The $20 Million International Orangutan Center at the Indianapolis Zoo will open in 2014 and is arguably “the best zoo habitat for orangutans anywhere in the world" according to experts. The exhibit will sit on 4 acres in the heart of the Indianapolis Zoo. One of the features of the design is an aerial cable ride with enclosed gondolas 40 feet off the ground, that will allow humans to get within 30 feet of the orangutans' Hutan Trail, a highway of cables and bridges that the primates use to leave the atrium and move to other parts of the exhibit.
