As of recently, visitors to the Amsterdam zoo Artis are invited not only to visit the elephants, but to observe them with other senses than just the eyes. Two years ago, an educational route called The Elephant Trail was laid out around the elephant enclosure; the route consists of five installations designed by Maarten van Kesteren.

These brass instruments demonstrate the sensory world of elephants and allow visitors to experience this world. Visitors are invited to listen to the animals and discover what they mean by certain sounds. They can also experience sight, smell, temperature and touch. Taste, however, is the only sense that could not (yet) be realized.
