The medieval city of Guadalest is Spain's third most visited tourist attraction. In the valley below is a lake that it is possible to walk around. Guadalest is worth a visit. It is one of the best-preserved medieval cities in Spain. It is a fortress town made on top of a cliff in a beautiful mountain landscape. The cliff provides natural protection, but also limits the development. On the southwest side of the water there is a path along the water's edge. Start the tour here.
