The Cueva del Puerto or Cueva de el Puerto (Cave of the Door) is famous for various speleothems. One chamber is called Sala Gaudí because the stalagmites resemble the buildings of the famous spanish architect. Highlights are great numbers of helictites. What is not really appreciated by visitors or guides is the hypogenic origin of the cave, which is currently being studied as part of a research project. Hypogenic means, that the water which actually formed the cave was not rain water from above, but thermal water from below. The result is a variety of unusual solution forms on the walls and ceiling of the cave. And while the guide tells the names of formations use the time to enjoy the aesthetic value of those forms.

The numerous hypogenic morphologies in Cueva del Puerto make it a reference for the study of hydrothermal networks. However, the majority of caves in Murcia was formed by these processes. The landscape in the Region of Murcia lacks typical karst features which are known from many other karst regions. There are no sinks, dolines, poljes or karst lakes. Nevertheless, major cave systems can be found through small entrances in unexpected places.

The hydrothermal origin of the cave is linked to the Calasparra syncline aquifer. The Calasparra syncline occupies an area of 330 km² and is about 500 m deep. The aquifer fills the sedimentary rocks of the syncline and is today drained by the Rio Segura. The limestones reach the surface in the northern and southern hills along the valley, which runs east to west. The basic idea is, that limestone was filled with the water and the caves dissolved by the thermal water from below. Then the ongoing uplift together with the erosion in the valley lowered the water level and the caves became dry.

The cave is located at the end of a paved road, which was obviously built to access the cave. It is located in the top of a hill, the entrance is on one side of the hill, the exit on the other side. The 400 m walk back across the hill offers a great view on the Rio Segura valley.

The cave offers cave trekking tours which descend to the Gran Diaclasa chamber, which is the deepest point of the cave. The tours are organized by Qalat Naturaleza y Aventura. Participants must be 16 and physically fit. They are equipped with a full caving gear by the operator. Bring clothes to change and a towel.

The Sierra del Puerto is located at the foot of the Betic Mountain Range. It is made up of limestones and dolomites from the Upper Cretaceous (Cenomanian-Maastrichtian). A basal dolomitic complex and an upper limestone formation are karstified. The Betic mountain range was uplifted during the Alpine orogeny, and also the Sierra del Puerto. This was the beginning of the karstification.
