There are still wild places out there on our crowded planet. Through a series of personal journeys, Dan Richards explores the appeal of far-flung outposts in mountains, tundra, forests, oceans and deserts. Following a route from the Cairngorms of Scotland to the fire-watch lookouts of Washington State; from Iceland’s ‘Houses of Joy’ to the Utah desert; frozen ghost towns in Svalbard to shrines in Japan; Roald Dahl’s writing hut to a lighthouse in the North Atlantic, Richards explores landscapes which have inspired writers, artists and musicians, and asks: why are we drawn to wilderness? What can we do to protect them? And what does the future hold for outposts on the edge?
