I walked from Sevilla to Ourense may 2008. In the start it was very hot, about 35 celcius, but it got cold an rain when I come north. There are not many pilgrims on Via de la Plata, but you will meet some every day.
I am going the camino Via de la Plata again from 15. may 2009 an this time I am going all the way to Santiago de Compostela.
I have gone the Camino Fraces 2005 and 2007.
