A heated outdoor pool! 50 metres long! Open all year, all weather, in one of London’s sceniest parks! The London Fields lot were rightly smug when this long-dormant, functionally designed lido in the park’s northwest corner was finally resurrected in 2007 and heated to 25oC, just to add to their smugness about being in Hipster Central. Plus there are three cafe’s servicing the swimmers (and on summer weekends, there needs to be, when the place turns into one big posing pageant). But London Fields Lido is perhaps most atmospheric in winter, in the rain, in solitude, with steam rising off the water, when you can almost imagine how it was in 1932 before the cool kids came along.
