Bastille Day Parade - France
France's national holiday commemorates the storming of the Bastille at the start of the French Revolution. Crowds line the Champs-Elysées for a military parade led by the President, and Parisians party until dawn as fireworks explode over the Trocadéro.
The evening before the big day is spent dancing in the Bastille square and at numerous balls that are organised around the city. Worth a look-in are the many parties held by the fire service in their stations, at which the fire-fighters themselves are usually the star attraction (their uniforms providing a lure for the ladies).
There is also a big outdoor Gay Ball if you fancy something more boisterous. If that doesn't take your fancy, try sitting down to the Incredible Picnic, one of the largest in the world, taking place in some 20 of France's departments.
