Solo but not alone...
The Camino Forum offers a calendar who is traveling when. if you wish, you can add your trip start date and starting point to a monthly calendar on the Forum.
Since you sign on with an alias, you can post that information without exposing your email address etc. If you wish, you can then write to others who are travelling from the same point and offer to connect when in Spain.
I've heard tales about arriving in Paris or Madrid or Biarritz as a solo traveller embarking on a Camino and being greeted by others with backpacks about to do the same thing.
Pilgrims walk different routes- there are many many Caminos. I'm walking the Camino Frances, which starts at the foot of the Pyrenees in France, at St Jean Pied-de-Port.
Others walk the Primitivo, the Portuguese, the Norte, the Angles, Le Puy, La Via de la Plata - these are all various Camino routes that funnel into the destination in Spain- Santiago de Compestella
And LOTS of people now walk the Camino each year. Numbers have been rising substantially.
