|GR7 footpath between Nechite and Válor (Alpujarras)|
This footpath is long! It starts at Tarifa near Gibraltar crosses the coastal mountains of Spain before continuing across the Pyrenees. However, this is only part of the story. The GR7 is but one section of the 'European Route No.4' or E4, a 10,500 kilometre footpath that runs from the southernmost point of Spain all the way to Greece via France, Switzerland, Austria, Hungary and Rumania.
