Well, the fisrt thing you need is a Syrian via. There is no direct border between Lebanon & Turkey.
The other thread (post #4) has information on transport which seems roughly correct.
Lebanon issues visas on arrival to most westerers including Swiss passport holders. citizens. Theoretically they are supposed to be free, however people are almost always still charged at land borders (roughly 20-30 €).

Swiss citizens do not need a visa for Turkey. The Syrian visa is best obtained in advance at an embassy in your home country.

If you take the Fergün ferry from Mersin to Tripoli (if it is still running), you need no Syrian visa, of course. Otherwise get it from the Consulat général de la République Arabe Syrienne, Rue de Lausanne 72, 1202 Genève.
