Mexico works as several separate trips: Mexico City with its museums and the pyramids at Teotihuacan nearby, the Yucatan peninsula with Mayan sites and Caribbean beaches, and the Pacific coast with a different climate and character. Domestic flights connect them; overland travel between regions takes days.
The guides here cover Mexico City and Mexico overall. The dry season runs roughly November to April, and hurricane season affects both coasts from June through November. Altitude matters in the capital — it sits above 2,200 metres, and arrivals often feel it. Archaeological sites open early and close mid-afternoon, which shapes any day built around them.
