Steeped in legend, Notre Dame is the literal and figurative heart of Paris. This masterpiece of Gothic architecture features spectacular stained glass windows, spooky gargoyles, and a bell named Emmanuel that weights a whopping 13 tons. Climb the towers to a vertigo-inducing height over Paris, or head underground to the archeological crypt to see ruins from the ancient Gallo-Roman town of Lutetia. Stay all day—Quasimodo would be proud.
Foss Distillery's Birkir birch schnapps and Bjork birch liqueur are the ways to go. The former works well in shot form, the latter mixed into cocktails. Buy both at Vínbúdin or at the Keflavik Airport.
