We had our flight at 4 am the next day thus we decided to spend this day in Mexico City and went to Xochimilco. These canals are all that is left of the lake on which Mexico City was built. Many people come here to enjoy a boat tour. Official price per hour is 350 MXN per boat, however, local people do all they can to charge tourists more (they tried to charge us 1000 MXN at first). Other boats will try to sell you overpriced souvenirs or ask money for listening to their songs. You can politely decline everything that is offered and just relax and enjoy the cruise. This place was also declared a World Heritage Site since 1987.
We spent our evening in a famous Cafe de Tacuba that started its operation in 1912!
