From Cazalla train station to Cerro de Hierro
The best part of this rail trail is particularly interesting because almost anybody can ride it. the route is perfectly paved for the great majority of its length. It commences near the train station of Cazalla-Constantina and continues alongside the Huéznar River to its source in San Nicolas del Puerto, which is a curious place where the cystal clear water bubbles up from the ground. San Nicolas also has a lovely fluvial beach for a refreshing swim in hot weather.
From San Nicolas the trail continues to Cerro del Hierro, an extraordinary place to explore with strange karst landforms and mining histroy and relics, it was exploited by the Scottish in the 19th and 20th centuries.
The rail trail itself is a very gradual climb and passes through Mediterranean Woods, over bridges, by holm oak meadows, through a tunnel and the lush and verdant growth around the river. A pleasure for the senses!
