Hidden away in the heart of the Chapultepec forest, this museum can be difficult to find but is worth the time. Bright and spacious, it has a collection of works by famed Oaxacan painter Rufino Tamayo (but they aren't always on display). Temporary exhibits include both important international art and lesser-known works by Mexican artists. Most work leans toward the modernist and cutting-edge. Daily except Monday 10 am-6 pm. M$15 adults. Free on Sunday. In Chapultepec Park, at the corner of Paseo de la Reforma and Gandhi (Chapultepec metro station), Mexico City. Phone 5286-6519 or 5286-6529. http://www.museotamayo.org.
