Depending on the type and style of each cyclist, this route can serve different purposes.
If we speak of accomplished cyclists it may serve to unwind and make a good touchdown, filling one evening after a long car journey.
If we speak of occasional cyclists or beginners, this route will allow them to make a day of cycling that goes through high zones across the higher cycling point (asphalt) in the area and foresee the essence of the big descents and ascents of the northern slope in the short distance between the top of the port and the ski resort of Arette.

Dejando atrás el llano de Belagua, ascenso a La Pierre de St Martín por Isaba.
Tras un primer tramo en suave ascenso hasta la Mata de Haya se afronta un sostenido muro de 8 km al 7% con alguna rampa de 9 y 10%.
Otros 6 kilómetros algo menos exigentes nos llevan atravesando el complejo kárstico de Larra a la cima del Portillo de Ernaz, comúnmente denominado La Piedra de San Martín, punto culminante del recorrido (1762 m).
El pico Anie sobre el karst de Larra, territorio pirenaico con ambiente propio.

Después, breve descenso entre pastizales con olor a vertiente norte hasta los edificios de la estación de esquí Arette-La Pierre Saint Martin.
Arette
De vuelta al puerto remontamos los 2,5 km antes descendidos, 6% con algún pequeño tramo al 12% y descenso rápido y limpio hacia la Mata de Haya.
Contemplar la posibilidad de seccionar dicho tramo realizando una parada en la histórica Venta de Juan Pito en la parte media del puerto. De la Mata de Haya a Isaba llaneo con tendencia descendente.
Descenso de La Pierre de St Martín de vuelta a Isaba
We are where we are, in the Atlantic Pyrenees, with a plain to the North with localities at very low altitude and ports that are close to the 2000m range.
The southern slope is more "human", towns are in a higher altitude and the slopes are not so important.
The vast majority of the routes cover the ports of the "greats": Issarbe, La Piedra de St Martin, Laberouat, Bagargi, Artaburu, Arnostegi, Ahuski, Larrau...with slopes ranging between 1000 and 1700 meters. Some routes ascent one of these ports, others 2 or 3 and even more.
We anticipated this so the criteria are clear for each 6 levels that we have chosen for the ranking of the routes.
