An ascent with two sections, of the same length, with different characteristics. The first part is on a road with greater than average gradients overall, fairly sheltered from the wind, moderately busy but with a wide roadway and asphalt in good condition. When we arrive more or less at the point where there is a slight descent, the second part begins, characterised by gentle, even gradients. The carriageway becomes narrower after a while and the road surface is less even. There is no shortage... read more

An ascent with two sections, of the same length, with different characteristics. The first part is on a road with greater than average gradients overall, fairly sheltered from the wind, moderately busy but with a wide roadway and asphalt in good condition.
When we arrive more or less at the point where there is a slight descent, the second part begins, characterised by gentle, even gradients.
The carriageway becomes narrower after a while and the road surface is less even. There is no shortage of wind here and in the most exposed hairpin bends it can be annoying.
I last rode this route in August 2025 and had some problems with insects, which were really annoying.

Salita con 2 tratti, della stessa lunghezza, con differenti caratteristiche. Nella prima parte si percorre una strada con pendenze maggiori della media complessive, abbastanza riparata dal vento, moderatamente trafficata ma con carreggiata ampia ed asfalto in buone condizioni.
Arrivati più o meno dove si percorre una leggera discesa, inizia la seconda parte caratterizzata da pendenze dolci e regolari.
La carreggiata diventa più stretta dopo un poco ed il fondo stradale é meno regolare. Qui il vento non manca e nei tornanti più esposti può essere fastidioso.
L'ultima volta l'ho percorsa in Agosto 2025 ed ho avuto qualche problema con gli insetti, davvero fastidiosi.

A long climb but with uncommitted losses, the road is well paved and the roadway is wide. There is a strong headwind in the final section. I rode this climb in May and did not encounter any cyclists.

Salita lunga ma con perdenze non impegnate, la strada è ben asfaltata e la carreggiata risulta ampia. Nel tratto finale si può trova un forte vento contrario. Ho percorso questa salita nel mese di maggio e non ho incontrato ciclisti.

I ride this climb habitually as a less than amateur cyclist, with few annual outings. Not steep but long and with stretches that present a minimum of difficulty, with a gradient of 9% for about a kilometre just after the junction for Campoli Appennino a third of the way up... A scenic road, very beautiful, trafficked by motorbikes that often ride along it at high speeds. It is a natural training ground for cyclists, a natural gateway to the Abruzzo, Lazio and Molise National Park. At the end of the 29km, you arrive in a stupendous forest and then begin the descent to Opi, from there, for those with legs, you can continue to Passo Godi and Scanno, adding kilometres and elevation gain. I recommend it to everyone because it is rideable but also a good test for those who live the bike without ambition but who seek personal satisfaction.

Percorro questa salita abitualmente da ciclista meno che amatore, con poche uscite annuali. Non ripida ma lunga e con tratti che un minimo di difficoltà la presentano con pendenza al 9% per circa un km appena dopo il bivio per Campoli Appennino ad un terzo del percorso... Strada panoramica, molto bella, trafficata da moto che spesso la percorrono a velocità sostenuta. È una palestra naturale per i ciclisti, porta naturale per il passaggio nel parco Nazionale Di Abruzzo, Lazio e Molise. Alla fine dei 29km si arriva in un bosco stupendo per poi iniziare la discesa verso Opi, da lì, per chi ha gamba, si può proseguire fino a passo Godi e Scanno aggiungendo km e dislivello. La consiglio a tutti perché è pedalabile ma anche una bella prova per chi vive la bici senza velleità ma che cerca soddisfazioni personali.
