13 hours trip from my home province, we reached Callao Caves on April 23,2014.
Callao Cave is one of the limestone caves located in the Municipality of Peñablanca, Cagayan province, in the Philippines. The seven-chamber show cave is one of 300 caves that dot the area and the best known natural tourist attractions of the province. The town is named as Peñablanca (Spanish for white rocks) for the presence of white limestone rocks in the area. Callao Cave is located in the Barangays of Magdalo and Quibal in Peñablanca about 24 km (15 mi) northeast of Tuguegarao City, the capital of the Province of Cagayan.
Callao Cave is the premier attraction in the Peñablanca Protected Landscape and Seascape. It is the most accessible of all the caves, its entrance is reached by climbing 184 concrete steps.
The first chamber of the show cave is the largest room with a width of about 50 m (160 ft) and a height of 36 m (118 ft). The cathedral-like room has been turned into a chapel by the local people. A rock formation serves as the altar of the chapel lit by a stream of light coming from a rooftop opening. The conditions inside the caves have caused the formation of stalactites and stalagmites, more so in the deeper chambers. Several spectacular speleothems or formations are found inside the cave like flowstones, glittering dripstones, cave curtains, crystal helictites, columns, etc.
