Restless for a new adventure, travel writer Simon Parker decided to cycle through all 15 of the UK’s national parks. His days within the parks, from Dartmoor to Cairngorms, via Yorkshire Dales and The Broads, could be idyllic or enraging. He explored wild moors and mountain tops, got stuck in plenty of holiday traffic, developed an injury, walked where the bike wouldn’t go, accepted pints and campsite pitches, and talked to everyone he met. These conversations provided Parker with a revealing perspective on the British and the wild-ish landscapes we love.
