Carlyle E. Linder Equestrian Park is a city-operated public park located in Glendora, California, designed specifically for horseback riding, training, and exercise. Nestled in the foothills, the unstaffed open-space municipal grounds feature a dedicated dirt riding arena, a ring, and direct connectivity to scenic multi-use foothill trails. The park provides free community access daily, offering a gravel parking area accommodates horse trailers alongside public restroom facilities.
