I now consider the Sacre Couer to be a 'we need to see it every time we're in Paris' areas. And don't stay on the ground... CLIMB UP! The walk to the top is a MUST! Don't pay to see the catacombs... what a dissapointment... what you're paying to see is the basement! But the climb up and down is so much fun, the 360 view is spectacular and you really appreciate how enormous Paris really is, and on the way back down there is a gargoyle who you have to get out of his way or he'll bite your leg...lots of good fun photo opps here! Oh, and while you're inside the chapel, listen for who we call the "sprinkler people." Every time a person takes a photo or opens their mouth to speak, there are staff right there to loudly proclaim "Tsk Tsk Tsk, Monsieur, silence s'il vous plait!" drowning out your quiet conversation. We had to leave because our uncontrolled giggling over these hypocritical staff's directions really got to us! And follow the tourists over to the shops and cafes just to the west... fun and great photo opps here too!
