Thousand Oaks sits in the Conejo Valley, ringed by the Santa Monica Mountains and the Simi Hills, with oak trees giving the city its name and its shaded streets. Wildwood Regional Park offers canyons, waterfalls in wet seasons, and trails that climb toward wide valley views, while the Gardens of the World presents themed gardens, waterfalls, and quiet paths close to downtown. The Civic Arts Plaza brings theatre and concerts to the city center, so outdoor days and indoor evenings share the same calendar.
