Trooping of the Colors is another annual event in Bangkok that falls during December and is quite spectacular and worth catching if your'e in town during this time. The event replicates the British army ceremony of the same name, and features the air force, navy, army, and the royal guards all donning incredibly colorful uniforms, high plumed hats, and getting in full regalia to pledge allegiance to the royalty and country. There's a brass band playing, a lot of protocol and fanfare, and there are some excellent photo opportunities. The surroundings out in front of the Dusit Palace are also pretty regal, and thousands of locals attend to check out the proceedings, so it has the atmosphere of a real festival.
