The mouth of the Dadu River is the largest resting site for water birds in central Taiwan. It is the country's best place for bird watching. Of the birds to be seen here, 24 are listed as protected species. The area has been named by the International Nature Resource Conservation Federation as one of Asia's most important wetlands. The best bird watching season at Dadu River is October through May. December through April is the best time to see waders and other water birds. It is important to check tide times before planning a trip.
There are no public buses to this area, so it is best to go by car. Leave the Sun Yat-sen Freeway at the Wangtian Interchange and take Provincial Route No. 17 toward Dadu. When you reach the coastal barrier, you are at the bird watching area.
