The Jiji Weir is located under the Jiji Bridge in Nantou and is currently the largest river weir in Taiwan. The scenery of the weir is very majestic, and you can enjoy the expansive view of the river from the observation deck of the Jiji Weir Management Center. The management center also has exhibition halls such as the Jiji Common Diversion Hall, the Jhuoshuei River Hall, and the Taiwan Water Resources Hall, which not only provide visitors with a great view of the landscape, but also allow them to get closer to the hydrological ecology.
