Obiarena I

From Goñi, go up the track that reaches the Ermita until, after 10 m, you come to the second walkway of iron sleepers crossing the track; here the cars are left to go into the forest. From these same sleepers a path sets off, in a Northerly direction, that in 5 minutes brings you to the ruined bordas of Obiarena. From these, in an easterly direction, take the edge between the clearing and the forest and, over descending ground, reach the first entrance in 2 minutes, at UTM coordinates X588320 Y4745725 Z1129. To find the second entrance, at coordinates X588245 Y4745700 Z1135, continue from the first in a northeasterly direction for 25 or 30 metres until you come to some steel wires that surround the entrance shaft.
