The northeast of the province of Segovia is a changing landscape fragmented by the Riaza River, whose flow defines three well-differentiated areas.
From the southeast it appears as a soft relief, before entering a calcareous canyon that reaches one hundred and fifty meters deep and almost three hundred meters wide, finally becoming a fertile valley.
In line with this uniqueness, the vegetation of the Hoces del Río Riaza Natural Park is very varied, with masses of trees adapted to the harsh conditions of the continental climate such as junipers, holm oaks or gall oaks in contrast to the riverside forests that populate the bottom of the valley.
The animal world also plays a leading role in this protected area, as the rocky and limestone cliffs allow the settlement of important colonies of birds, mainly griffon vultures, while the areas of backwaters are the ideal habitat for a multitude of aquatic species.
In the final stretch of the Natural Park, coinciding with the pleasant valley, lies the town of Montejo de la Vega de la Serrezuela, between whose streets and on the banks of the river the Casa del Parque sits. Upon accessing the interior, all kinds of information is provided about the different routes that the environment allows, both from a natural and cultural point of view. An interesting audiovisual presents all the values of the other ecosystems that make up the Network of Natural Spaces of Castile and León.
The informative center offers complete information on the geomorphological characteristics of the environment, the environmental conditions and the flora and fauna through an excellent sequence of explanatory panels, while the Tunnel of Sounds has an approach to traditional values Of the territory.
It is inevitable to look up at the roof of the building and contemplate the life-size representations of the Park's birds as a preamble to the knowledge imparted about their morphology. In addition, a camera that can be operated from the Casa del Parque allows you to admire the activity of a griffon vulture nest in real time.
The nearby Linares reservoir marked the life of a part of the population and it was the inhabitants of the submerged town of Linares del Arroyo who have left a testimony of incalculable value, accessible in the Rincón de la Memoria audiovisual. This experience is completed with a collection of photographs that tell the values of the towns that make up the Natural Park.
