There's a small museum where you can learn how the local (Minnan-style) traditional houses are built.
A nice beach is a 5-10 min walk from the village.
One of Kinmen's 7 National Park villages, Oucuo has many traditional houses.
Typical of villages on this side of the island, Oucuo has a pond. It would have been built early in the village's life for 3 main purposes: feng shui, fire prevention and heat control.
As you walk around, notice that many traditional houses' rooftops have a flat section. These were originally used to dry things harvested from the nearby sea. Fishing is no longer the main source of income for Oucuo villagers, but the sea is still there to enjoy, of course.
It only takes about 10 min to walk down to the beach. If it's low tide, be on the lookout for the half-buried tank in the sand.
