New to Swiss

Presumably you want to drive and have the benefit of being in central europe

Blach forest / easy to get to very pretty and good food.

Italian lakes / Bellagio but good luck getting somewhere to stay and if you intend to go through tunnel time it to be very early or go over the pass.

Bourgogne. Vineyards trip / take or rent bikes.

If you just arrived / try Switzerland.

nuremberg ok, and in understand the philosophy of having a quick peek and deciding to come back later for a better visit, but are you serious? you just spend time in the car and see nothing like this. i would just do prague in 4 days including trips.

Seconding an earlier post, stay in Switzerland.

Boat tour on the Zurich lake, go to the Rhinefalls in Neuhausen, Stein am Rhein, Bodensee, Luzern.

So many lovely things to see here. And if you want to go abroad and not drive too long, Black Forest, Colmar
