Between Baztan and Etxalar, a pleasant path runs parallel to the “Mill from Hell” (Infernuko erreka), which leads to a hidden place containing a historic mill. The villagers made corn flour here, and it is said that it was the only one that continued grinding secretly during the civil war. The construction was fully restored and is open to the public.
The walk begins in the village Lekaroz (Orabidea), accessed by the NA-4403 road.
