Migratory Bird Sanctuaries along Yellow Sea-Bohai Gulf of China - UNESCO site, world largest intertidal mudflat. Phase 1 2019, Phase 2 2024.

This is a site for committed birders, not casual tourists. The mudflats are vast, flat, and visually unspectacular — a brown horizon meeting a gray sky. But if you are the kind of person who will travel 10 hours to see a single spoon-billed sandpiper, this is one of the most important birding sites on the planet. During spring migration (April–May), the numbers are staggering: tens of thousands of shorebirds feeding on the tidal flats at once. Bring a spotting scope. The red-crowned crane reserve in winter is more visually rewarding for non-birders — the cranes dance in the snow.
Spring migration (April–May) has the highest shorebird numbers — tens of thousands of birds refuel on the mudflats before heading to Siberia. Autumn migration (September–October) has fewer birds but includes juveniles on their first migration. Winter (November–February) is for red-crowned cranes and other wintering species.
It is possible but not guaranteed. The spoon-billed sandpiper is critically endangered — fewer than 500 adults remain. Yancheng is one of the few reliable stopover sites during spring and autumn migration. You will need a spotting scope, patience, and ideally a knowledgeable guide. The best time is April–May.
Honestly, no. The landscape is vast, flat mudflats — ecologically critical but visually unspectacular. The red-crowned crane reserve in winter (with cranes dancing in the snow) and the Dafeng Milu deer reserve are more accessible to non-birders. This is a site that rewards knowledge and patience above all.
HSR to Yancheng Station from Shanghai (2h) or Nanjing (2h). The reserves are 50–80 km from the city — hire a car with driver for the day (¥500–800). The red-crowned crane and milu deer reserves are in different directions (north vs. southeast of the city). There is no useful public transport between them.
A large wetland deer native to China that went extinct in the wild by 1900. The last wild herd lived in the Qing imperial hunting park in Beijing. A few individuals were sent to European zoos in the 19th century. All living milu descend from 18 animals in the Duke of Bedford's Woburn Abbey herd. They were reintroduced to China in 1986 at Dafeng, and the wild population now exceeds 5,000.
