Montecito occupies the eastern portion of the coastal plain south of the Santa Ynez Mountains. Parts of the community are built on the lower foothills of the range. Montecito, however, does not include areas such as Coast Village Road, which are usually considered part of Montecito but are actually within the city limits of Santa Barbara. Notable roads spanning Montecito include East Valley Road, Mountain Drive, and Sycamore Canyon Road, all of which form part of State Route 192. In addition, the U.S. 101 Freeway runs along the south end of town, connecting it with other cities in Santa Barbara County and the rest of Southern California.
