Hi Sara! Personally I would do the visa online, that way it’s sorted when you arrive.

It depends how soon you’re traveling though, because the Indonesian government is talking about possibly allowing visa free travel again for 20 countries, including the USA. There hasn’t been an official decision about it yet, but hopefully soon. Before covid, you could visit Indonesia for 30 days without a visa, and without any payment.

For the sarong, it’s supposed to be included in your ticket price at Lempuyang Temple, but if it’s not then you can rent one there for cheap (shouldn’t cost more than 20k Rupiah). If you plan to visit several temples, you can buy a cheap sarong at one of the markets in Bali and keep using it later. That’s what I did.

Is there a particular long skirt or sarong we need to wear (and for men also)? I think they charge separately for sarongs now .
Thank you in advance!
