If you want to explore Brazilian art and perhaps buy some locally made pieces of art for yourself or your loved ones, be sure to visit Embu das Artes. Every weekend a fair is held here where various pieces of art, as well as e.g. antiques, jewellery or textiles, are sold. It is an ideal destination for a trip from e.g. Sao Paulo. Besides the open-air art fair, you can also visit museums located here or taste the local cuisine in one of the many restaurants or cafés in the city center.
