Very nice ride,you will love the open scenery of the Julian Alps while riding on wide curves. DON'T miss the Mangart Pass (see details in next section), however the road surface becomes poorer just after but it's not a big deal.
The well known passo Predil
that connects Italy with Slovenia.
A great and quiet road with great views and
some great corners (specially at Italy side).
There is a new highway building over this area so
probably you will meet roadworks
(when I was there it's was near Mangrt pass).
