Huckleberry Botanic Regional Preserve

Round Top is an extinct volcano in the Berkeley Hills, just east of Oakland, California. The peak lies entirely within the bounds of Contra Costa County. In 1936, the area surrounding the peak was established as Round Top Regional Park, one of the first three parks of the East Bay Regional Parks District. The park was renamed Sibley Volcanic Regional Preserve for the second president of the park district (1948 to 1958), Robert Sibley, shortly after his death in 1958. The eruptions that lead to Round Top started 10.2 Million years ago and ended more than a million years later. Two main vents of the old volcano are known, one is now under the Lawrence Berkeley National Laboratory, the other is Round Top. The Round Top vent has, over the years, fallen sideways.

Oakland Hills is an informal term used to indicate the city neighborhoods lying within the eastern portion of Oakland, California. The northernmost neighborhoods were devastated by the Oakland firestorm of 1991.

Robert Sibley Volcanic Regional Preserve is located in the Oakland Hills of the East Bay region of the San Francisco Bay Area, California. The park is part of the East Bay Regional Parks District (EBRPD), covers 928 acres (3.76 km2), and lies east of Oakland, partly in Alameda County and partly in Contra Costa County. It can be entered from Oakland via Skyline Boulevard, or from Contra Costa County via Old Tunnel Road.

Piedmont Pines is an affluent residential neighborhood in the hills of Oakland, California. It is generally bounded by Highway 13 (the Warren Freeway) to the west, Shepherd Canyon Rd. to the north, Skyline Blvd. to the east, and Joaquin Miller Park to the south. Two Oakland public schools are included in the area, Montera Middle School and Joaquin Miller Elementary School. There is no business section in Piedmont Pines. Although listed as a distinct district, realtors-architects, city government, and many Piedmont Pines residents have long considered the neighborhood as part of the larger Montclair district. Piedmont Pines is relatively remote from the city center and generally less known than Montclair; many Oaklanders do not seem to know of Piedmont Pines and consider this area to be part of the Montclair district, given that architecturally, geographically, demographically, and economically, the two affluent areas are virtually indistinguishable. The neighborhood's real estate includes a 1957 mid-century modern mansion by Oakland-born architect Roger Lee and an Arts and Crafts house rented by Grateful Dead sound engineer Owsley Stanley.

Montclair (also known as the Montclair District or Montclair Village) is a neighborhood in Oakland, California, United States. Montclair is located along the western slope of the Oakland Hills from a valley formed by the Hayward Fault to the upper ridge of the hills. Although there is no formal definition of the neighborhood, the general boundaries are Highway 24 to the north, Joaquin Miller Road to the south, the city of Piedmont to the west and the Contra Costa County border to the east. The center of the neighborhood is a compact shopping district known as Montclair Village which is located next to Highway 13 in the bottom of the valley. It lies at an elevation of 640 feet (195 m).

The Caldecott Tunnel fire killed seven people in the third (then-northernmost) bore of the Caldecott Tunnel, on State Route 24 between Oakland and Orinda in the U.S. state of California, just after midnight on 7 April 1982. It is one of the few major tunnel fires involving a cargo normally considered to be highly flammable, namely gasoline. At the time of the fire, the Caldecott tunnel complex consisted of three bores side-by-side, each 0.7 mi long (1.1 km). The then-northernmost bore, where the fire occurred, is dedicated to westbound traffic, traveling from Orinda to Oakland. It has a slope of approximately 4.7%, going downhill from the entry portal to the exit portal.

Canyon, formerly known as Sequoya, is an unincorporated community located near the border of Contra Costa and Alameda counties, in the U.S. state of California. It is situated between Oakland and Moraga in the San Francisco Bay Area. The community is named for its location in the upper canyon of San Leandro Creek along the eastern slope of the Berkeley Hills. Canyon lies at an elevation of 1138 feet (347 m).The community is mainly traversed by Pinehurst Road and Canyon Road. The homes of the community are nestled amongst the steep, narrow private roads and footpaths that extend from the redwood groves and ferns along the creek, through the mixed live oak, bay, and madrone forests on the steep hillsides, up to the chaparral and knobcone pines that grow along the ridge.

Since 2000, the Center has been located on the western border of Redwoods Regional Park.

The Caldecott Tunnel is an east–west highway tunnel through the Berkeley Hills between Oakland and Orinda, California. Its four bores carry California State Route 24. Named after Thomas E. Caldecott, former mayor of Berkeley, it opened in 1937 as a two-bore tunnel. The third bore opened in 1964 and the fourth bore in 2013. Currently, the two oldest bores carry eastbound traffic and the two newest bores carry westbound traffic.
