香港二疊紀園–馬屎洲特別地區
馬屎洲特別地區面積共61公頃，範圍涵蓋吐露港內的馬屎洲、洋洲、丫洲及三門仔新村東北面的一個未命名島嶼。馬屎洲是香港二疊紀「大埔海組」的要址，島上岩石露頭出露良好，加上存在斷層和褶皺構造，岩層亦發生變形或錯斷，形態複雜，因此最適合研究地層、岩性、沉積特徵和各類地質構造。此外，鹽田仔旁的無名小島茂林密布，吸引了大群白鷺棲息，除了地質景觀外亦深具生態保護價值，政府遂於1999年將該局劃為特別地區。
馬屎州特別地區的自然教育徑位於小島東南面海旁，全長1.5公里，共有16個景點。這條徑道以岩石為主要特色，遊人可透過實地觀察及細閱傳意牌，了解連島沙洲及多種岩石的形成過程，以及海蝕、風化和褶曲等的地質現象。

The 61-hectare Ma Shi Chau Special Area is made up of Ma Shi Chau, Yeung Chau, Centre Island and an unnamed islet to the northeast of Sam Mun Tsai New Village. Ma Shi Chau is the key site of Hong Kong's Permian Tolo Harbour Formation. Home to well-outcropped rocks, the island is an ideal location for studying strata, rock properties, sedimentation features and different geological compositions because here you can find faults and folds as well as deformed and displaced rock mass. The unnamed islet near Yim Tin Tsai, vegetated with dense woodlands, is a popular roosting ground for egrets and herons. Given such outstanding conservation value, the Ma Shi Chau region was declared a protected Special Area in 1999.
The Ma Shi Chau Special Area nature trail runs along the southeastern shore of the island. 1.5 km in length, this route presents 16 attractions which highlight local geological features. By observing the rocks on site and reading trailside interpretation plates, visitors can understand how tombolos and various rocks are formed, as well as natural phenomena like wave erosion, weathering and folding .
