Grizzly Peak is a summit in the Berkeley Hills above Berkeley, California. The peak is located on the border between Alameda and Contra Costa counties, within the boundaries of Tilden Regional Park, and directly behind the University of California, Berkeley campus. The peak was named for the California grizzly bear which inhabited the local area until the late 1800s. The last sighting locally was by a man who was reportedly killed by a grizzly in Strawberry Canyon below Grizzly Peak in the 1860s. The first local killing of a grizzly by a European occurred in 1772, also along Strawberry Creek just west of what is today the UC Berkeley campus, within what is now downtown Berkeley. The shooting by Spanish soldiers was recorded by Father Juan Crespi. The last grizzly in all of California was killed in the Sierra foothills east of Fresno in August 1922.Grizzly Peak became more accessible in 1932 when Grizzly Peak Boulevard was constructed along the ridge line of the Berkeley Hills. The name was extended to the previously-constructed ridge line stretch of Euclid Avenue to the north shortly thereafter. This portion was and remains a residential area of Berkeley while the original stretch is largely undeveloped. Grizzly Peak Boulevard now extends from Kenyon Avenue in Kensington in the north, through Berkeley and Oakland to an intersection with Skyline Blvd. above Oakland to the south. Before Grizzly Peak Boulevard was constructed, the location of its current intersection with Claremont (before 1892 known as Telegraph Road) and Fish Ranch Road was historically an important pass through the Berkeley Hills, before the tunnel that preceded today's Caldecott Tunnel was constructed through the hills in 1903; an inn and stage stop called the Summit House was located here. Today, Grizzly Peak is a popular location for people to get a unique view of the Golden Gate Bridge and the surrounding Bay Area. It is also common to see street luge enthusiasts in this area and down the canyon into Berkeley from Skyline Boulevard and Claremont Avenue.

The University of California Botanical Garden is a 34-acre (13.7 ha) botanical garden located on the University of California, Berkeley campus, in Strawberry Canyon.

Claremont Canyon Regional Preserve is a small regional park mainly located in the city of Oakland, California, and administered by the East Bay Regional Park District. The park is named for the canyon in which it is situated, Claremont Canyon, out of which Claremont Creek flows on its way to its confluence with Temescal Creek. Originally, the canyon was named Harwood's Canyon, and then later as Telegraph Canyon. The name was changed to Claremont by a developer of the nearby Claremont district.

The Berkeley Hills are a range of the Pacific Coast Ranges that overlook the northeast side of the valley that encompasses San Francisco Bay. They were previously called the "Contra Costa Range/Hills" (from the original Spanish Sierra de la Contra Costa), but with the establishment of Berkeley and the University of California, the current usage was applied by geographers and gazetteers.

Julia Morgan Hall (formerly Girton Hall) is a historic building in the University of California Botanical Garden in Berkeley, California. Built in 1911, the building was designed by prominent California architect Julia Morgan and originally located on the central campus of the University of California, Berkeley, near the present location of the Haas School of Business. It served as a gathering place for Berkeley's female students, who wanted a female counterpart to Senior Hall, the senior men's meeting hall.

The Oakland firestorm of 1991 was a large suburban wildland–urban interface conflagration that occurred on the hillsides of northern Oakland, California, and southeastern Berkeley over the weekend of October 19–20, 1991, before being brought under full control on October 23. The official name of this incident by Cal Fire is the Tunnel Fire. However, it is also commonly referred to as the Oakland Hills firestorm or the East Bay Hills fire. The fire ultimately killed 25 people and injured 150 others. The 1,520 acres (620 ha) destroyed included 2,843 single-family dwellings and 437 apartment and condominium units. The economic loss from the fire was estimated at $1.5 billion ($2.59 billion in 2021 dollars).
