Barranco del Infierno is a nature reserve in the municipality of Adeje, in the island's southwest, whose more than 1,800 hectares (7 square miles) harbour one of Tenerife's most rugged natural landscapes. For just this reason, and for its quirks of topography, it has become a very popular hiking route. One of those quirks is the gorge which gives the reserve its name - a metres-deep cleft produced by millenia of water erosion. Other areas of the park worth visiting include the Rocks of Conde, of Imoque, and of Abinque. The vegetation here is another reason why this is one of the most beautiful spots on the island for nature-lovers.
