The upper stretch of the Thames unites a string of lustrous riverside pearls -- Chiswick, Kew, Richmond, Putney -- taking in friendly streets, horticultural delights, regal magnificence, and Henry VIII's fiendish outdoor labyrinth at Hampton Court Palace. Achieving a noble hat-trick of homes, gardens, and parks, the neighborhoods dotted along the way are as proud of their village-y feel as of their stately history, with many a pleasing pub nestled at the water's edge. After the bustle of the West End, here the pace slackens delightfully, and it becomes easy to forget you're in a capital city.
