The Alto de Ixua is an iconic mountain pass in Eibar, with steep slopes that make it a classic Basque cycling route. From its summit, you can enjoy sweeping views of the mountains of Gipuzkoa and the industrial valley of Eibar.

The road leads you to the legendary Arrate Sanctuary, a historic summit for Basque cycling and the final stage of numerous editions of the Tour of the Basque Country and the Tour of Spain.
