Clueless ride - Clueless tour, first they pass through a shopping mall on the border of the countries Brazil/Argentina, with prices well above the market (despite offering a dollar exchange rate of 3.76, normal exchange rate was 5.08), then to enter the country it is necessary go through immigration (at least 40 minutes standing around waiting), then in the Argentine city puerto iguazu, there is a street full of bars and an alley with little shops selling olive oil, olives and sweets, nothing special, it's only worth it if you're going to buy wines, I was with prices well below the market. On the way back another stop at immigration, another 20 minutes of stopping. Tour that started at 5 pm and ended at 11 pm, expensive and not at all fun. I do not recommend. Do your research before you go.
