The stone labyrinth of Las Tuerces has several paths and the Natural monument can be explored according to one's taste, letting oneself be guided by intuition and the indications of the itineraries. The track is a general proposal with a loop that approaches the viewpoints of the Pisuerga River to learn about the natural, geological and environmental values of the natural area. The Las Tuerces labyrinth occupies a plain of limestone rocks sculpted by water erosion on a syncline hanging in the canyon of the Pisuerga River, a territory of geological interest because it marks the meeting between the Cantabrian mountains and the lands of the moor. In the shadowy stone alleys, relict beech trees, hazelnut trees, gall oaks, rocky vegetation and thorny plants from humid environments typical of other latitudes appear, coexisting amazingly with holm oaks, junipers and shrubs from a Mediterranean environment, a forest wonder. An admirable whim of nature that is a lesson in geology and the history of the Earth in the last hundred million years in the open air.
