It's so easy to visit Bora Bora on a budget! There are plenty of guesthouses for $50 a night, you can get around cheaply by bicycle, and there are affordable food trucks to help you save money on food!
Absolute best things to do in French Polynesia and islands to go to! Bora Bora and Tahiti are great, but have you heard of Rangiroa and Mo'orea? They're the new up and coming islands of French Polynesia, and also less-developed and less-costly!
