BZ-6

To reach the BZ-6 cave, take the NA-7182 road that crosses the Urbasa Park from Zudaire towards Olazagutía. At kilometre 30.900 of this road begins an asphalt track (Otsoportillo track), which is followed to kilometre 4.100. You come to a junction with an easily identifiable parking area, since another pit with a protection wall can be seen; if you do not have permission, the vehicle must be left parked here. Continue along the gravel track (Etxarriko Sareetako Bidea), which leads in the direction of the hermitages of SANTA MARINA and San Adrián. You must walk 1.6 km until you find a fork to the left that must be taken (Santa Marinako Pista). You go down and up through some zig-zags until you find some bordas on the right-hand side (Majadas de Iturmendi), a few hundred metres before reaching the hermitage of SANTA MARINA. You will have covered 1.4 kilometres more to the bordas, where you can park. You walk about 990 metres in a N-NE direction, without entering the wooded area, and stay beside the escarpment that overlooks the Sakana valley, where the fallen Oineta menhir can be seen, UTM ED-50 573.349 - 4.747.400 - 1075. They are 840 mts. apart. You enter the beech wood and come out at the Baiza open ground, where the cave is located, at the limit of DEL BOSQUE with the pasture area.
