London ranks alongside Tokyo, Oslo, Paris, Sydney and Zurich for most expensive global cities, so being able to sniff out free fun is a valuable skill. Thankfully, though, London has always maintained an egalitarian spirit, especially when it comes to free art and public spaces. (This is, after all, the city that made squatting cool.) No fewer than ten of Zone 1's major museums (including The Victoria & Albert and The British Museum) offer huge yearly line-ups of free exhibitions. Even with its pricey quarters, London is a city of the people, and visitors should be advised not to equate cheap with cheap when writing up their itinerary. In fact, sticking to the freebies could land you a more authentic experience than you'd ever imagine: When the warmer months settle in there tends to be a greater divide in the paid attractions the tourists will line up for, and the hidden freebies that the locals know to pounce on. Maybe you're in the mood for a meander, or to see what the conceptual artists are up to. Schedule your stay around these colorful activities and you could easily put that hard earned cash towards something different entirely: leveling up your accommodation? A cocktail worth its weight in platinum? We'll leave it in your savvy hands.
