Xochimilco is an incredibly scenic area in the south of Mexico City, just an hour south from Mexico City’s historical centre. On this tour you can drift in a flat-bottomed boat through the lovely floating gardens of Xochimilco and marvel at the once-enormous agrarian canal system that fed the Aztec capital. In Aztec times, with prime farmland being scarce, the Indians developed a system of floating reed mats loaded with soil and used them as gardens. It is now your chance to experience this wonder that took place so long ago! Though Xochimilco was declared a UNESCO World Heritage site in 1987, with environmental degradation, slow urbanization and dropping water tables, what is left of the canals is fast disappearing.
