The Paso Fino is a naturally gaited light horse breed dating back to horses imported to the Caribbean from Spain. Pasos are prized for their smooth, natural, four-beat, lateral ambling gait; they are used in many disciplines, but are especially popular for trail riding. In the United States two main groups of horses are popularly called "Paso Fino": One, also known as the Paso Fino Puro Puertorriqueño, originated in Puerto Rico.[1]: 331 The other, often called the Colombian Paso Fino or Colombian Criollo Horse, developed in Colombia. Though from similar Spanish ancestors, the two groups developed independently of one another in their home nations.
