A guidebook to trekking the GR1 Sendero Histórico through northern Spain. Suitable for fit experienced trekkers, this quiet 1247km (775 mile) route stretches from Puerto de Tarna on the edge of the Pico de Europa National Park, across the southern flank of the Cantabrian Mountains, through the Basque Country and Catalunya, to Sant Martí d’Empúries on the Mediterranean coast, and can be completed in around two months.

The GR1 is divided into 53 stages of 11 to 36km (7–21 miles). These are presented in 7 sections, with start and end points that are easily accessed by public transport, for the benefit of those who wish to walk only part of the route. An extension to Finisterre and the Atlantic using GR routes is also included.
