4 days · CDMX + Teotihuacán
Is Mexico City safe for a first-timer? In the neighborhoods this trip uses, yes. Roma, Condesa, the Centro, and Coyoacán are busy, walkable, and full of locals out late. Use registered taxis or a rideshare app after dark instead of hailing on the street, keep your phone out of your back pocket on the Metro, and you have handled 90 percent of it. This is a relaxed four days with one early morning that earns its keep.
Days 1-2: Mexico City core
Give the first two days to the center and the museums. The Museo Nacional de Antropología is the one unmissable stop, and it takes half a day on its own, so go when it opens and pace yourself. Balance it with the Centro Histórico, the Zócalo, and Bellas Artes, then slow down in the afternoons with a long cantina lunch. Eat at least one meal standing at a taco stand with a line; a friend who lives here would tell you the busy stall with high turnover is safer than a quiet tourist restaurant, because the food never sits.
Day 3: Coyoacán and south
Spend a day in Coyoacán, the leafy south end where Frida Kahlo’s Casa Azul sits. Book the Casa Azul online in advance, because walk-up tickets sell out most days. The plaza, the market, and the churros nearby make an easy afternoon. This is the day to keep loose and just walk.
Day 4: Teotihuacán
Drive north on the toll road, about an hour, and stay the night before near the site. The whole reason to overnight instead of day-tripping is to be at the gate when it opens, before the tour buses roll in and before the sun turns the open plain into an oven. Climb early, carry water and a hat, and you will have the Avenue of the Dead nearly to yourself for the first hour. If an early start does not appeal, be honest with yourself and just do this as a half-day from the city instead.
