As a person who has done many legendary routes (Transfagarasan, Transalpina, Stelvio etc.) I am telling you "Do not die before you ride this route."
But be cautious, the elevatiton goes up to 1.800 meters, best between mid-may until mid-september.
Spectacular curves, transfagarasan style road views, so far away from residental presence.
Recommended that you take the road from Ioannina (west of Pindus mountains) and ride from west to east.
Nice open motorway with lots of corners that goes through mountains. If you like to ride fast and you like corners, this is the road you should choose. Nice surface, almost no surprise ahead, open visibility. If you are slow rider you may get bored.
A nice route when you're coming out of a great meal you had on top of Domanic mountains if you intend to go south. Great scenery. Best at spring.
