San Miguel de Áralar is a sanctuary with more than a thousand years of history, at an elevation of 1.220m (4,002ft) above the sea level, located in the province and autonomous community of Navarre, northern Spain. The road to reach the summit is called NA-7510.
This is a first category climb. It's relatively steep, and for much of the way it is concreted rather than paved. This is 11km at more than 8%, much of it on those same rough, unforgiving concrete roads. The maximum gradient is 17% at the very top; though the climb never has any truly brutal sections, it is continually tough, with several kilometres at over 9%, a handful of stretches of 15% or so, and the climbers will need to make these 11km count, since this is the final roll of the dice.
The drive is definitely worth it. Don’t forget your camera! The sanctuary is located at a strategic point on the peak of Mount Artxueta which can be accessed by road from Lekunberri and gives a spectacular view that encompasses the Arakil or Barranca corridor, San Donato and the sierras of Urbasa and Andia.
