The Caído well is located on the Pacín River, a tributary of the Limia River that rises in the Serra do Laboreiro, in Portugal, where it is called Corga do Azebedo. For many kilometers this river forms the natural border between Spain and Portugal.

To get to the Caído well, we will take the OU-1212, in Entrimo, in the direction of A Feira Vella. Once there we already find the signs to the waterfall. The road reaches the river beach of the Pacín River, where we will park our vehicle to walk along a path to the waterfall, whose surroundings are equipped with a viewpoint and a wooden walkway.
