Assalamualaikum
Johor Zoo is located near the Sultan Abu Bakar Mosque in Johor Bahru. It's just a small zoo compared to Zoo Negara in Kuala Lumpur. The entrance fee is also much, much cheaper, which is only RM3 (at the time of my visit in 2009). Since it's quite small in size, there are not many animals kept there. However, I noticed that there are more bird species compared to other species. I did enjoy my visit there though and it was my first visit there.
