A guide on how to enjoy going to the zoo. Tips include bringing no children, walking, taking your time, and going early or staying late:
Many animals are more interesting at dawn and dusk, so the earlier or later you can arrange your visit, the better. If you ever find yourself in Singapore, don't miss the famous Night Safari. You haven't lived until you've felt your way along a jungle path in utter darkness, rounding a corner and spotting a pack of hyenas in a pool of light twenty yards away, with no apparent fence between you.
