This is a good year-round bird watching spot.

This spot will appeal to military history buffs and naturalists alike.


The distinctive triangle-shaped fort is a landmark in Kinmen. The moat-like trench surrounding it was a defense measure against invaders. 
Ci Lake Triangle FortressThe minefield encircled by barbed wires on the beach, as well as the soldiers stationed here, are long gone. But you can still see tanks…

…and perhaps, butterflies and birds. In the late spring and early summer, the yellow beach primrose flowers attract butterflies and migratory blue-tailed bee-eaters.

Starting in November, in the winter, come at dusk to see flocks of migratory cormorants flying in from the sea. They're headed for trees on the shores of nearby Lake Ci to roost for the night.

Throughout the year at low tide, you should be able to watch shorebirds along the coastline here.

    An old fort, overlooking Xiamen & Guiyi, now better known for migratory bird watching. A nature bird-watching board is build in one of the small room within the fort. A consistent natural cool could be felt within this room. Some old tanks link both the sides of this fort, & history is the Pass. Besides the 10 of us (including the guide & driver), only a young family of 3 were here.

    Cihu Triangle Fortress was one of the few dozen forts all over the island. This one had binoculars that looked towards Xiamen and Guiyu that are few kilometers away. Few old tanks and an old military speaker are also near the grounds.

    Cihu Triangle Fort is a haven for bird watchers

    For a building intended for destructive purposes, it is now an interesting relic of a bygone era. The internal layout of the fortress is simplistic but the dimensions can be quite limiting and cramped at the three points which once formed machine gun posts. In the central living quarters area and along the hallways, there are now information signs about the local birdlife, especially linked with aquatic birds living at the neighbouring Ci Lake. The rooftop allows for greater movement, with nice views along the beachfront across to the lake.
