If you want the museum at its quietest, weekday mornings are your best bet. By arriving early, you’ll avoid school groups and tour crowds, giving you space to linger inside the dimly lit halls of the Aztec and Maya rooms — some of the most visited galleries in the museum. Avoid weekends if you're sensitive to crowds, as it's a popular stop for both tourists and locals. While the museum is open year-round, Mexico City’s dry season (November to April) makes for a more pleasant walk through Chapultepec Park, which leads to the museum.
