August Bank Holiday weekend means it's time for Notting Hill Carnival, Europe's biggest street party. It's a colourful, vibrant celebration of London's Caribbean communities and culture; over two million revellers come for the elaborate costumes, pumping sound systems and good vibes - plus of course the Carnival wouldn't be complete without Caribbean drinks and eats as well as beats. Keep track of all the action with the free official Notting Hill Carnival app, which has a live, GPS-tracked map showing all of the floats and their locations, plus maps showing all food vendors, toilets, transport links and sound systems. Post in-app to meet fellow carnival-goers and vote for your favourite band at Panorama. Planning on joining in the fun? We have a handy guide with all you need to get the most out of Notting Hill Carnival.
