Starting the final part of her journey on the island of Anglesey, Carol indulges in a teenage dream at RAF Valley testing her pilot skills on their cutting edge fast-jet simulator. She meets Dani Robertson, north Wales's very own Dark Skies Officer, who works to safeguard Snowdonia against light pollution, meets former Paralympian Mark Williams whose award-winning start up produces life-changing prosthetic leg covers for amputees, and finishes her journey with a eco-friendly ride up Wales's highest peak on one of the Snowdon mountain railway's brand new electric hybrid locomotives.
