Lüyashan Island

　　Sunrise over the Sea: On a tranquil morning, a gentle sea breeze blows as the sky meets the water. Suddenly, rays of sunlight burst forth, turning the waves a dazzling crimson, shimmering with golden highlights scattered across the surface, casting countless golden sparkles onto the sea – a magnificent spectacle.

　　Tour Guide

　　Located 4 nautical miles northeast of Dongzao Port in Haimen City, in the Yellow Sea, this is a natural amphibious biological island. It emerges as a reef at high tide and becomes an island at low tide, standing about 4.5 meters above sea level on average. It is formed by the accumulation of over 30 varying-sized oyster mounds, commonly known as Huangnizao, Hongxidui, Damasan, and Shiba Tiao.

　　Introduction

　　The island is rich in resources and offers a unique landscape, particularly famous for its abundant oysters, hence the name Lüyashan (Oyster Mountain). Local fishermen often call it Lüyashadui (Oyster Pile).

　　Lüyashan is an oyster reef that has formed on a vast expanse of silt – a phenomenon rarely seen, as biological reefs typically grow on stones or hydraulic structures such as sluice gates. This type of silt-formed reef is unprecedented, with no records found in relevant scientific literature. Experts believe this puzzling and extraordinary marine wonder provides a rare reference point for studying mid-latitude paleoceanographic changes over the past 20,000 years. It leaves many unanswered questions, making it highly valuable for in-depth research, and offers significant potential for promoting marine science education, exploring marine geology, climate, biological changes, and developing eco-tourism.

　　The Lüyashan Ecotourism route has been opened, featuring recommended activities such as harbor scenery tours, leisure cruises, viewing the peculiar oyster mountain, watching the sunrise at sea, tidal flat foraging, catching marine life, and riding colorful horse-drawn carts.

　　Uniquely Fresh Oysters: Lüyashan provides local fishermen with abundant seafood resources, especially oysters. A popular local dish involves adding just a drop of oil, a pinch of salt, and a ladle of water to a pot, then heating it over a flame without any additional seasonings to create a delicious and savory oyster soup – famously known as “Uniquely Fresh Oysters.”
