Some estancias specialize in breeding horses and offer ideal conditions for travelers wanting the ultimate horseback riding vacation. Ranging from beginner to expert levels, these ranches usually offer guided trail rides, polo lessons, and a chance to ride along with the gauchos as they go about their daily ranch activities. There are even a few that will let small groups of guests take on roles almost to the point of being a gaucho for a week or more. At the other extreme, some ranches also have their own tack shops and will outfit a guest in gaucho apparel and equipment whether he or she ever rides a horse. Those estancias that cater more to serious riders tend to be located to the north and far south of Buenos Aires while dude ranches can be found on the outskirts of almost all major cities in Argentina. Other estancias, while offering horseback riding for guests, also have regularly scheduled events on site that demonstrate the unique skill of the estancia's gauchos. On these ranches, a visitor usually will see gauchos displaying their world-class horsemanship as they break a young horse or display showmanship of their considerable equestrian talents.
