ALTAY, Xinjiang，Jan.5, 2026 ,Visitors flocked to the Sea Devil City at Wulengur Lake in Fuhai County, Altay Region, Xinjiang, to enjoy winter activities like sledding and snow play against a backdrop of surreal geological formations.
Located on the eastern shore of Jili Lake, part of the larger Wulengur Lake basin, the Sea Devil City (also known locally as the Sea Yadan) is renowned for its dramatic Yadan landforms — sculpted across millions of years by wind and water erosion from soft sedimentary rocks dating back to the Late Cretaceous period. These unusual formations stretch in a north–south orientation for more than ten miles, rising up to 20 meters in places and resembling ancient castles, palaces, and mythical figures perched above calm lake waters.
Travel writers and explorers have dubbed the site a “wetland education gallery, a Yadan geological wonder,” and even a “living Devil City” for its otherworldly shapes and ever-changing light and shadow. The combination of water-linked Yadan scenery and the vastness of Wulengur Lake creates a striking contrast — rare among the world’s geological landscapes.
A Four-Season Destination
While summer draws visitors for boating, bird-watching and scenic walks along wooden boardwalks, the winter season transforms Sea Devil City into a dynamic playground of snow and ice. The region’s snow-covered ridges and sculpted cliffs create dramatic vistas as white blankets accentuate every contour.
This winter, a range of ice-and-snow tourism offerings has drawn visitors from across China and beyond. At the heart of the experience are:
Ice and snow parks for family fun Snowmobiles and ice drifting Winter fishing on frozen lake surfaces VR adventure experiences that showcase the geology and cultural heritage of the region Traditional sledding and snow play for all ages
These offerings align with Altay’s broader push to become one of the premier winter tourism hubs in northwest China, blending outdoor recreation with cultural immersion and ecological appreciation.
Cultural and Ecological Richness
Beyond its geological wonders, Sea Devil City sits within a vibrant ecological and cultural landscape. Wulengur Lake and its wetlands support a habitat for waterbirds, fish and sand-adapted plants, making it a rich site for wildlife observation and environmental education. The nearby township communities offer cultural insights into the ethnic traditions and hospitality of northern Xinjiang.
As Altay’s winter tourism grows — powered by infrastructure improvements and diverse seasonal programming — Sea Devil City is emerging as a standout destination where ancient geological artistry meets modern winter fun. Its surreal formations and snowy splendor offer an unforgettable experience for adventurers, photographers and travellers seeking a unique blend of nature and culture in one of China’s most compelling landscapes.
