context_page_description: The Peñablanca Protected Landscape and Seascape is a protected area and national park in Peñablanca, Cagayan. It is on the border with Isabela province, contiguous with the Northern Sierra Madre Natural Park. The protected area, best known as the location of Callao Cave, covers the largest block of forest under conservation in the province. It covers 118,781.582 hectares of the northern Sierra Madre mountain range and its adjacent Pacific coast.
  The protected area is home to the Callao Cave Eco-Tourism Zone being promoted by the locals as the 'Caving Adventure Capital of the Philippines'. More than 300 caves dot the protected area, 75 of which have been documented by the National Museum since 1977. The area is easily accessible by automobile.
context_section_description: The Peñablanca park is situated just 24 kilometres (15 mi) east of Cagayan's provincial capital of Tuguegarao and some 580 kilometres (360 mi) north of Manila. It extends along the northern Sierra Madre range from the Twin Peaks south to Mount Cetaceo towards the border with Isabela. It covers 18 of the 24 barangays of Peñablanca, namely, Callao, San Roque, Cabbo, Nannarian, Malibagbag, Quibal, Agugaddan, Lapi, Nanguilattan, Nabbabalayan, Buyon, Mangga, Minanga, Sisim, Bugatay, Bical, Baliuag and Cabasan.
  The park is well known for its numerous limestone formations found within its 300 cave systems, the most popular of which are Callao Cave and Sierra Cave. It is traversed by the Pinacanauan River, a major tributary of the Rio Grande de Cagayan, which supplies clean water and irrigation to surrounding communities as well as the nearby city of Tuguegarao. The park is inhabited by three indigenous groups, namely the Ibanag, Itawes and Aeta. It is also known for its archaeological relics discovered within its caves.
