In Xochimilco, on the outskirts of the city, is a superb collection of paintings by Frida Kahlo and the largest private collection of works by Diego Rivera. The museum was established by Olmedo, his lifelong model, patron, and onetime mistress. The lavish display of nearly 150 pieces from his cubist, post-cubist, and mural periods hangs in a magnificent 17th-century hacienda with lovely gardens. Concerts and entertainment for children are held on weekends, while gaggles of geese and strutting peacocks add to the clamor. This is also the place to see the strange Mexican hairless dog: Ms. Olmedo shares Rivera's passion for these creatures and keeps a few as pets on the grounds. There is a lovely small café in a glassed-in gazebo. The museum is reachable by public transportation; at the Tasqueña metro station, catch the light-rail to La Noria (not Xochimilco). As you exit the light-rail station, cross the street via the stairway bridge. Walk half a block on 20 de Noviembre until you come to a traffic intersection. Without crossing the street, turn left at this intersection and continue walking down this street (signs will read Antiguo Camino a Xochimilco or Av. Mexico) for two blocks.
