Champ de Mars Park is essentially Paris's front lawn, and what a lawn it is—with front-row seats to the Eiffel Tower! It's where you go to snap that "I swear I'm holding the tower" photo or to gaze up and ponder, "How many baguettes tall is that?"

Feel like sprawling out on the grass with a baguette and some fromage? This is your stage. Want to be entertained? The park's calendar is more packed than the Métro at rush hour, with everything from head-banging concerts to fancy markets that'll have you saying "Ooh la la!"

And let's not forget, it's a hop, skip, and a jump away from other must-sees, so your feet won't even have time to complain. Plus, it's soaked in history like a croissant in coffee—this place has seen more action than a Musketeer's sword! Oh, and for the sports fans, it's turning into the Olympic beach volleyball court. Sand, in Paris? Très chic! Plus wrestling and judo on the east end.
