The GR100, or Silver Route, is a 705 km point-to-point long-distance trail across western Spain, following the Vía de la Plata from Seville to Astorga. Allow about 30 days. It is a hard walk: not technically difficult, but demanding because of long stages, exposed plains, sparse water and extreme summer heat. It suits experienced long-distance walkers and Camino hikers who want a quieter, more historical alternative to the Camino Francés.

Route Overview

Walked south to north, the GR100 starts in Seville, crosses Andalusia and Extremadura, then enters Castile and León before ending at Astorga. Key places on the line include Zafra, Mérida, Cáceres, Plasencia, Baños de Montemayor, Hervás, Béjar, Salamanca, Zamora and Benavente. From Granja de Moreruela the pilgrim route splits: walkers going to Santiago take the Camino Sanabrés west, while the classic Vía de la Plata / GR100 continues north to Astorga. Compared with busier Camino routes such as the Camino del Norte or Camino Primitivo, the GR100 has wider spacing between towns and needs more careful stage planning.

Roman road, droving route and Camino variant

The Vía de la Plata was built by the Romans as a paved military and commercial highway linking Emerita Augusta, modern Mérida, with the south near Seville and the north at Asturica Augusta, modern Astorga. It became one of the major routes of Roman Hispania and is still marked by Roman remains including bridges, milestones and old towns. Later it developed as a medieval droving route and an alternative Camino de Santiago. The name “Plata” is widely held to derive from Arabic “al-balat”, meaning paved or cobbled road, rather than silver trade.

Notable highlights

Mérida: Founded as Emerita Augusta in 25 BC, this Roman city is a UNESCO World Heritage Site. The route passes close to major Roman remains including the theatre and amphitheatre complex, bridge and aqueduct.
Cáceres old town: A UNESCO-listed walled centre with Roman, Moorish, Gothic and Renaissance layers. It is one of the most atmospheric urban stops on the Extremadura section.
Cáparra Roman arch: A rare four-sided Roman triumphal arch near Oliva de Plasencia, standing on the line of the abandoned Roman town of Cáparra. The path passes directly through it.
Calzada de Béjar: A preserved section of original Roman paved road climbing through the Sierra de Béjar in Salamanca province. It is one of the clearest places to feel the ancient calzada underfoot.
Salamanca: A UNESCO World Heritage university city known for golden sandstone architecture, the Plaza Mayor, two adjoining cathedrals and its historic university.
Astorga: The northern terminus of the GR100 and the Roman Asturica Augusta. Hikers finish among Roman remains, a Gothic cathedral and the Episcopal Palace designed by Antoni Gaudí.

Challenges to expect

Expect endurance rather than technical scrambling. Daily stages are often long, with 25–35 km days and some 20 km-plus stretches without villages or water. Much of the route crosses open dehesa, cereal plains and quiet rural tracks with little shade. Mid-summer heat in Extremadura and Castile can reach 40–45°C, so spring and autumn are safer. Waymarking is usually straightforward, but some agricultural sections are sparsely marked.
