Frontera and Almargen. The route offers a unique combination of beautiful nature and historical sights, including the impressive Sierra de Cádiz and a large colony of Griffon Vultures. The route is ideal for both walking and cycling and passes through several tunnels and viaducts, making it a unique experience. Along the way you will pass through smaller villages and peaceful landscapes, making it perfect for a relaxing adventure in nature.
