4th edition 2018. Mexico City is the largest city in the Western Hemisphere, let alone in Mexico, and is one of the most populous cities on earth. Regardless, this has been a popular ITMB map for quite a few years. With this edition, we are reversing the order of the title from its previous format, although the map coverage remains the same, with just the title reversed. The map is double-sided. The city side concentrates on the core of the city, with insets covering the university area and the rapid transit routes. The city map covers from Chapultepec Park east to the TAPO bus terminal and from Garibaldi Circle south to the TAP bus terminus, with special attention given to the Centro area and the Paseo de la Reforma. When we were last in the city, we took the two-hour bus tour from the Zocolo, a great way to spend a sunny day, hopping off at various sites! The other side covers Mexico from Guadalajara to Oaxaca and from San Miguel de Allende south to Acapulco. This covers the heartland of Mexico and assists travellers making regional trips from the city to nearby cities, such as Puebla, Vera Cruz, or Cuernavaca. Mexico City scale 1:12.500/Mexico Central 1:1.200.000.
