Hidden among rock-studded hills, Lake Perris State Recreation Area's 8,800 acres of broad valley are bounded on three sides by low ridges. The Bernasconi Hills and the Russell, Apuma and Armada Mountains obscure the view of nearby cities. Inland, the San Bernardino, San Jacinto and Santa Rosa Mountains, snow-capped in winter months, stand tall in the distance. This area, with its varied terrain and habitats, is rich in a variety of wildlife. About 65 miles south of Los Angeles and 11 miles southeast of the city of Riverside, Lake Perris's clean white beaches, enticing blue waters, and rocky Alessandro Island bring nearly one million visitors each year from surrounding communities. Activities in this popular park include fishing, water sports, bird watching, hiking, rock climbing, camping, horseback riding, and visiting the Ya'i Heki' (pronounced yahee ehkey) Regional Indian Museum.
