There are few images more romantic than lanterns floating down the river in Hoi An. The Full Moon Festival each month draws hundreds of tourists to the UNESCO World Heritage-listed old town for what seems to be a quintessential experience in Vietnam. In fact, it’s so popular that the “festival” is no longer limited to the date of the full moon. You can find vendors selling lanterns to float on the river every single night in Hoi An. As I was preparing for my RTW trip, a blog post on Getting Stamped seeded my mind with questions. Is the Full Moon Festival an authentic cultural experience, or just a gimmick for tourists? More importantly, what happens to the hundreds of candles and paper lanterns that float down the river daily?
