First the hot air balloon is a must! Sunrise, misted temples, numerous fellow balloonists fill the skies. The on site touring guide, Carlo B. was trained in history (see his profile) and led a highly educational walk-ing tour, complete with a moon pyramid ascension. He then took us to La Gruta, a massive cave/ restaurant with excellent breakfast brunch options reflecting multiple Mexican food types. Placing a lit candle in the cave after the meal symbolizes rebirth, renewal and shedding of negative energy. Our guide made all this process smooth, efficient and understandable. Learning of the Teotihuacan culture of 500 years duration placed a new perspective in our lives that we will continue to process for some time.
