Margaret and Dennis Allan purchased the 500 acre Rocky Creek Cattle Ranch from the Boysen Family in 2004. This beautiful ranch is located on the southern border of the historic Tar Springs Ranch in the Huasna Valley of Arroyo Grande. Prior to the purchase, no one had resided on the ranch in any known history. The ranch features open valleys, mountains, giant rock formations, streams and seasonal ponds. The ranch is covered with many varieties of oak trees. It is home to many wild animals including foxes, bobcats, cougars, coyotes, bears, skunks, deer and raccoons. Rocky Creek Cattle Ranch was named after the rocky creek beds that meander through the ranch. During wet years, many waterfalls can be found throughout the ranch. Hundreds of multi-colored wild flowers are found in the spring.
