Hong Kong protects approximately 40 percent of its 1,110 square kilometers of land area through a system of country parks, special areas, marine parks, and conservation zones established under the Country Parks Ordinance of 1976. The Agriculture, Fisheries and Conservation Department manages 24 country parks and 22 special areas totaling 443 square kilometers, alongside five marine parks and one marine reserve covering 34 square kilometers of coastal waters. This protection system reflects a deliberate policy choice made in the 1970s to preserve the mountainous terrain unsuitable for urban development while concentrating the 7.5 million population into approximately 25 percent of the total land area, primarily along the northern coastal strip of Hong Kong Island, the Kowloon Peninsula, and parts of the New Territories.
Tai Mo Shan Country Park encompasses 14.4 square kilometers surrounding Hong Kong's highest peak at 957 meters above sea level, gazetted as a country park in 1979. The mountain itself stands in the central New Territories between Tsuen Wan and Yuen Long, with the park boundary protecting secondary forest that regenerated after agricultural abandonment in the mid-20th century. The summit remains closed to public access as it hosts transmission facilities for Hong Kong's broadcast networks and telecommunications infrastructure, but marked trails approach to within 100 vertical meters of the peak. The Tai Mo Shan Country Park receives approximately 500,000 visitors annually who use the network of walking trails including sections of the Wilson Trail, which crosses the park north to south. Vegetation zones shift noticeably with elevation, from feng shui woods of Chinese banyan and incense trees at lower elevations to stunted montane forest dominated by Gordonia axillaris and rhodomyrtus tomentosa above 600 meters. The area records Hong Kong's lowest temperatures, with the Hong Kong Observatory measuring -6 degrees Celsius at the summit on January 24, 2016, though typical winter minimums at 900 meters altitude range from 5 to 10 degrees Celsius while coastal areas remain above 15 degrees.
Sai Kung East Country Park covers 44.8 square kilometers on the eastern New Territories peninsula, designated in 1978 to protect Hong Kong's most extensive remaining coastal wilderness. The park includes Sharp Peak at 468 meters, which rises directly from sea level on the Tai Long Wan coastline to create Hong Kong's most dramatic vertical coastal relief. Four beaches at Tai Long Wan—Sai Wan, Ham Tin Wan, Tai Wan, and Tung Wan—remain accessible only by trail or boat, with no road access, preserving these kilometer-long sand beaches in near-natural condition. The MacLehose Trail traverses the park for approximately 20 kilometers, including the technically demanding section over Sharp Peak that requires scrambling over exposed volcanic rock. Sai Kung volcanic rock group formations, dated to 140 million years ago during the Jurassic-Cretaceous transition, form the hexagonal columnar joints visible at High Island Reservoir East Dam and throughout the coastal cliffs. The Hong Kong UNESCO Global Geopark designated in 2011 includes substantial portions of Sai Kung East Country Park, with the Sai Kung Volcanic Rock Region representing one of the geopark's two main geological areas. Popular entry points include Pak Tam Au, accessible by public bus from Sai Kung town, and Wong Shek Pier, which also serves as a departure point for kaito boats to beaches and islands.
Plover Cove Country Park extends across 47.8 square kilometers in the northeastern New Territories, established in 1979 around the Plover Cove Reservoir constructed between 1960 and 1968. The reservoir itself was created by building a 2.1-kilometer dam across the mouth of Plover Cove, converting the former marine inlet into Hong Kong's second-largest freshwater storage facility with a capacity of 230 million cubic meters. Pat Sin Leng, a ridge forming the southern boundary of the country park, reaches 639 meters at its highest point and translates as "ridge of eight immortals," named after eight teachers who died on the mountain during a 1996 hiking accident when weather conditions deteriorated. The MacLehose Trail section crossing Pat Sin Leng Country Park, which adjoins Plover Cove Country Park to the south, is considered among Hong Kong's most challenging day hikes due to the sustained ridge walking with exposure to weather and limited escape routes between the eight peaks. Bride's Pool, located in the northeastern section of Plover Cove Country Park, is a natural waterfall and plunge pool accessible via a 1. The country park provides habitat for wild boar populations that have increased substantially since the 1990s, with the Agriculture, Fisheries and Conservation Department estimating several thousand individuals across Hong Kong's country parks, though precise census data is not published.
Mai Po Nature Reserve occupies 380 hectares of wetland in the northwestern New Territories adjacent to the Shenzhen River border with mainland China, managed by World Wide Fund for Nature Hong Kong under agreement with the Agriculture, Fisheries and Conservation Department since 1983. The reserve was designated a Ramsar Wetland of International Importance in 1995, recognizing its role as a critical refueling point for migratory waterbirds traveling the East Asian-Australasian Flyway between Arctic breeding grounds and southern wintering areas. The Inner Deep Bay area, which includes Mai Po, supports populations of the globally endangered black-faced spoonbill, with winter counts typically recording 300 to 400 individuals out of a world population that reached 6,162 in the 2023 census coordinated by the Hong Kong Bird Watching Society. Mai Po's gei wai system—traditional shrimp farming ponds adapted for conservation purposes—covers approximately 240 hectares within the reserve, with water levels manipulated seasonally to create optimal feeding conditions for different waterbird species. Access requires a permit obtained in advance from World Wide Fund for Nature Hong Kong, with visitor numbers limited to preserve the site's conservation value. Boardwalks and observation hides allow viewing of mudflats that support invertebrate populations critical for migratory shorebird feeding, though the educational center closed in 2020 has not reopened as of early 2024. The reserve records approximately 380 bird species, representing about 60 percent of Hong Kong's total bird species count, despite covering less than 0.4 percent of the territory's land area.
Hong Kong Wetland Park covers 61 hectares adjacent to Mai Po Nature Reserve, opened in 2006 as a public education facility distinct from the restricted-access conservation areas. The park includes a 10,000-square-meter visitor center designed by architectural firm Simon Kwan & Associates, with exhibition galleries, a theater, and teaching facilities, alongside outdoor wetland habitats including freshwater marsh, reed beds, mangrove stands, and mudflats. A resident saltwater crocodile, confirmed through sightings beginning in 2003 and captured in 2006, resided in a purpose-built enclosure at the park until its death in 2023 after approximately 20 years in captivity. The crocodile was identified as a Crocodylus porosus individual likely escaped from a farm in mainland China, measuring approximately 2 meters in length at capture. Wetland Park's constructed habitats include a 10-hectare wetland reserve closed to public access to allow undisturbed use by waterbirds, visible from hides positioned around the perimeter. The park charges an admission fee of 30 Hong Kong dollars for adults as of 2024, with reduced rates for students and seniors, and receives approximately 400,000 visitors annually. Three themed walking routes—Wetland Walk, Stream Walk, and Mangrove Boardwalk—total approximately 1.5 kilometers and connect different habitat zones within the park.
