Apart four days spent crossing the flat plain in the Navarre and two days approaching the Mediterranean coast the GR1 is a walk through the mountains. In the west it's a journey through the Cantabrian mountains and in the east the foothills of the Pyrenees.
An important feature of mountain walking in Spain, unlike much of Western Europe, is that you don't have to get above the tree to enjoy the wonderful views. Mountains at similar altitudes in France, Italy, Switzerland and Austria are more likely to be covered in trees, often commercial pine than in Spain. In these countries you can sometimes walk for days without getting 'a long view'. As in othercountries Spain lost its trees (and topsoil) to agriculture and woodburning centuries ago but because rural depopulation happened so much later trees have not yet returned to cover the mountains.
