Yes, tourists can bring a drone to Bali and travel with it to Indonesia. Most travelers visit Bali with popular drones such as DJI Mini, DJI Air, or DJI Mavic series. There is no specific restriction preventing foreigners from bringing a drone into the country for recreational use.
However, you must follow airline safety rules for transporting lithium batteries and respect the Indonesian aviation regulations once you arrive. Always keep drone batteries in your carry-on luggage and never in checked baggage.
