Most people drive the CV-70 as far as Guadalest and turn back. This guide takes you the whole way: out of Benidorm and up through La Nucía and Polop, into the Guadalest valley with its turquoise reservoir, over the mountains past Confrides, and down the far side into Alcoi. You get every stop worth making in the order you reach it, where to leave the car, and the places to slow down rather than drive past.
