Erlengarria VIII

From the facilities of the recreational area of the Leurza reservoirs, head toward the dam of the second reservoir along a track running southwest, following the left-hand branch after the fork. Once past the dam, take the track on the right that skirts the upper reservoir, crossing the river of the Erlengarria spring 13, until reaching a new ascending track on the left. Following this, one arrives at a change of direction to the right, which leads to marker 37. Once at the marker, skirt uphill alongside a wire fence, turning with it to the left for about 20 metres. From here ascend for about 70 metres, reaching the caves of the Mojón. From this point take the left-hand side a little higher up, continuing in this direction for about 50 metres, until reaching the mouth of the cave.
