We have cycled the del Norte so far only from the border as far as Gernika, on touring bikes. We have not taken any off road routes and do feel that we may have been missing out on some special places. So we are wondering whether to continue on this route on foot.
For example: Sometimes (well, usually) when we could have taken a side trip to a particular village mentioned in the guide (we were using the CSJ Eric Walker's one, which is rather confusing and needs a good editor) we couldn't face it because it would have been a two-way deviation with no forward progression, usually with one steep climb involved, and because we had a long way to go to the next refuge for the night. Mind you, we were at the end of our trip and our (Bridget's) legs were getting tired and there were a LOT of steep climbs. Sometimes it seemed that the walking route would have been much more satisfactory - for example from the monastery at Zenaruzza (high above the village of Bolibar) we had to cycle back down the steep hill we had come by, immediately up a very long drag that took us ages and ages and brought us higher than the monastery (which was just across the valley by this time) and it was much further on when we crossed the walking route which had been able to contour round the head of valleys in a much more pleasant way! Eric says for this bit :
There are now arrows marking a new and quite involved route, I have not walked it but I am, given to understand that it can be very heavy going if the weather is bad... I will describe the route which I took and which is suitable for cyclists if the are willing to push and carry a little on the first section ... shortly turn left up a short ,slippery track...
You can see why we chose to follow the roads!
NB the mentioned dormitory accommodation at the monastery was awfully bleak and cold looking (and we are not easily put off) in October, with no facilities other than a loo, as far as we could tell. The friendly hotel nearby has lovely refuge facilities with a kitchen, plenty of showers and bar and restaurant if you want. The monastery itself is well worth visiting.
One day soon I will complete the account on our blog which should show the route we took on out bikes.
