Who would've thought cacti could be so much fun? With 7000 varieties of cacti and succulents, the Jardin Exotique is paradise for prickle-lovers. If 7000 cacti is about 6998 too many, the Jardin is still worth a visit for its spectacular views. The entry price also gets you into a cave complex packed full of stalagmites and stalactites, and the Musée d'Anthropologie Préhistorique, which tells the history of humanity through archaeological finds from the area.

This ain't your usual collection of dusty rocks and stuffed animals: the Musée National de Monaco is dedicated to dollies and their frightfully spooky siblings, automata. The Musée has everything from a dancing Josephine Baker robot to the Ken and Barbie owned by Princess Caroline to a gigantic 18th-century nativity scene packed full of little locals. Put your hair in pigtails and get on down.
