One of my favorite places we visited in Indonesia was the pond at Dusun Bambu in Lembang, with little huts around it. My impression was that you could eat lunch in those huts. I don’t know if you could camp overnight there.
There’s two things Indonesian’s can out-do Americans at, in my humble opinion. Malls and restaurants. Here’s a few places we ate at near Bandung on Java.
My wife is from Indonesia and we went to visit her parents this summer on the island of Java. Last time I visited a few years ago I got healthy (or unhealthy) doses of dirty, polluted streets and glitzy malls. (Their malls make ours look like a tree house, but our shopping centers make their hole-in-the-wall shops look like mouse holes.)
