  description: Iztapa is Guatemala's off-the-beaten-path option—a fishing village better known for world-class sailfish than surf, where an uncrowded beach break rewards those willing to venture away from the mainstream. The wave receives the same south swells as neighboring spots but draws virtually no crowds, offering the rare experience of empty lineups in Central America. The fishing town atmosphere provides an authentic glimpse of Guatemalan coastal life, while river mouth sandbars create shifting peaks that change with the seasons. For adventurous travelers seeking solitude, Iztapa delivers.
