Pasig River - Geography

Geography

The Pasig River winds generally north-westward for some 25 kilometres (15.5 mi) from the Laguna de Bay, the largest lake in the Philippines, to Manila Bay, in the southern part of the island of Luzon. From the lake, the river runs between Taguig City, and Taytay, Rizal, before entering Pasig City. This portion of the Pasig River, to the confluence with the Marikina River tributary, is known as the Napindan River or Napindan Channel. From there, the river forms the common border between Makati City to the south and Pasig City, followed by Mandaluyong City to the north. The river then sharply turns northeast, where it has become the border between Mandaluyong and Manila before turning again westward, joining its other major tributary, the San Juan River, and then following a sinuous path through the center of Manila before emptying into the bay.

The whole river and most portions of its tributaries lie entirely within Metro Manila, the metropolitan region of the capital. Isla de Convalescencia (14°35′26″N 120°59′20″E / 14.59056°N 120.98889°E / 14.59056; 120.98889), the only island dividing the Pasig River, can be found in Manila and it is where the Hospicio de San Jose is located.
