Edith was a delightful & knowledgable tour guide whose knowledge of Mexican history made our tour of Chapultepec Castle an excellent Day 1 overview for our first visit to CDMX. The castle grounds & 360 vista views of CDMX are stunning, but it was Edith’s enlightening overview of Mexico’s history that made this tour 5 star. I would suggest doing this tour first thing in the morning as the crowds build from midday onward.
