Angono Petroglyphs in Binangonan

Petroglyphs (also called rock engravings) are pictogram and logogram images created by removing part of a rock surface by incising, picking, carving, and abrading. Outside North America, scholars often use terms such as "carving", "engraving", or other descriptions of the technique to refer to such images. Petroglyphs are found world-wide, and are often associated with prehistoric peoples. The word comes from the Greek words petro-, theme of the word "petra" meaning "stone", and glyphein meaning "to carve", and was originally coined in French as pétroglyphe. [Source: Wikipedia]

After a hearthy lunch, we proceeded to Angono Petroglyphs.  Again, we followed the signs to Thunderbird Resort.  The road here is uphill.  When we got there, instead of taking a right to Thunderbird, we continued on the main road, passing a firing range and a botanical garden/restaurant on the left side.  The entrance is on an alley on the left, right after the garden/restaurant, be on the lookout for a tunnel.

Going out of the tunnel, we followed the path and it led us to the site museum.

The Angono Petroglyphs Site Museum is situated at the municipality of Binangonan, province of Rizal, three and a half kilometers southeast of the town of Angono. It was discovered in 1965 by National Artist, Carlos “Botong” Francisco during a field trip with a troop of boy scouts. He reported to the National Museum the existence of a cave with drawings of a primitive quality. [Source]

They've placed a small museum here that contains some "artifacts" and information about the petroglyphs and the place.  This is also where paid for the entrance fee (PhP20.00 for adults; PhP10.00 for students).

The "cave" is a few steps up from the museum.  They've already placed a platform so that it can be saved from vandals.

I think we stayed here for 30 minutes (or maybe less) but it was worth it.  It's a unique experience not far from the city.  However, I guess for now, only those with private transportation have access to it.
