3 musts u need to know before arriving in Bali

First, pay the Bali tourist tax at this website.

Third, purchase and obtain your B1 e-visa through the official site. Here, when you receive your visa, it'll have a QR code on it, and then at the E gate, you scan your visa QR code, then you scan your passport

Second, fill out the online customs declaration form here. These will both be linked to your passport, so you won't have to do them at the airport.
