As through the years a lot of investigations and reconnaissance has been done in Lanzarote. Some of this information has been lost already .  This website tries to fill in this gap, to overcome the problem in this time of enormous amounts of electronic information, to gather all available information at one place. Both  scientific research as well as reconnaissance  and information of just enthusiastic cavers.

These pages are all about  caves on Lanzarote. Volcanic underground  phenomenons which are accessible to human beings. In casu: Lava- flow-tubes, Pyroclastic caves, volcanic vent shafts, eruption shafts and former geijsir.

2 enthusiastic speleologists are gathering this information and putting them on this website. Laurens M.J. Smets from Speleo Nederland (The Netherlands) and Gustavo David Santana Gomez from Vulcan Vertical (Lanzarote) . 

As most caves and volcanic phenomenons are within a geological protection program (UNESCO, National Park, etc)  and are protected by law , it is mostly not allowed to visit these caves.  For this reason for most caves you will not find their exact location and no coordinates are mentioned. 
In some cases a permit can be obtained from the appropriate institute. For contact view our LINK page.

We hope with this inventory we  can add some value on the work of  scientists and authorities with  their protection- and conservation programs  of these unique underground lava-cave features.


If you want to obtain high quality surveys or pictures for publications reasons please contact us by filling in the CONTACT page 

All locations from entrances and survey data are known to us. When you  want to obtain coördinates or survey data please lett us know.

Due to protection and conservation reasons we only provide this information to official Institutes
