The Aguinaldo Cave, also known as the Cuarto-Cuarto Cave, is located in San Miguel, Bulacan. There are three prominent caves exist along the banks of the Balaong River that circumscribe the historic barangay of Biak-na-Bato, namely Bahay Paniki Cave, Aguinaldo Cave and Bukal Cave. The most notable of these caves is the Aguinaldo Cave where the late hero, General Emilio Aguinaldo, once took refuge while leading the resistance movement against the Spanish and American colonizers. Militarily, its narrow but long entrance coupled with the existence of secret chambers can way-lay intruders. The enemy has to literally crawl through the low portal and would ran smack against the waiting defenses of Aguinaldo’s men. Aside from the presence of stalactites and stalagmites which come in various hues and sizes, the cave also boasts of palisades or rows of columns (stalactites and stalagmites which have united in the course of time) which local residents refer to as the Cuarto-Cuarto Cave or cave of many chambers. Some palisades have developed into walls, partitioning off the cave area into several rooms. The cavern has two long, branching natural tunnels: one extending from the portal to about 130 meters horizontally lain; the other descended by a vertical crevice about 10 feet deep which situates the various chambers. To reach several of these, one has to wiggle, waggle, wriggle, squirm, push and pull to get to the inside. At the lower mouth of the cave, one can sit on the rocks and cool off with naturally chilled air from an underground cold spring. The cave is entered via a higher orifice, and one must clamber down to get to the water’s edge. A ten-minute boat ride into this eerie underground river leads to a stalactite-accented cavern where, at its center, a smooth triangular block of marble juts above the surface of the clear emerald water. Local lore claims it to be “la mesa de Aguinaldo”, the table on which Aguinaldo signed the historic peace treaty.
To get to Aguinaldo Cave, take the North Luzon Tollway and exit at Sta. Rita/Baliuag (exit 32A/32B). From the exit, head north along the National Highway towards Plaridel, Baliuag, San Ildefonso (about 28 km). About 7 kilometers from San Ildefonso, keep an eye for a Y intersection. It should have a sign that points to Biak na Bato National Park. Take that road on the right and then, about 1 km farther, there would be another intersection, and the road on the right (eastward) will lead straight to Biak na Bato.
