Cuando hagamos esta ruta por momentos pensaremos que estamos en una selva de Birmania, pero no, las moles pétreas del pirineo muchas veces nevadas nos devolverán a la realidad.
Y es que nos adentramos por las gargantas del río Irués, un lugar recóndito y verde. Veremos mucha agua, primero por la Garona, despues por el Irués y finalmente por el Cinca.
Muy recomendable en verano y días calurosos puesto que en general la ruta es muy refrescante. También cuando hay barro en otros sitios. Aquí no se genera.
Tenemos la opción, muy recomendable, de visitar las fuentes de Fornos con la bici, y a partir de ahí a pie hasta el Chorro de Fornos, por donde sale el agua a presión desde un agujero en la roca a 10 metros del suelo.
No hay que olvidar que tenemos un 40% de sendero de alta calidad y muy fotogénico. No esperes grandes descensos que agoten los frenos, pero sin duda no olvidarás esta ruta.

Tipo de bajadas: Variado. Selvático con hojarasca, después seco y sendero de ribera suave y agradable al final.

Variante “Subimos a la Collada”: Alargamos mucho más la ruta y nos asomamos a la cara norte de la Peña Montañesa. Es menos técnica porque va casi todo por pista, salvo la bajada por PR a Badín y el GR final junto al río Cinca.

Lugares de Interés:

Chorro fornos
Pozas del río Cinca.

ZZ008 La Selva de Iru s


Easy route technically although hard on the physically. Climb the famous Collada de Ceresa to 1548m by the north side of Peña Montañesa.

We will have excellent views from the summit and then we introduce what the locals call “La Valle”, a cool and dense area of woods, bear sanctuary.

The final check is done by GR-19 from Badain following the left bank of the river Cinca. Unless concrete steps the route is accessible to a frequent rider.

Variant “winter version” La Collada has snow in winter and therefore we take a lower track, we add more path and spice, passing through the ford of Irués with dense area of woods
