Based on when. We hiked the Norte and then the primitivo 2 years ago, we had great weather, hardly any rain and the up and down on the primitivo was fabulous. Spend some time in Lugo if you can spare, the Roman ruins are great.
We walked the Norte starting the week before Easter, it was busy for the week before and after as a lot of people had to use up their vacation time. Plus the schools are out for quite a bit of time then also. Overall it is still okay to go a bit busier but fine.
