Arroyo Conejo (Spanish for “Rabbit Creek”) is the longest creek in the Conejo Valley, sprawling over the cities of Thousand Oaks and Camarillo, and the communities of Newbury Park, Casa Conejo and Santa Rosa Valley. Arroyo Conejo is the primary drainage for the City of Thousand Oaks. Its watershed covers 57 square miles (150 km2) of which 43 square miles (110 km2) are in the Conejo Valley and 14 square miles (36 km2) in the Santa Rosa Valley. Within Wildwood Regional Park, its gorge and its 40-foot (12 m) cascade, Paradise Falls, are among the park’s most visited attractions.
