Biak-na-Bato National Park

San Miguel, Bulacan

A dramatic karst landscape of caves, ravines, and underground rivers in the limestone hills of San Miguel, Bulacan. Andrés Bonifacio's Katipunan used these caves as a revolutionary headquarters in 1896; Emilio Aguinaldo signed the Pact of Biak-na-Bato here in 1897. The park draws cavers and historians in equal numbers—some chambers still bear traces of that era's occupation.
