Year-round conditions for cyclists

• Expect snow and ice frequently at this altitude in the southern Alps.
• Roads may be temporarily closed or impassable, especially after storms.
• Even when technically open, shaded sections can stay icy all day.
   Cycling: usually not recommended unless warm, snow-free winter spell.

• Highly variable:
  • March → often still winter-like.
  • April → melting snow, wet roads.
  • May → mostly rideable.
• Rockfall and debris possible after snowmelt or rain.
   Cycling: reliable access usually from mid-April to May, depending on year.

• Generally fully open and dry.
• Temperatures comfortable due to altitude (cooler than valleys).
• Occasional thunderstorms in afternoons.
   Cycling: best season — stable conditions, scenic, low traffic on smaller approach roads. 

• September–October: excellent riding — crisp air, clear visibility.
• November: increasing risk of frost and early snow.
   Cycling: great until late October most years.

• Mostly paved but some segments nearby routes may be rough or partially unpaved, so tire choice matters. 

Typical opening period

What cyclists should expect

• Quiet rural climb through a remote valley. 
• Moderate gradients but can feel tough due to exposure and length of loop rides nearby. 
• Watch descents — some surfaces reported not in perfect condition.
