I had wanted to visit the pyramids at Teotihuacan, but traveling to the site is a bit difficult if you choose to go by yourself. As luck would have it, I stumbled upon a hotel, Hotel Estoril, that books tours for tourists. They had a one-day trip to the pyramids with a couple of other stops along the way. I paid my deposit and left, planning to embark on the tour the following day. The price of the tour was 330 pesos, which includes the price of tickets for the sites.
The following morning I was picked up by a van and brought to a holding area. This is where all of the tours meet up and are sorted into the correct group. At this point they asked for the rest of the money. There was a disagreement about how much the tour costs, and I ended up paying more for the tour than originally agreed upon. If you don't speak Spanish fluently, be ready for this type of occurrence. I decided to stop arguing and just enjoy the day as the difference was only $5US.
We met our tour guide and driver, Ramone, and set out. All of the tour guides are Spanish and English speaking. As we drove out of the city, Ramone would tell us historical tidbits about the statues and sites that we were passing. Our first major stop was at the la Basilica de Gaudaloupe, Mexico's religious center. For more information see my entry on Basilica de Gaudaloupe. Ramone then brought us to an obsidian factory where they demonstrate the use of indigenous plants for dyes and the art of obsidian sculpture by artisans on premises.
Beware before being herded into the store on site, as they will try and ply you with some liquor. They have samples of different tequilas, and then they will try and pressure you into buying a lot of their merchandise. I had the feeling of a stereotypical used car salesman when one of the sales women made her way over to me. You can end up spending a lot of money here if not careful. Most of the merchandise can be found in the city for less. The final stop is at the Teotihuacan. For more information, see my entry on Teotihuacan.
When the tour is over, you will be dropped back off at your accommodations.
I would recommend this tour as a means to get to the locations you want to visit, if you don't have a car. Otherwise, I would suggest just venturing out on your own.
