This Reserve has its uniqueness in the geobiological rarities it hosts, as well as its surprising landscapes. Cabo de Gata is a volcanic relief, located on the European Mediterranean coast and with a semi-desert ecosystem. Such conditions have generated an environment of hard substratum with great internal contrasts, which houses a multitude of endemic species and where the optimisation of its very scarce water resources has led to a wide range of techniques and instruments to make water available.
