Dozens of estancias, or rural estates that were once the private getaways of wealthy families have opened their doors to the public. Many of these country hotels offer a dÃa de campo (country day) thatâs ideal for day-trippers. After breakfast visitors typically follow the estanciaâs resident gaucho into the fields for a morning horse ride. Then itâs back to the farmhouse for a barbecue and a quick hammock siesta before hitting the trails again.
