Most people go to Interlaken where the 2 lakes of Thunersee and Brienzersee meet. But in reality the 2 towns at the other ends of the lakes have much more charm.
A perfectly preserved picturesque village with a cobblestone street leading up to the castle at the top of the rocky crag. At the bottom of the hill is a diary where all sorts of cheeses are available, obviously notwithstanding the local product, which comes in 5 stages of maturity.
More scenery. Castles. A beautiful lake. We stayed on a farm, should do that more often.
