Bayukbok Caves map.

Legend in English: Daanan:way, Yungib:Cave, Bahayan:Residences, Tulay na Kable:Cable Bridge, Palanguyan:Swimming Area, Piknikan:Picnic Area. As you can see here at the Map there are lots of "Yungib".

Spelunking started from crossing the Madlum river and entered forested area after our Mt. Manalmon hike. However if you just came for this exciting activity, no need to cross of course and just ask locals for guide. 

The Music room.

The Bayukbok Caves are one of the historical places in Bulacan which can be found at the territory of Biak na Bato National Park. Based on Philippine history, these were hidding spot of guerrillas from Japanese colony.

Because of its formation, locals named some part of the cave with unique features like the "Music Room", where one can percuss it's longitudinal columns on the side which can produce different tone of sound.

A coral-like limestone formation

Bayukbok caves have so many rock forms to offer, from sedimentary to limestone. Its slippery ground and small opennings made cave explaration more exciting, revealed by lights from lamps striking it's rays on sparkling minerals.

Cave's ceiling, looks like a scene in heaven.

From cave 1, we went to another cave, much harder, steeper and narrower. We had to rock climb and entered again forested area just to get there. After continuous darkness from the first cave, light was finally seen upon start of the second.

If you are observant and differentiate the two caves, you will notice the difference from it's ceiling; rougher and tree roots are all dangling above.

Another unique feature in a certain part of this second cave is scattered snail shells all over the ground, not to mention that it is several meters higher than the first one, which signifies that waters flowed along that area before.
