Educational trail
The "In the Footsteps of Giants" educational trail at Courtedoux brings the Jura's palaeontology and geology to life. At the end lies a famous site where 152-million-year-old traces of sauropods (herbivorous dinosaurs) can be seen. Some footprints are over a metre in diameter. Some small theropod (carnivorous dinosaur) footprints are also visible.
