Leake Street

Most tourists wouldn't think that one of London's most vibrant art locales might be down a grimy alleyway round the corner from Waterloo station. But Leake Street does indeed offer up a mesmerising selection of just that – the most exciting street artists and underground performance artists. Part tunnel-shaped canvas, part theatre space, and part actual commuter footpath, Leake Street (also known as "Banksy Alley") has been twice home to the Cans Festival, where the most high-profile graffiti artists across the globe meet to display their skill. It's a must-visit for anyone keen on getting beneath the city's surface – literally.
