Lefkada is located on an active seismic zone and you should take that into account, if you plan to do free camping on the beach. Especially the beaches of the west coastline are surrounded by steep slopes and there could be landslides, even in case of a minor earthquake.
Toponymy in Greece is difficult.
1 More often than in any other country, the same name will apply to several locations.
2 If you look at several maps, even considering only Greece designed maps, you will notice that the same place can be named differently.
3 Even if the name written in Greek fonts is the same, it can be transcript in different ways, even by the Greek themselves.
4 Moreover, because of the declinations, the same name can be found with various endings.
5 Last but not least, foreign maps will, at least for some locations, give another transcript name.
6 Finally, the name found on the VT database can be one of the previous, or another one!
The Greek web site "The Guide to Lefkas" begins by : "Welcome to Lefkas, also known as Levkas, Leucade or Lefkada"* They have indeed forgotten Sainte Maure and Santa Maura and may be other names !
Corfou, Corfu, Kerkyra are the same place, etc…
Athina, Athinai, Athens, Athènes, Atene as well! Etc…
As a general advice, there are not many signs on the streets, sometimes you have to guess which direction you'll follow. Another problem is that kind of traffic tangle, but a pleasant one...
