Top 4 Caves 아라시아-네르비온 주변

Lezabaltz (from "leza" (chasm) and "baltz" (black) in the local Basque) is the name given to one of the ten access points to the Austegiarmin karst drainage network. It is an impressive chasm, with a wide mouth and 35 meters deep, well known to the shepherds of the main sheepfold in Orozko (Bizkaia), whose huts are located just over 100 meters away in a straight line. Be very careful!

Like the Baltzola caves, it is now prohibited to cross them, due to the danger of Q fever.

This part of the Baltzola caves was normally the exit.

Impressive cavity, until a while ago you could go through. They have recently put up a sign, warning of the danger of contracting Q fever, and the passage is prohibited.

Cave inside the so-called Great Central Crack, in the Itzina Massif. Its interior can be accessed by descending the ramp of the natural tunnel from the mouth of Axlegor, municipality of Orozko (Bizkaia).

In the rainy season, you may not be able to cross the tunnel without getting your feet wet. But it is impressive to find this at the beginning.

One of the most beautiful caves I have ever seen. First because of the location, second because of the small challenge of not getting lost to get there, and thirdly because it is super cool: a huge mouth and easy to travel (with a flashlight) a good stretch. Absolutely recommended.

Beautiful area, it is recommended or almost mandatory to carry a flashlight, since although the cave is short and does not involve much difficulty, it is always good to see where you put your feet
