Try going for a stroll in much of Guatemala City: It is a pedestrian’s nightmare.

Motorcycles speed down crowded sidewalks. Rifle-grasping guards squint at each passerby, sizing up potential assailants. Smoke-belching buses barrel through stop signs.

But tucked within the chaotic capital’s crazy-quilt sprawl, there is a dreamlike haven where none of that exists.

In the City of Cayalá, a utopian domain created by one of Guatemala’s richest families, the streets are quiet and orderly, the stores are upscale and the homes attainable — if only to families from the country’s small, moneyed elite, or foreigners, like the American diplomats stationed at the huge newly built United States embassy nearby.

Evoking the feel of a serene Mediterranean town, Cayalá features milky white buildings with red-tile roofs, a colossal civic hall with Tuscan columns, cafes and high-priced restaurants, colonnade-lined plazas and walkable, stone-paved boulevards. All of this is open to the public — except for the gated sections where about 2,000 families live.

“In 20 years, Cayalá will be just like La Rambla,” said Andrés García Manzo, a restaurateur who lives in one of Cayalá’s secluded villas, drawing a comparison to Barcelona’s legendary pedestrian-friendly promenade. “You can walk everywhere here in peace.”

But critics say it is largely a playground for the well-off, hard to reach by public transit, environmentally devastating and has attracted significant investment even as other parts of crime-ridden Guatemala City fall into decay.
