Fodor's Expert Review Bosque de Chapultepec

This 1,600-acre green space, literally translated as Chapultepec Forest, draws hordes of families on weekend outings, along with cyclists, joggers, and horseback riders into its three sections, which are divided from east to west by major roads. The first section is the oldest and the most frequented, as it is closest to the city center and home to many museums and other attractions. The second section is much quieter, with plenty of space for recreational activities, while the third section is largely undeveloped and generally functions as an ecological reserve.

At the park's principal entrance, the Monumento a los Niños Héroes (Monument to the Boy Heroes) commemorates the young cadets who, it is said, wrapped themselves in the Mexican flag and jumped to their deaths rather than surrender during the U.S. invasion of 1847. To Mexicans, that war is still a troubling symbol of their neighbor's aggression: it cost Mexico almost half its territory—the present states of Texas, California, Arizona, New Mexico, and Nevada.

Other sights in the first section of Bosque de Chapultepec include a castle, three small boating lakes, a botanical garden, and the Casa del Lago cultural center. You'll also find Los Pinos, the ex-residential palace of the president of Mexico, which is now open to the public for the first time thanks to Mexico's current president, Andrés Manuel López Obrador.
