"This is the most well-known museum in all of Argentina—and for good reason. Located in the upscale Recoleta neighborhood, the fine arts museum is home to a staggering collection of 19th-century European art, holdings that include over 700 major works by artists like Goya, Van Gogh, and Toulouse Lautrec. There’s a lot to see, so it makes sense to tackle the museum strategically, and with a guide. Artist Germán Warszatska leads free English tours on Tuesday, Wednesdays, and Fridays at 1 p.m.; though if you decide to skip the tour, head straight for the 19th-century European art wing on the first floor, widely considered the most important collection in South America." - Allie Lazar
