Continuing an age-old tradition, the Queen's Swan Marker and Swan Uppers take an annual census of the swans living along the Thames between Blackfriars and Abingdon.

Roar! Europe's biggest street party transforms west London into a hive of music, food and fun each August long holiday weekend. More than two million people boogie during this carnival, which Trinidadian immigrants launched after the 1950s race riots. Now only steel bands battle in this neighborhood, so chic that Julia Roberts and Hugh Grant canoodled here in the rom-com classic "Notting Hill."

This notable run starts off in Hyde Park and finishes up at the seaside city of Brighton. Entrants can drive cars only that pre-date 1905, meaning that the run is quite slow, usually at about 20 miles per hour through the busy streets of London. There are great observance points at various locations along the London portion of the run, and usually the day before the race there's an outstanding display of vintage autos along Regent Street.
