Experience Xochimilco, a marine ecological reserve and UNESCO World Heritage site, located just south of Mexico City. Step aboard a ‘trajinera,’ a colorful flat-bottomed boat, and drift through waterways dotted with floating gardens of flowers. Learn from an informative guide how this former agricultural canal network once fed the Aztec capital that lined the shores of Lake Xochimilco. Then, stroll through the National University of Mexico on a brief tour, where you’ll see an outdoor art gallery and a bullfighting ring. Hotel transport included.
