The Cueva del Viento - Largest lava tube in the European Union


The Cueva del Viento-Sobrado underground complex is the largest lava tube in the European Union. It was created by lava flows from Pico Viejo, next to Mt. Teide. 


A visit to Cueva del Viento gives you an insight into the role of lava flows in a volcanic eruption, and offers you the chance to see the whimsical forms sculpted by the lava in the bowels of the earth. Is a fine example of the complexity of geology.


There are three different passage levels in the more than 17 kilometres of tubes, together with beautiful geo-morphological phenomenon like chasms, terraces and other lava formations.


Geological and biological importance
The Cueva del Viento (Cave of the Wind) is a volcanic cavity located in the district of Icod de los Vinos bearing the same name. Formed 27,000 years ago in basaltic lavas from the Pico Viejo volcano during its first eruptive phase, it is located in the foothills of Mount Teide.


This tube is the fourth longest in the world (18 kilometres) and is a true labyrinthine network of underground passages, with many unexplored ramifications, which will permit the future expansion of its length as exploration continues. Apart from its size, the Cueva del Viento is noted for its unique geomorphology. Its network of galleries consists of three superimposed levels, a phenomenon that has not been noted anywhere else in the world. Its name is due to the significant flows of air that occur in its interior.


Biologically the greatest relevance of this tube lies in its subterranean fauna which provides a constant source of new findings. The cave has a total of 190 known species. Of these, forty-eight are troglobites, animals that can live only in the subsurface environment. Among these species doomed to live in the dark, fifteen are new to science such as the eyeless cockroach Loboptera subterránea or the ground beetles or carabids Wolltinerfia martini and Woltinerfia tenerifae.


From a geomorphological perspective, the Cueva del Viento features a wide variety of structures such as lava stalactites, lava cascades, side terraces and lava lakes among others, as well as exogenous concretions of different composition (calcium carbonate, cristobalite, and other silica compounds).


Inside are also lots of vertebrate fossils of extinct animals like the giant rat and the giant lizard, and other skeletal remains of extinct species in Tenerife such as the Rook and the Houbara Bustard.

Tenerife Water Supply, where does it Come from?


It is a question that is often asked by the tourist and in fact some residents 'Where does the water come from?

It seems strange to a lot of people that an Island as small as Tenerife, should have, what seems like a never ending flow of water, after all it doesn't rain very often.

'THE PINE FORESTS' that is the answer to the question.

The pine trees collect the water from the dew at night, the clouds that at times cover the mountains, the rain fall when it comes and the water from the melting snows during the winter months.

All this water passes into the ground via the roots of the pine trees, where it sits in natural underground reservoirs.

It was the Arab's, experts in transforming dry land into arable land, who introduced irrigation into Spain, the Spanish conquistadors passed on the knowledge to the Canary Islands , adapting to the conditions and materials of the Islands.

Villages grew around the natural springs, as villages grew the water had to be carried further afield for domestic and agricultural use.  This was achieved by the way of concrete and stone channels, directing the flow of water to the desired location.

As the population of the Islands grew, so the necessity for more water grew. So the search for more  began.

The underwater reservoirs are found by boring deep into the ground, when the water reserve is found the boring stops and horizontal excavations  begin to reach the water supply, these excavations are known as galleries.

The water naturally flows to the exterior for domestic and cultivation use, sometimes depending on the location, the water has to be pumped.

Although it would seem that there is an abundant supply of water, great care is and needs to be taken in the amount of water that is used.

The pine forests are essential to the Island and have to be watched constantly to avoid any kind of fire accidental or malicious damage.

Walking Trails - Camino Real de Fasnia, Tenerife

This is one of the many walks on the Island of Tenerife, which takes you through some of the fantastic countryside , at the same time pointing out historical facts of which Tenerife has plenty.






The track starts in the centre of Fasnia, by the cemetery area, just at Carretera Los Roques Nº 1.



You can do the route in two different ways, south or northbound, along the old Royal road. The north track follows an unpaved road among some old houses, of great interest (traditional architecture), until it meets another unpaved road. You go on along this road amid terraced fields, some of which are abandoned; others have potatoes growing in them. You get to a crossing with a paved road. Here you find a little hamlet, Camino Real on the right of the track. Once on the paved road, you go on for some 150 m. at which point you turn left into a path leading us to the bed of the Herques ravine, where you see the original cobblestones. The ravine is an area of a great interest as regarding the flora. We find all sorts of local species, such as spurges, and Peripocla Alcurnico etc. The presence of the Caves of Herques add an archaeological interest; they used to be one of the dwellings of the Guanches, the ancient indigenous people of the island. 


The south track takes a diversion, on the left, towards Fasnia Mountain (Montaña de Fasnia). This volcanic cone is 403 m. high and the flora you can find there is mainly cactus spurges. The summit of this volcanic mount is a natural view-point where you can enjoy very interesting views of the whole town of Fasnia. At this point, the old and the new chapel of La Virgen de los Dolores is to be found. 
Once at the base of Fasnia Mountain, the track follows along the Royal Road again until it meets San Joaquín ravine, where the ruins of the ancient San Joaquín´s Hermitage can be appreciated. This hermitage was built in the XVII Century. The track follows along the bed of the ravine where caves of a great archaeological interest can be found, then, it crosses the Bridge of The Three Eyes (Los Tres Ojos). The C-822 road goes over the bridge and follows until a water gallery, which is the end of the track.
