From Thessaloniki or Athens you may wish to drive to Kastoria. The journey is approximately 2 1/2 hours from thessaloniki, 5 hours from athens, without stops. However the route takes you through some beautiful scenery, so you may likely want to make some rest stops along the way. The Meteora, situated in the city of Kalambaka is a great place to break up the drive, coming from Athens.
If you still want to view the scenery, but do not want to drive yourself, there is a shuttle company (KTEL) which make the trip from Thessaloniki or Athens to Kastoria several times per day. You will be dropped off at the Kastoria city Centre, just a few steps away from the car rental agencies.
