3 hours road, expandable with two more descents (see variants). The ascents are comfortable on pavement or by trail and the descents by enduro paths; all have a very high quality, with side trips at the beginning and then linked curves and photogenic areas in Espierlo, Sives and Seso (semi-uninhabited).

La sierra Ferrera es un filón de senderos. Te proponemos una ruta de unas 3 horas ampliable con dos bajadas más (ver variantes).

Las subidas son cómodas por asfalto o pista y los descensos por senderos son endureros y de gran calidad, con travesías a ladera al principio y luego bajadas con curvas enlazadas y zonas fotogénicas en Espierlo, Silves y Seso (medio deshabitados).

El río Ara saliendo del cañón de Jánovas nos proporciona el marco ideal. Lo iremos oyendo cada vez más fuerte a medida que descendemos. Te va a gustar sin duda.

Tipo de bajadas: “Stone flow” algo cañero y bosque limpio.

Fuente: Boltaña.

Variantes «trilogía» y «tetralogía de Silves: Puedes alargar esta ruta volviendo a subir a Silves bajo por pista empinada. Empieza bajando por «Silves medio» (recuperado en 2013) y si aún resistes, vuelve a subir y hazte un Silves bajo, más trialero y pedregoso que el anterior.

Caliza, abierto y bosque

Todo el año.
Ideal para días de lluvia, solo hay que tener precaución con algunas losas después de Espierlo.
