The highlight of our trip to Guatemala was an evening in Panajachel of Marimba music (complete with stories about the music) and seeing examples of the different Mayan outfits of the area around Lake Atitlan. For information on shows, you can ask at Toliman Excursions Travel Agency or Jose Pinguinos Restaurant (both on Avenida Santander in Panajachel). Miguel Tzul runs both businesses, and produces the shows upstairs from Jose Pinguinos.
