Indonesia is a big country. with many islands. and also many cultures and of course each island has a different language. Tariffs for each region in Indonesia vary. but on average everything is cheap.
You can also relax about security here. origin is not in the big cities. you have to go a little into the countryside and the village. there you will find natural beauty and heaven on earth. even if you have a wooden stick. and you stick it in the dirt of the street. then it can grow into a plant. Indonesia's soil is so fertile.

and I will recommend one example of tourism that can be very satisfying, but this area is known to be very friendly and cheap. for $1 usd you can be satisfied to go around this city or area by bus. the name of the area is DI Yogyakarta. Even with $1 usd it was enough to buy 3 meals. (3 servings of filling food/morning/midday/evening).
I can't even count the total number of famous tourist attractions in this Yogyakarta area. because it's too much. This is just an example of a few pictures.








it's just a few places. and there are many more beautiful places in Yogyakarta. And remember that Yogyakarta is only one of the regions in Indonesia. There are 34 regions/provinces in Indonesia. and each region has hundreds and maybe even more tourist spots. because some areas have many islands too.

but in yogyakarta alone has more than 16 temples (historical sites). and 2 of them have been recognized by UNESCO as world heritage sites, namely Prambanan and Borobudur temples
borobudur.
Prambanan.
