We went to PEK last year and we visited El Djem via louage and back via train, very easy once you manager to find the louage station in Sousse! We also went to Monastir, got a taxi out and came back on the metro.
Thinking about where to visit this time, I'm thinking Sidi Bou Said but when we went to El Djem we couldn't find a louage to get back towards Sousse so am a bit worried about getting back again from Sidi Bou Said! Anyone done this, or know an alternative way to get back if louage is not an option?
Also, where would seasoned travellers suggest we visit this way?
