GR 121: Guipúzcoa Round Trip
The province of Guipúzcoa is one of the smallest on the Iberian Peninsula, although this is not an impediment to it presenting a wide variety of countryside.
The ocean and the cliffs are impassable steep rocks that attract your attention.The remainder are mountains bordering Vizcaya, Álava, Navarra and Lapurdi/Labourd. Its geographic distribution seems forced to fit in all of its elements: narrow parallel valleys running from north to south in which the localities are located, and on the slopes the country houses, distributed in pursuit of certain independence.
