Actually, I did this entry before, National Zoo in Hulu Kelang.
This place is situated just 13 KM northeast of Kuala Lumpur, the zoo houses some 200 species of animals, birds and also reptiles. Spend the day observing tigers, lions, Sumatran rhinos and other wildlife or watch entertaining performances by orang utan, elephants and sea horse at scheduled hours.
Children and adults alike will enjoy the horse, camel, and elephants rides. Tram rides are an interesting way to explore the zoo. If you want to see the Zoo by Night, you can go to Malacca Zoo or Taiping (Perak) Zoo.
