Our App offers educational and entertaining age appropriate audio and video content about The Atmosphere, The Structure of the Earth and The Solar System. It is a collaborative work of scientists, writers, space artists and voice actors.

The X-TRAILS App can be enjoyed on its own or as a companion to our Solar System interpretive signs. Visitors to one of our installed trails can download the free App via a link on the Welcome Sign, choose an age appropriate Audio Guide and operate it by scanning QR codes printed on the interpretive signs using the app’s in built scanner .
