If you find Toluca too calm, take the hour bus ride to Mexico City.
If you find Toluca too traditionally Mexican, just taxi to the southestern suburb of Metepec, and you will think you are in southern California with malls, multiplexes, big box stores, and luxury car dealerships.
If you find Toluca too stressful and modern, take a taxi or bus southwest, past the big prison, to Almoloya de Juarez. Walk around the sleepy town square and look at the church built on the grotto of water ojo de agua. Look for the magic line in the water.
You can get out of Toluca for a daytrip to the volcano El Nevado de Toluca but that might trigger altitude sickness in some, or the Zacango Zoo, or the spas at Ixtapan de la Sal, or Valle de Bravo.
