The Camino de Santiago consists of a set of pilgrimage routes that have existed for over 1,000 years. The routes have various starting points, but all end at the Cathedral of Santiago de Campostela in northwestern Spain. The Camino Inglés follows the route traditionally walked by pilgrims arriving on ships from England, with starting points Ferrol (113.45 km) and A Coruña (~73 km).

The route starts around 3100m in Plantat Refugee, from there, there is a mix of trail, rocks, penitentes and a glacier that converge at 5500m. Until this point, this is the same route for San José Volcano (5856m). At 5500m it is where the path divides: To head towards Marmolejo it is necessary to descend 500m, crossing a glacier, frozen lagoons, always appreciating clearly Marmolejo, at first a massive mount that is necessary to climb again.

Walk 17 – Teltow Canal Walk (38 km)
