Pila Les Fleurs: The Charvensod Road Above Aosta

From 569 m (1867 ft) at Pont Suaz to 1404 m (4605 ft) at the Les Fleurs junction is 12.2 km (7.6 mi), with 835 m (2738 ft) of gain at 6.9% on average.

The climb is front-loaded. From the start to about 9.5 km (5.9 mi) it averages 7.6%, and the 4.5-8.5 km stretch above Charvensod holds 8-10% almost without a break. The steepest kilometer averages 9.7% and the hardest 5 km (3.1 mi) 8.5%. The one real breather comes between 3.5 and 4.5 km (2.2-2.8 mi), where the grade drops to about 5%.

Over the final 2.6 km (1.6 mi) the road eases to about 4% on average, with a near-flat section around 10.5 km (6.5 mi), before a last gentle rise to the junction.

Gear: Nothing here is brutal - no full kilometer reaches 10% - but the long middle section at 8-10% wants a gear you can keep turning for the best part of an hour. If you're going on to Pila, bring a layer: the resort is 400 m higher than the finish and the descent is long.

Provisions: Stock up in Aosta or at Pont Suaz. Once you're above Charvensod there's little until the resort itself, where the bars and restaurants of Pila are 4.8 km past the finish.

Aosta makes the easiest base: the old Roman town of Augusta Praetoria still has its Arch of Augustus and the Porta Praetoria gate in the center, plenty of hotels and restaurants, and trains down the valley toward Turin. Pont Suaz is only a couple of kilometers from the center.

The natural extension is to keep climbing from Les Fleurs to Pila - our Pila page covers the Gressan road the Giro used in 2026, and descending that way makes a good loop back to Aosta. If you'd rather not ride down at all, the gondola links the resort with Pont Suaz.

Across the valley there's a lot more within reach - the Colle del Gran San Bernardo, Verrogne and Saint-Pierre-Vetan all start a short ride from Aosta, and Routes in the Area, on this page, shows how they fit together.
