Rolling Hills consists of a single gated community. Residents work, shop, attend school, and obtain other services in the other towns on the Palos Verdes Peninsula.

The city borders Rolling Hills Estates to the north and Rancho Palos Verdes on all other sides (including the empty Portuguese Bend landslide area to the south).
According to the United States Census Bureau, the city has a total area of 3.0 square miles, all land.
