The Senda de las Gariñas is a circular path 6.5 km long. The route crosses part of the forest mass known as the Gariñas forest and reaches the Puentes Viejas reservoir, where we find the riverside landscape. The forest is made up mostly of resin pine, although as we approach the banks of the reservoir we also find ash trees and Montpellier maples.
