It is forbidden to fly over temples unless to get the approval, but people are kind and can allow you to fly at a reasonable distance if you ask nicely. You can’t fly close to restricted areas such as airport, military camps etc… Finally, more and more hotels forbidden the use of drones to preserve the privacy of the guests, so think to ask the authorization of the management before to takeoff. In Bali, a lot of people come for peace, silent, and meditation, so please, respect everyone’s well-being 😉
