Ah Paris, every corner is so picturesque! Climbing up to the top of Arc de Triomphe to see the sunset is always on top of my list when visiting Paris. One of my favorite moments was climbing up Notre Dame, probably my favorite view of Paris. So breathtaking, a must when you're in Paris. I would suggest looking up the times when it's open and also making sure you get there earlier as I waited an hour in line. Also, if you're 25 and under I believe entry is free to museums and certain attractions in Paris with valid passport or ID!
Many people have been asking where the colorful Paris in street is, it's Rue Cremieux in 12th arr. I would suggest going early so you don't have anyone else in your shot, a beautiful street in Paris lined with colorful homes. Pont Neuf is the bridge where I took a photo of the locks, another beautiful bridge in Paris it's hard to pick favorites! Also, when in Paris you have to go to Montmartre - my favorite area in Paris. Wander and get lost, you won't regret it. I'm hoping to make another visit this year and take my sister with me :) Hope you have a lovely weekend!
