The Hong Kong UNESCO Global Geopark is a network of coastal and island sites covering over 150 km2 in the eastern and northeastern New Territories, established in 2009 and listed by UNESCO as a Global Geopark in 2011. It protects two contrasting geological regions across Sai Kung and East New Territories in Hong Kong.
The Sai Kung Volcanic Rock Region is famous for extensive tuff and other volcanic rocks showing prismatic columnar jointing: notable places include High Island, the Ung Kong island group and the Ninepin islands where sub-vertical columns form sheer cliffs, sea arches and caves. Sharp Island and nearby coastlines show volcanic-related sediments and a tombolo that appears at low tide.
The Northeast New Territories Sedimentary Rock Region preserves a long sequence of sedimentary rocks and coastal landforms: Double Haven and Port Island (Chek Chau) display rust-colored Tertiary beds, Ma Shi Chau and Lai Chi Chong expose fossil-bearing and deformed sediments, and Tung Ping Chau is known for its wave-eroded shale and unusually flat, pancake-like layering. The geopark is dispersed - many key sights are on offshore islands or remote shorelines reached by boat or long walks, with limited facilities at most locations.
- High Island columnar joints: Tall, parallel prismatic columns of volcanic tuff visible along cliffs and around the High Island Reservoir area.
- Ung Kong and Ninepin sea cliffs: Sea-eroded cliffs, sea arches and giant columnar joints that form dramatic coastal scenery around these offshore islands.
- Sharp Island tombolo: A sand and rock tombolo that links at low tide to a small islet, exposing shoreline features and tuff-related sediments.
- Double Haven and Port Island (Chek Chau): Calm harbour scenery and rust-colored sedimentary beds on Port Island, where recent fossil discoveries have been reported.
- Tung Ping Chau wave-eroded shale: A flat, wave-sculpted island surface with unusual shale layering and reef-like rock formations popular with day-trippers.

How to Get to Hong Kong UNESCO Global Geopark#
The geopark sits east and northeast of urban Hong Kong; the most common gateway for the volcanic Sai Kung sites is Sai Kung Town, while several sedimentary outcrops and islands are reached from piers around Tolo Harbour and the northeastern New Territories. The main international gateway is Hong Kong International Airport; travel into the city by rail or road then onward by public transport or taxi to local piers and towns.
Most of the best-known coastal sites are reached by boat from Sai Kung Town (take services or join tours) or by walking from village trailheads along the northeastern shores; some islands have scheduled or charter boat runs while others require joining a guided trip. For remote sites expect a final stretch by small boat, a coastal hike or a short local transfer - check local pier departure points, tour operators and tide times before you travel.
Tips for Visiting Hong Kong UNESCO Global Geopark#
- Wear sturdy, non-slip footwear - many viewpoints and coastal routes are on uneven volcanic rock or slippery shale.
- Tide and sea conditions matter: the Sharp Island tombolo and some sea caves are accessible only at low tide or in calm weather.
- Do not remove rock samples, fossils or flora - the geopark is protected and many features are scientifically important.
- Bring water, sun protection and rain gear; many sites have no facilities and Hong Kong can be hot and rainy in summer.
- If you plan island visits, use licensed boat operators or guided tours and check weather/typhoon warnings before heading out to sea.
