Walkers ravine in Municipal of Adeje. The gorge boasts one of the few permanent streams in the south of island. You do not have to be a keen hiker to transverse this gully. Walk takes approx. 70 mins, each way. Bar/Restaurant at entrance to Barranco. Wear tough shoes. In the South, Barranco del Infierno, also called Hell’s Gorge, is a huge ravine where cacti and rocks suddenly give way to amazingly abundant foliage and a waterfall bang in the middle of volcano country! The Esperanza Forest is a lovely alpine forest with gleaming pines shrouded in mist.
