Destination guide
Mexico City: One of the world's great food and museum cities
Mexico City is a short, inexpensive flight from most of the US and delivers big-city culture at a fraction of European prices: Frida Kahlo's house, the Anthropology Museum, Teotihuacán's pyramids and a food scene from street tacos to world-ranked restaurants.
Best time to visit: October–April is dry with warm days and cool nights; November's Day of the Dead and March's jacaranda bloom are highlights. May is hot; June–September brings afternoon rains but lush parks and lower prices.
