Buenos Aires, Argentina
NileGuide Expert tip:
Hit up the galleries earlier on in the evening to grab some tapas and champagne before they run out!
The twice-monthly Gallery Walks rotate neighborhoods, cycling through Buenos Aires' main art districts of Palermo, Retiro and Recoleta, and San Telmo. Galleries, cafes, bars, and art foundations open their doors for the late-night event that typically spills into the streets and becomes more of a block party than your average art gallery function.
