Dunia Fantasi a.k.a DuFan is an amusement park in Jakarta. It is part of Taman Impian Jaya Ancol (or just "Ancol" for short), a resort destination in north Jakarta which houses a number of attractions among others SeaWorld and Atlantis Water Adventures. Its large area is often used to host events such as Java Rockin' Land (an annual rock festival).
DuFan has the typical rides such as the merry-go-round, ferris wheel and roller coaster.
For a guide on the rides, I found this blog post quite useful. (Note though that since it was written in 2009, it hasn't included DuFan's newest ride: Hysteria). Please check it out: Guide to Dunia Fantasi
Since I don't have a strong stomach, I only went on the "easy" rides and avoided the challenging ones such as the Tornado where you are twist and turned while dangling in the air.
Even a few of the boys looked sick after going on it
But I was intrigued with Hysteria after seeing it didn't involve any spinning around, just a few "freefalls". So...I gathered the courage and went on it and well...words can't explain, you need to try it yourself ;)
