The Arabian Horse Association is a member organization that is made up of 18 Regions throughout the United States and Canada. The 18 Regional boundaries were designated by horse population. Some Regions encompass many States. Due to the number of horses in our area, Region One covers both Southern California and Hawaii. Region One itself is made up of nine clubs that are designated by both location and interests. Some of the clubs are involved with Racing, some with Competitive Trail and Endurance and other with Horse Showing. Region One offers many ways for both the horse owner and equestrian lover to enjoy this magnificent breed.
