In the penultimate episode of this series, we take a bracing walk with ranger Kate Martin as she battles against howling winds and biting rain to the summit on Divis Mountain, 1,500 feet above Belfast. As we cross this wild landscape we’ll discover blanket bogs that are as dangerous as they are healing, ruins that hold the secret to 2,000 years of life and death, and awe-inspiring views of the city and hills beyond.
