At the foot of the Jura mountains, with a view of the Alps across its vineyard-ringed lake, is the university town of Neuchâtel. Its distinctive sandstone architecture led the writer Alexandre Dumas to describe this French-speaking city as resembling 'an immense toy-city carved out of butter.'
It felt like a great place to call home during the month I spent there: twilight at 10 p.m., breezes off the lake, nursing an espresso (or a glass of the local white wine) in the shade of Renaissance façades.
The university attracts students from all over during its summer language programs; my classmates came from Italy, Poland, the Canary Islands, Canada, and the German-speaking regions of Switzerland.
Hourly trains run to Neuchâtel ('Neuenburg' in German) from both Geneva and Zürich--the trip lasts about an hour and a half. Lausanne and Bern are only 40 minutes away by train. And yes, you can set your watch by those trains...
