In 1983, following his defection to the U.S., Béla Károlyi purchased 40 acres of the Sam Houston National Forest, where the camp is located. A year later, gymnastics facilities and cabins were built and the ranch was open for summer camp. After Mary Lou Retton won a gold medal at the 1984 Olympics the ranch's enrollment increased to 1,400 students. From 1986–89, the property expanded to 2,000 acres. The ranch had a state of the artwomen's artistic gymnastics facility as well as a dance room, medical room, office, rhythmic gym, trampoline and tumble gym and a sports acro gym. It also had athletes' and coaches' cabins, dining halls, meeting rooms, TV room and a cafeteria. The camp portion of the property was about. In 2001, the ranch, was designated by USA Gymnastics as the U.S. Women's National Gymnastics Training Center. In 2011, the Karolyi Ranch was recognized as a U.S. Olympic Training Site by the United States Olympic Committee. In January 2018, USA Gymnastics terminated its lease of the Karolyi Ranch during the sentencing phase of the trial of Dr. Larry Nassar, who was found guilty of numerous acts of sexual assault against young gymnasts, many of which took place at the facility, where parents were not allowed to be present. A lawsuit was filed against the Károlyis in 2016 alleging that they had known about and "turned a blind-eye to the sexual abuse". On January 25, 2018, the Ranch announced the permanent closure of the facility on its website. On January 30, 2018, the Texas Rangers took over the criminal investigation of the ranch.
National Team camps
National Team camps for the women's artistic program were held once a month at the ranch, attended by members of the women's national team and current elite gymnasts that the selectors considered good enough to attend. Different training models had been tried in the past but had been unsuccessful. Based on the former Soviet model, gymnasts used to live at national training centers. Later, they trained with local coaches closer to home and came together every four years to train as a national team. In 1999, USA Gymnastics settled on a "hybrid" approach combining these two training methods: Gymnasts trained with local coaches, but each month they and their coaches attended a four-day camp with Márta Károlyi. After the poor performance of the United States Olympic Team at the 2000 Sydney Olympics, the method of selecting athletes for competitions was also changed. In the past the six gymnasts with the top scores at the Olympic Trials went on to compete in the Olympics, but after 2000 the team was picked by Károlyi after a five-day training camp at the ranch. Kelli Hill, who coached Olympians Dominique Dawes and Elise Ray, spoke in favor of maintaining the old ranking system.
