Some cities are best explored one watering hole at a time. These are my handpicked bar crawls across the world, built around neighbourhoods where the drinking scene is as much a part of the destination as its sights, streets and food. From sunset rooftops and legendary cocktail rooms to hidden bars, craft beer taprooms, neighbourhood pubs, live-music haunts and gloriously eccentric drinking dens, each crawl strings together a handful of places worth knowing and, more importantly, makes getting from one to the next part of the adventure. Come for the first drink, follow the trail, and see where the night takes you.
