The Sierra Vista Trail in the Dos Vientos section of Newbury Park is a roughly one mile long trail that connects the Vista Del Mar Trail on the west to the Potrero Ridge Trail on the east. The entry point on the west side is off of Rancho Dos Vientos just south of Via El Cerro and on the east side is on Via Las Brisas near Paseo Santa Rosa. As with most trails in this area, you will be treated with some great views of the surrounding mountains and neighborhoods. This trail is maintained by the Conejo Open Space Foundation.
