Begin your evening tour with pickup at your hotel in Monaco and drive east on the Basse Corniche road toward the Vista Palace Hotel. As the road climbs, you'll get better and better views overlooking the Mediterranean – passing the Medieval town of Eze on the way – until you arrive in Roquebrune-Cap-Martin and the Vista Palace Hotel perched on a hill. From there, the view down to an illuminated Monaco are splendid.
Back down in Monaco again, see the stately Prince's Palace all lit up against the night sky. This is the historic palace from which the Grimaldi family has ruled the principality since the 13th century. See the Monaco Cathedral (Saint Nicholas Cathedral) where Princess Grace and Prince Rainier are buried. Walk through the streets and squares around the palace and cathedral in the Old Town of Monaco-Ville, sometimes called 'Le Rocher' or 'The Rock.'
Drive into glitzy Monte Carlo and take a moonlit stroll through Casino Square. Check out the opulent casinos and luxury hotels, not to mention the well-heeled clientele in both. Enjoy some free time here to take a romantic walk, try your hand in one of the casinos or have dinner in one of the chic restaurants nearby (own expense).
Take another drive along the Basse Corniche to appreciate the views after the sun has gone down and, at the conclusion of your tour, get returned to your hotel in Monaco.
