Welcome to Big Rock Ranch! We are located in the picturesque Santa Susana Mountains of Ventura County California. Our closest city is Simi Valley, home of the Ronald Reagan Presidential Library and Museum. I (Viki) have been raising alpacas since 2001, my main focus being the rare and elegant, Suri alpaca. I’ve tried to put together as informative a site as possible for your viewing but if you still have questions please don’t hesitate to ask. I work from home with my grooming business as well as the alpaca business so I can be reached most any time of the day or evening. Thank you for visiting my site.
