Monte Carlo is a city in Monaco. In A Grimm Warning, Conner, Bree and Granny Pearl travel here from London to visit the Lumière des Etoiles casino and retrieve the magic panpipe to open a portal to the Land of Stories.
"The city was gorgeous. A cluster of colorful hotels, resorts, and residences grew down the Monégasque hills and streched along the ocean side. The salty smell of the ocean was all around them. A bay a little ways along the shoreline was home to hundreds of boats and yachts that bobbed in the bluest water Conner had ever seen."
They initially have a bit of trouble finding the place, as there are so many casinos in Monte Carlo, but Granny Pearl eventually finds it.
