Many travelers flying into Mexico have connecting flights in Mexico City. The majority of them are anxious to get on another plane to their final destination as quickly as possible, and never see more of Mexico City than the Benito Juarez International Airport and what they can glimpse out of the plane window.

Admittedly, everything in Mexico City is on a grand scale. With its 680 years of history; urban sprawl that covers over 1500 square miles; and population hovering around 20 million, the city can be intimidating, but those who do venture into the nation's capital may be pleasantly surprised by all the city has to offer.

If you'll be flying into Mexico City, consider spending a few days before continuing on to your final destination. Some time spent exploring this city can be a great complement to your trip. This list of the Mexico City sights you shouldn't miss will help you make the most of your time.

Today is Groundhog Day in the United States, and folks concerned about the weather of the coming weeks will be looking to see if Punxsutawney Phil sees his shadow or not, but in Mexico, this is Día de la Candelari­a (Candlemas), a religious holiday that marks the end of the Christmas season in the church calendar. On this day folks dress up figures of the baby Jesus and take them to the church to be blessed. It's also a time to get together with friends and family to eat tamales - provided by whoever got the baby Jesus figurine in the Kings Day bread. Read more about Día de la Candelaria, and see our Candlemas photo gallery.

As yet Canadian citizens have not been required to present a passport when traveling to Mexico, although since January 2007 it has been required for entry to the United States. As of March 1st that's going to change. According to the passport Canada website:

"As of March 1st, 2010, all Canadian citizens will need a valid passport to enter Mexico. Canadian citizens without a valid passport will not be allowed entry into Mexico and will be returned to Canada."

So if you're planning a trip to Mexico, don't delay - get a passport now!
