Adi IV

The cave is located on the orographic right bank of the Odia stream, about 40 m above its level. Take the paved track of the Sorogain ravine to the confluence with the Odia stream; from here you must go to the hollow formed by the Adi and Iturrumburu mountains. Take an ascending path that climbs parallel to the stream with red-and-white Gr marks up to a fence that closes the way. After a few metres you reach the entrances of Adi 3. Follow the stream for 50 m, before it divides into two channels. Climb to the left about 20 m over clayey-sandy schists and another 20 m more to reach a karst where the cave is found.
