Asphalt Logrono - Burgos?

There is asphalt, but also some packed dirt trail. When possible, the path is parallel to roads but off the road.

Welcome to the Forum.

I've done the Camino only once but, from my recollection, I would say 'no' there's not a lot of asphalt on this stretch. There is asphalt along the way but mainly it is packed dirt, as falcon says. There is a long stretch of concrete walkway leaving
Logroño (and entering it too) that seemed to go on forever, which I found very hard on the feet. The walk into Burgos seemed interminable (that's asphalt and concrete!) but, when we got to the river, it was a pleasant two hour walk to the cathedral.

Buen Camino!
