The area south of Mayfair between Hyde Park and St James’s Park, was once a burial ground for lepers, but now is a simple expanse of meadows and light copses of trees. It doesn’t have much to offer except pastoral views, and most visitors find themselves crossing it instead of dawdling in it, although its springtime flower beds (which bloom brightest in Mar and Apr) are marvelous. Don’t sit in one of those picturesque striped deck chairs unless you’ve got a few bob to pay as rent.
