Not far away from the Residence there is a passage that not many of us might have discovered. It connects two parts of Oñati, is approximately 333 meters long and partially goes in a tunnel. Officially it is called Lazarraga Kalea but I prefer to refer to it as a secret passage. It has beautiful pergola roof foliage at the east exit. You can use it to go for a Wednesday pintxopote to San Lorentzo part of the town, if you have already been to all the bars in the center.
