Yes this brings back less than happy memories. I came upon this sight (on my bike) and took a long hard look at it. Then I found (or was directed to) an over grown track the detoured around these steps. But I still had to climb up the other side - no detour this time. Note to cyclists - from Cirauqui follow the sealed road out of town (I think its sign-posted to Estella/Pamplona/Logrono) and turn onto the N111 (not the A12 - cyclists not permitted on autoways/motorways). Great photo!
