Beimen Lagoon is a shallow coastal lagoon in Beimen District, Tainan, within the Southwest Coast National Scenic Area. From roughly October through April each year, tens of thousands of whiskered terns overwinter here, forming a spectacular murmuration-like display in the sky at dusk. Surrounding the lagoon are Beimen Salt Fields and Jingzijiao Tile-Pan Salt Fields, and the image of the setting sun reflected across the salt field waters is also a celebrated photography subject that draws large numbers of photographers gathering in the afternoon to wait for the light.
Beimen Lagoon is part of the Southwest Coast National Scenic Area, not Taijiang National Park; each year from roughly October through April, tens of thousands of whiskered terns overwinter here, returning from nearby fish farms at dusk to circle and flock above the lagoon in a display locally known as the "dusk dance." Taiwan's most important black-faced spoonbill reserve is instead located in Qigu, about an hour's drive to the south, within Taijiang National Park.
What to see at Beimen Lagoon
Beimen Lagoon is part of the coastal wetland system of Taijiang National Park. Geographically it is a shallow body of water enclosed by sandbars and the coastline, with shallow depth and a sandy-mud bottom well suited to wading birds and waterbirds. Each autumn and winter, roughly October through March of the following year, migratory birds pass through and overwinter here. The black-faced spoonbill is the most prized rare species among them; the Black-faced Spoonbill Conservation Area in Qigu is within the nearby area.
The Beimen Salt Fields surrounding the lagoon are a historic relic of Taiwan's salt industry. The vast expanse of salt field water reflects a deep orange-red glow when sunlight hits it, creating a striking visual effect that is one of the most iconic sunset photography scenes along Taiwan's southwest coast. The area's open horizon with no tall buildings in the way allows views of clouds and sky gradients in the distance, suitable for a range of compositions from wide-angle to telephoto.
