The Pasig River is a vital waterway in the Philippines, flowing through the capital city of Manila and connecting Laguna de Bay to Manila Bay. It spans approximately 27 kilometers and serves as a natural boundary between several cities, including Pasig, Mandaluyong, and Quezon City. The river has historically been important for trade and transportation. Over the years, the Pasig River has faced significant pollution and environmental challenges. Efforts have been made to rehabilitate the river, including clean-up initiatives and the establishment of parks along its banks. The river is also a key feature in the urban landscape, providing recreational opportunities for residents and visitors.
