One of my favorite quick trips of the last few months was Monaco. After surfacing from the train station, a couple of high-end German cars drove past but not long after, a small fleet of Lamborghinis ripped past us on one of the legs of the famous F1 street circuit. For most of the day, it was supercar after supercar.
If you’re into cars, you must check out the Cars Collection of HSH the Prince of Monaco. And be sure to walk up the hill to the Monte Carlo casino. If you want to make it past the lobby, you must have your passport on you. There are also excellent people and car-watching outside spots at nearby restaurants and coffee shops just out front.
