Museo a Cielo Abierto
This "museum" is actually a winding walk past 20 official murals (and dozens of unofficial ones) by some of Chile's best painters. There's even one by the country's most famous artist, Roberto Matta. The path is not marked, there's no fixed route, and much of the signage has disappeared over the years. The point is to get lost in the city's history and culture.
