Where is Bora Bora ?

Bora Bora is part of the French Polynesia. The French Polynesia is located in the Pacific Ocean. You can say it's between Chile and Australia. Since that's quite a big place here is a picture to see where exactly the French Polynesia is. 

French Polynesia is composed of 118 islands; the most important one is Tahiti where the capital Papeete is located. All international flight gets first to Papeete and from there you can take a ferry or a plane to the other islands. 

They speak French; however as they basically live from tourism they all speak English as well. I was also really pleased to find out that there are a lot of people who speak Spanish, so if you only speak Spanish don't worry there is a lot of people that speak Spanish too.
