This is a short video of the resort we found on youtube.
This resort is around 1 hour drive from Metro Manila starting from the Balintawak tollgate exit of the North Luzon Expressway. It is a neighboring town of Baliuag, Bulacan and a town that passes if you are going to the province of Nueva Ecija.
