Landmarks worth the trip on their ownAntigua Guatemala and the Central Park and Cathedral are the sights most visitors build their first day around, and both reward an unhurried visit rather than a rushed photo stop.
A different pace of daily lifeWandering through Chichicastenango Market or the ruins at Tikal (via a short domestic flight) gives a better sense of Guatemala City than any single landmark — it's where the everyday rhythm of the city actually shows.
Lake AtitlánOne of the more memorable stops for first-time visitors, and easy to reach from most central hotels.
A natural base for exploring furtherGood regional transport links make Guatemala City a sensible starting point if you're planning to see more of Guatemala while you're there.
