At the center of Left Bank is a visitor's center that has been redone to become the Taipei County Sustainable Development Education Center. Therein, you'll find an information desk, exhibition area and multi-purpose classrooms educating on wetland management and the effects of global warming. Old Banyan Pillbox hidden in Bali Rive Gauche (Left Bank) near an old banyan tree is a camouflaged building. Since the army base was decommissioned, this became a sight-seeing vantage point open to visitors who want to get a high view of Tamsui River.
