Amazing road from the the Svaneti capital Mestia to UNESCO town Ushguli, famnous for their unique defene towers. About 40km of road, two thirds amazing twisties on asphalt, the last third is dirt. Doable on 4WD and Adventure Bikes. Dirt road will turn into mud after heavy rain. Be careful in the main tourist season as the dirt road in a lot of places only has place for one car, and there is a lot of 4WD taxis carrying tourist. None the less you should not miss out if you are in the area.
