With its plains, valleys and rocky peaks, France's central Auvergne region has something of the Wild West about it. It's a paradise for horse riders, be they beginners, old hands or even celebrities like French actor Thierry Lhermitte. He says the sport allows him to relax and commune with nature. More than 13,000 horse riders come here to make the most of this little slice of America nestled in rural France. We take you on an equestrian tour of the region.
