Mexico City

We were pleased to find a flight home via Mexico, rather than the more usual stopover in the US. It is one of Rachel's favourite countries, having studied here in 2001 and returned since, and nice to be there together and for Simon to get a feel for it. It was a gloriously sunny day and only slightly smoggy, which meant fantastic views of the enormous sprawling city and surrounding mountains as we came in to land.

It's hard to get your head round the scale of one of the world's biggest cities. We had a wonderful time exploring the centre for a few hours before our flight home.

Every other car isn't a Beetle any more as it used to be, they've stopped making them and there's been an influx of Chinese and Korean cars. It's still easy to spot the classic adopted Mexican vehicle though.

We headed for the Zocalo, the enormous central square, which was dominated by a temporary exhibition, due to open the next day.

The cathedral is a whopper by any standards.

Our final joint photo in Latin America

There is still a ramshackle charm to the central back streets. Mexico City first appears to be a very modern and clean city, easy to travel around by metro. It's got beautiful, historic buildings and shiny modern tower blocks, but the great thing is, you're only ever two corners from a real sense of a vibrant Latin America, such as this back street flea market.
