Slovenia's capital and largest city is one of Europe's greenest and most liveable capitals; it was the European Commission's Green Capital of Europe in 2016. Car traffic is restricted in the centre, leaving the leafy banks of the emerald-green Ljubljanica River, which flows through the city's heart, free for pedestrians and cyclists. In summer, cafes set up terrace seating along the river; it almost feels like a nightly street party.
