Horse riding is the most popular outdoor activity in the Limousin region of France. The document outlines what horse riding entails, where someone can go to do it, and what equipment is needed. It recommends going to a horse club and forest about 10km west of Limoges, where one can ride inside an arena or outdoors. Proper riding attire includes trousers, boots, a helmet, and saddle, while horses require a bridle to guide them and a properly fitted saddle.
