Le Cascine is the lung Florence forgets it has — a long green wedge along the Arno west of the centre, once the Medici dukes' hunting and dairy estate and now the city's running, picnicking, market-day park. It's nearly three kilometres end to end, so this is a walk you let unspool rather than tick off.
Best in the morning, when the avenues belong to runners and the light comes through the planes in bars. From the T1 tram at the western end, take the wide central avenue east, then drop to the Arno path along the river side — quieter, with the rowing crews out. Back up to find the Monument to the Indian Prince, the marble memorial to a young maharaja cremated here in 1870, which is exactly as unexpected as it sounds.
Carry on to the eastern clearing — the Tuesday market ground, vast and empty any other day — and the little pyramid-roofed icehouse nearby. The park tapers to Ponte alla Vittoria; end on a bench by the river and take the T1 back.
