I am writing this post just to help people get to Taman Safari without shredding out heavy bucks on Taxi travel. I had my stay in Kristal Hotel in Chilandak Barat, Jakarta. If you happen to stay in the same hotel then this will be a complete guide for you.
Just outside the hotel you will get bus number 79 that will drop you to Lebak Bullus for 2000 rupiahs in about 20 minutes. From there you can get a Air Conditioned Bus for 10000 rupiah to Ciawi which is will take around 1-2 hours depending on the traffic. From Ciawi turn to the road going left and take a shared auto that will take you directly to Taman Safari in about 20-30 minutes and will ask you for only 3000 rupiahs.
This is the option that I used and I think was the best and the safest option that anyone can get. If you find a better and cheaper way...your comments are welcome to this post...
Hope you have a nice time at Taman Safari !!!!
