What a lot of fuss to avoid passing an attractive golf course with an excellent bar and restaurant. The length through the partly developed residential area at Cirueña is just over 1km, less than 15mins easy walking. It is reached by an attractive hedge lined track gaining height steadily with great views back towards Najera, while the descent has even better views ahead to Santo Doningo.
The alternative following the N120/A12 is horrid. This is one of those places where construction of the A12 motorway has obliterated parts of the former N120. A new route for the road has been built N of the motorway but this is not great walking on a modern asphalt highway with no
senda. There is an incomplete path beside the A12 using disconnected remnants of the old road but in two places this disappears completely under the motorway embankment for a short distance. I explored both routes when I was trying to find a cycleable alternative route for my Cicerone guide to
Cycling the Camino Frances and would definitely not recommended the highway as a walking route.
