Lugano has handsome castles, a laidback vibe and excellent ice cream. However, once you’ve had a quick taste of la vita bella, it’s time to return north, as the Grand Tour turns back to the mountains. This time, the first-class carriages of the Gotthard Panorama Express will deliver you from the Ticino to lush central Switzerland, via the engineering marvel that is the original Gotthard Tunnel, an ingenious system of spirals, loops and bridges that first opened in 1882. Popping out the other side, you’re delivered back into an alpine idyll, which continues all the way to lakeside Flüelen. Here, switch from railing to sailing, for an unhurried voyage across Lake Lucerne.
