I have done only the southern half part of this route and it’s really great. Nice corners and spectacular views. I assume that the northern part is the same cause is marked as a scenic route in my Michelin map.
This is a perfect route on Carpathian Mountains with spectacular scenery, perfect tarmac and great corners. The traffic is high cause is the main road the connects Bucharest with the northern Romania.
It’s a scenery only road, passing beside lake Rosu (Red lake) and the spectacular Bicaz gorges. The road condition is awful with lots of potholes and huge traffic.
