Pretty close to the highway, so sometimes a little bit noisy. Usually you don't really hear the cars - you're climbing after all.

The sector dries quickly after the rain, it's situated on a hill, so there might be wind when the other areas are still. It might also make this sector cold when the weather is chill.

The name comes from the three big boulders (where Matiere Gris is). And Drei Zinnen comes from Italian Tre Cime, which is a famous place to climb at Dolomites.

The orange and the blue circuits are newly renewed (as of writing in 2018) and they are very nice indeed. They run along, so you can climb both at the same time.
