From here to St-Croix: uphill tight turns requiring experience, nice long stretches with smooth bends

From Bullet to Mauborget: very scenic, straight, smooth bends, excellent surface

Follow road to the right and start descending towards Grandson. Beautiful views on Lake Nauchatel.

Very nice ancient village with café/restaurants (I did not stop, though).

From Orbe to La Sarraz: very fast stretches of smooth road, low traffic
