This great mountain route (GR) is the longest and hardest of those that make up the network of trails in Gipuzkoa. It links Elgoibar with Hondarribia over a distance equivalent to three marathons. It crosses the five most important rivers (Deba, Urola, Oria, Leitzaran and Bidasoa) and several mountain ranges (Karakate-Irukutzeta, ZEC Izarraitz, ZEC Ernio-Gazume, Adarra, Aiako Harria) through the interior of the territory of Gipuzkoa. These characteristics explain the choice of the name: Mendi (mountain) and Ibai (river).
