Mount Gough is a hill in Hong Kong, 465 metres above sea level, forming part of Victoria Peak on Hong Kong Island. Mount Gough is named after Gough, the British commander-in-chief in the Opium War.

Victoria Gap, also known as Lung Fung Gap or Peak Gap and commonly called The Peak, is a mountain pass between Victoria Peak and Mount Gough on Hong Kong Island.

Victoria Peak (Chinese: 太平山; Jyutping: taai3 ping4 saan1) is a hill on the western half of Hong Kong Island. It is also known as the Mount Austin, and locally as The Peak only generally. With an elevation of 552 metres (1,811 ft), it is the tallest hill on Hong Kong Island, and the 29th tallest in the territory of Hong Kong. It is a major tourist attraction, offering views of Central, Victoria Harbour, Lamma Island and the surrounding islands. The summit of Victoria Peak is occupied by a radio telecommunications facility and is closed to the public. The name The Peak is usually a reference to the surrounding area of public parks, tourist facilities and high-value residential land. The Peak also refers to Victoria Peak itself and its nearby areas, including Victoria Gap, Mount Kellett and Mount Gough. Sometimes Bowen Hill may also be included. The Peak is also known as a residential area consisting of different neighbourhoods including the less affluent Mount Kellett Road which faces Southside. The Peak is the third most expensive residential areas in Hong Kong. In 2025 and 2026, apartments and houses at La Hacienda, Mount Kellett Road, were sold at around HK$24,000 and HK$ 30,000 per square feet respectively, which represent about 30 percent lower than those in Jardine's Lookout and half of those in Deep Water Bay. The apartments' values are lower than equivalent ones on Mid-levels.

Mount Davis is the westernmost hill on Hong Kong Island, 260 metres (853 ft) above sea level, lying south of Kennedy Town and north of Pok Fu Lam, and marks the western end of Hong Kong Island. It is not a separate district, so it is mostly regarded as part of Pok Fu Lam, and it adjoins Green Island and Little Green Island, which face each other across the Sulphur Channel. The English name Mount Davis comes from Davis, the second Governor of Hong Kong. From Mount Davis one can take in the fine sea views west of Hong Kong Island: besides Green Island and Little Green Island across the Sulphur Channel, one can also look out to Lamma Island, Cheung Chau, Lantau Island, Peng Chau, Chow Kung Island and Kau Yi Chau and Siu Kau Yi Chau, and further off to the Tsing Ma Bridge, which also makes it a good place to watch the sunset.
