For the second section (after the junction with the D431, an excellent road, also listed here) it's a really nice if a bit hairy run from the lake, down to the bottom. Be careful here as it can be difficult to scrub off a lot of speed safely. Otherwise excellent.
Spectacular views and some good corners (these would be rated as excellent in most other regions, but here, the standard is so high). Visibility can be restricted bycloudsd and watch out for camper vans. Road surface ok but starts off a bit patchy.
