Katerini Transportation

The bus system in Greece is really bad, especialy for tourists. The schedual makes no sense. Despite the fact that it's written in Greek, the times are inaccurate, i.e. our bus arrived 15 minutes later then it was suppose to.
The connections are also really bad. We were traveling to Dion and had to change buses in Katerini. Our driver didn't speak a word of English, and we had no idea what our tickets said. We thought we would get dropped off in Katerini and then go to Dion from the same bus stop. That wasn't the case. Our bus left us at this grayhound station, and we had no idea where to go to catch our next bus. There were dozens of bus stops around the town, and we had no idea which one to go to. The locals directions were confusing, and we walked around in circles for over an hour trying to find the right bus stop. We finaly did find our bus, and did make it to Dion, but once again the driver didn't speak English, and we almost missed our stop.
My advise, make sure you know ahead of time what stop to go to when changes buses, and make sure you double check to see if you bought tickets for ALL buses or just one. Because the driver gave us 3 tickets stapled togethor, so I thought it was for ALL the buses, but it turned out it was only for one! I had no idea how much we payed for them either!
