Some views in Regent’s Park instantly transport you out into another world outside London. This is one of my favourites: the busy southern end of Queen Mary’s Gardens, with visitors moving between the rose garden and the Japanese garden, but pause for a moment and look across the nature reserve at the end of the lake, and here in front of you is a piece of the countryside. It’s especially evocative at the moment, with the magnolias in bloom, the dry reeds, and the twisted willow coming into leaf against a slate-grey sky.
