This particular one was taken in Singapore Zoological gardens, which I visited with my wife and daughter during a recent trip. This zoo is fantastic - big, clean (you're in Singapore after all), a train is running all around if you get tired, and they even have a polar bear in there - not bad when outside temperature is 30 degrees+ and humidity probably over 80%
One of the highlights was actually to go and feed the giraffes - you make your way to a raised platform, buy a plate of cut veggies /fruits for 5 Singapore dollars (it's a donation), and wait your turn to get 2 or 3 giraffes popping their head over the platform's balustrade, and display a very curly tongue to grab some pieces of fruit - I'm sure they are well fed at any time, yet this must be a treat for them!
If you have a chance to get there, this is a highly recommended family activity - plus the photographer in you will be spoilt!
Thanks for your visit and ongoing support
