Biak-na-Bato National Park

I got an invitation from Jesu-Mariae School (JMS), my son Jandy’s school, to join an outbound education demonstration tour for teachers at Biak-na-Bato National Park in Bulacan sponsored by Lakbay Kalikasan and I promptly accepted.  Five JMS teachers were to accompany me – Ms. Ofelia “Openg” E. Bermas, Ms. Maritess H. Dimaranan, Mr. Robert V. “Rob” Castañeda, Mr. Joel P. Fatlaunag and Mr. Ronnie Boy R. Lansangan.   

The Balaong River

We left Manila fittingly on April 9, Araw ng Kagitingan, and were picked up, by 5 AM, at the EDSA Shrine by a Lakbay Kalikasan-chartered airconditioned tourist bus.  In all, there were 48 of us from different schools.  Our Lakbay Kalikasan hosts were Ms. Rosa-Vina S. Prudente (Team Leader and Lecturer), Mr. Ryan Viado (Team Leader 1), Mr. Roger Quizol (Team Leader 2), Ms. Hanna Garcia, Mr. Bobby Estrebillo and Mr. Joel Garalde.  We arrived at Biak-na-Bato by 9 AM after a 3-hr. trip (including waiting for latecomers, a stopover for breakfast and calls of nature) via the North Luzon Expressway (NLEX), exiting at Sta. Rita/Baliwag Exit.  Then, from the National Highway, we headed towards Plaridel and Baliwag. At a Y intersection 7 kms. from San Ildefonso, we took the road to the right then,  about 1 km farther, another right at another intersection leading straight to Biak na Bato.

Yungib 2 Cave

This 2,117-hectare National Park, site of Gen. Emilio Aguinaldo’s Biak-na-Bato Republic, covers a large part of San Miguel de Mayumo and parts of San Idelfonso and Doña Remedios Trinidad (DRT).  Its attractions are its series of 16 major caves, some unexplored, that lies at the rocky foothills of the Sierra Madre Mountains. The park is bordered by a small mountain range (the 432-m. high Mt. Nabio, the 422-m. high Mt. Susong Dalaga and the 380-m. high Mt. Silid) in the east and the Balaong River in the west.   It also has low, 140-m. high, rolling hill lands.  Also within the park are Brgys. Biak-na-Bato, Kalawakan and Sibul. The park has two areas: the easily accessible Front Country and the undeveloped and hard to reach Back Country.  

It seemed that we weren’t literally going for a walk in the park as our bus entered the Back Country. There are 3 trails leading to the Back Country and its rarely-visited caves.  The trail we chose was well-marked. It starts directly across the Balaong River from the park entrance and proceeds over hills towards Mt. Silid.  We are to explore several semi-caves and at least one pit cave.  From a trail branch to the top of Bahay Paniki Cave, we can also explore 2 more caves without spelunking gear.

Yungib 1 Cave

Reality meets history at this trail as we were going to walk under the blazing heat of the sun through an unpaved, poorly shaded and dusty trail as our Katipunero ancestors did over a century ago.  No pain, no gain.  However,we had the luxury of doing some stretching exercises before our hike. Accompanying us was park guide Mr. Patricio Garcenilla.  Our nostalgic 2-hr. trek took us to 4 caves – Yungib 2, Yungib 3, Tangapan Cave and Yungib 1. The first 3 were naturally lighted and all had at least 2 entrances.  In every cave, we were given a historical overview of what each cave served.  Yungib 2, the so-called Pagamutan (“infirmary”), was, in the past, the nearest cave from the battlefield. Here, in this makeshift hospital, our Katipunero ancestors sought medical help for battle wounds.  Yungib 3, on the other hand, served as the Katipuneros’ storage for weapons, food and other war necessities.

Tangapan Cave

Tangapan (“meeting place”) Cave, near the third trail’s start, was where Gen. Aguinaldo first made contact with other revolutionaries.  Its well-lit main chamber is accessed by a front and back entrance.  A small tunnel, leading to the river, requires the use of helmets and lights for exploring.  Our final destination, Yungib 1, was the longest and the darkest of the four.  Called the “Ambush Cave,” here our Katipunero ancestors would lie in ambush as they waited for pursuing Spanish soldiers.  They escaped via a rear entrance.  We also made our “escape” via the same route, watching our heads as we groped in the dark.  In all 4 caves, we all said a prayer dedicated to our brave ancestors prior to departing. 

After this nostalgic travel through time, it was back to our bus for a short drive to the developed Front Country.  The parking area before the entrance was filled with food stalls selling just about anything from snacks, maps and even souvenirs made from Biak-na-Bato limestone.  This time, we hiked along paved trails straddling the river to our designated picnic area.  Along the way, we passed (but didn’t explore) the Gen. Aguinaldo Cave and Cuarto-Cuarto Cave. Gen. Aguinaldo Cave, also called Biak-na-Bato Cave, was Aguinaldo’s headquarters in 1897 and site of the republic. The Pact of Biak-na-Bato was also signed here.

Bahay Paniki Cave

Once at the picnic area, we pigged out, kamayan style, on a feast of pork adobo, inihaw na talong (eggplant), tokwa (tofu), rice, and a salad of diced tomatoes, onions and salted eggs, all washed down with soft drinks or bottled water. Just when we felt like dozing off, a whistle blew signaling the start of more trekking.  Whatever we ate seemed to disappear as we traversed the paved, up-and-down (mostly up) trail to Bahay Paniki (“House of Bats”) Cave.  This easy-to-explore and well-lit cave is located upstream from the river.  Probably the largest cave in the area, it has a rather deep natural indoor swimming pool fed by an underground stream.  Thousands of fruit bats fly in and out from dawn and dusk.  The presence of these bats also meant the presence of guano (bat droppings), a sure source of income for the inhabitants.  However, it was a cause of concern for those of us who wanted to swim.  What the heck!  A number of us (including me), with or without life vests, dove in and enjoyed the cool waters.
