Best to do it from W to E.
Mediocre road condition from Szokolya down to the Danube, otherwise great surface. Mountain strech pretty narrow but awesome.
Not a lot of things in the area, but those hills and turns are niiiiice! Szekszárd is definitely the region's capital for wine. Don't miss.
Short section but nice scenery. Winding road. Don't miss
Start from Karlobag: from sea to 935 meters in 17 km: 8 nice hairpins. Then very nice undulating road thru Gospic until Gracac. Good straights, wide road. After Gracac go down to canyon road. Extreme scenery, narrow but good road, completely deserted, like UTAH. We loved every yard of it.
average on traffic, lots of stretches to overtake. Practically no more than 100m straights... Summer of course full of goddamm campers but really exceptional scenery of Island Pag (like Moon)
