The Kalopanayiotis funicular
Kalopanayiotis is steep enough that, traditionally, it could only be negotiated by donkey. (Hopefully not partaking of the sulphur waters and suffering from diarrhoea.)
Now, there is a funicular to service the locals’ needs, and even though it costs a euro return, the locals use it plenty.
And since I never got around to using the Lycabettus funicular while I was in Athens, of course I sang The Funicular Song here. “Funiculi Funicula, Funiculi Funicula!”
