A sprawling national park that also covers parts of the neighboring towns of San Miguel and San Ildefonso. Famous as the site of the Biak-na-Bato Republic, a proto-state founded by Filipino separatists during the Philippine Revolution against Spain in 1897, it also contains caves, rivers and forested highlands of the Sierra Madre that belie the misconception of Bulacan as a largely flat province.
Biak-na-Bato National Park is a protected area of the Philippines located almost entirely within Barangay Biak-na-Bato in San Miguel, Bulacan from where it derives its name. The park also extends to the nearby municipalities of San Ildefonso and Doña Remedios Trinidad covering a total area of 2,117 hectares. It was declared a national park in 1937 by President Manuel L. Quezon by virtue of its association with the history and site of the Republic of Biak-na-Bato. The park consists of a cave network and a system of rivers and trails of both historical and ecological importance. Situated only 80 kilometers (50 mi) northeast from Manila, it is fast becoming a popular weekend eco-adventure destination for the city dwellers.
