Spring Mountain Ranch State Park

Spring Mountain Ranch State Park
Spring Mountain Ranch State Park, adjacent to the Red Rock Canyon National Conservation Area, “…has been used historically as a working ranch and a luxury retreat by a string of colorful owners, including German actress Vera Krupp and millionaire Howard Hughes. Today visitors can explore some of the oldest buildings in Nevada, a 1860s blacksmith shop, the Sandstone Cabin that was home to the founding family and the ranch house. Hiking trails throughout the park, in addition to tree-shaded picnic sites with tables and grills, make day trips to the park a family favorite. ”  Thank you David Low, for your help.
