As the longest day arrives in the northern hemisphere, Jeremy, Nadia and Keir ponder our obsession with the great outdoors. How did parks become political? Why do we seek out the strenuous discomforts of hiking, camping and cold water? And what does Jem have against music festivals?

They look back on a century of changing attitudes to the outdoors, from radical Edwardian cyclists and the woo-woo ways of the Kindred of the Kibbo Kift to the modern obsession with lidos and wild swimming. Plus, pastoral music from Peter Gabriel, Arthur Russell and Bow Wow Wow.
