The event has been held every August Bank Holiday since 1966
Over one million people are expected to throng the streets of west London for the Notting Hill Carnival.
The event, taking place over the Bank Holiday weekend on August 29 and 30, is the largest festival celebration of its kind in Europe.
Here, you'll find background and essential information plus some tips on how to get the most out of the occasion.
It's in west London then, but where exactly?
Basically, the bit between Bayswater Road and Notting Hill Gate going north to Harrow Road and Maida Vale.
The parade route follows three sides of a rectangle of streets bounded by the Great Western Road and Ladbroke Grove to the west.
In between lie garden squares, stucco terraces and Portobello Road with its world famous market; adjacent, by Acklam Road, is carnival's main safety zone with first aid points.

What's the timetable across the weekend?
Carnival starts at 9am on Sunday, Kids' Day, when the costume prizes are awarded. The main parade takes place on Bank Holiday Monday from 9.30am. Both days end at 8.30pm.
Saturday's Panorama event - back in original venue Horniman's Pleasance Park in Kensal Green due to funding cuts - can sometimes be eclipsed; it's when the UK's top steel bands compete against each other for the title of National Champions of Steel.
What can I expect to see?
A mix of Caribbean flamboyance and London street chic: costumes boasting feather plumes, sequins and tassels; astonishingly ornate floats; and hundreds of food stalls lining the streets.
Be prepared for what Diane Abbott MP describes as 'a wall of sound', augmented by near-incessant whistle blowing, the traditional steel drum bands and up to 40 static sound systems playing soca, calypso, reggae, R&B, funk, house, dub and more.
Why the emphasis on costumes?
It's a party and everyone likes a bit of dress-up, carnival's many revellers included.
Costume also provides a link with the past when the abolition of slavery brought new freedoms to the Caribbean, enacted in mas, or masquerade, parades that mimicked the European fashions of former slave masters - even down to the wearing of white masks or whitening the face with flour.
Today, mas paraders such as Harlesden's Mahogany Carnival Mas believe costume to be the essence of carnival and spend many months preparing for the event - no mean feat given the ambitious floats and intricate outfits on show.
Themes for this year include 'Inferno' by Newham-based youth group Youthology Carnival Mas Band and the stilt-walking Masquerade 2000 with 'The Gift'.
What's the downside to carnival?
Strangely, not rip-off prices for food and drink in the main.

Carnival round-up with Dotun Adebayo 8-10pm on Monday
Elsewhere, take your pick from crowd-jostling reminiscent of the Boxing Day sales along Oxford Street; people variously off their faces on drink and drugs; theft; an undercurrent of violence as day stretches into night.
But, says Chief Superintendent Mick Johnson of the Territorial Support Group:
"It's important to remember that crime rates do remain relatively low at carnival, given the thousands of people who attend."
So I'll still be able to enjoy myself?
Definitely. Carnival is an expression of community solidarity. People talk to strangers. They also meet friends here and make new ones.
Any quick tips while we're here?
Go with the flow - and the crowds - on the day. Watch the parades till you've had enough, then let your ears take you to one of the sound systems for that instant, dancing in the street-style vibe.
Retire to the fringes for a respite from the noise and heat with some authentic Caribbean fare, such as rice and peas and rum punch. Alternatively, drink water. Above all, come early and leave early. The carnival website has more on
how to stay safe.
