"Make a wish if you please, and toss a coin to help animals in need." All proceeds from our wishing waterfall go directly to aid conservation efforts around the world. Each year, the money collected from the wishing waterfall will go to a different conservation project. These conservation projects are voted on by the Greenville Zoo AAZK members. If you would like to make a donation then please visit our wishing waterfall by the South American exhibits at the zoo.
