Boca del Infierno consists of several collapsed fragile holes in one lavatube.

The entrance is situated within the updated borderlines of the National Parque Timanfaya.

So in principle it is not allowed to visis this arae without permission.

The cave and surroundings are very fragile, floors can collapse!!

Due to this fragile-ness and for conservation reasons it is not  adviced to enter the cave!!

The main gallerie consists of an exploded gasbubble, as can be seen from outside by the existing small hill.

In the main gallery through a small crawl the continuation from  the lava tube can be found ending after several meters in a vast wall.
