Callao Cave was visited by American Governor-General Theodore Roosevelt, Jr. in 1932 who under his term created the National Park system of the country with the passing of Act No. 3195 in 1932. Callao Cave was one of the earliest national parks of the country when it was established on July 16, 1935, by Proclamation no. 827. The "Callao Cave National Park" encompassed an area  of of land. With the passing of the NIPAS Act of 1992 that revamped the protected areas of the country, the Callao National Park was reclassified but enlarged by Proclamation no. 416 on June 29, 1994. The protected area was reestablished as the "Peñablanca Protected Landscape". In 2003 upon the recommendation of the Department of Environment and Natural Resources (DENR), the protected area was further enlarged to include certain parcels of land in the public domain. Proclamation 416 no. was amended by Proclamation no. 484, signed by President Arroyo on October 6, 2003. The law enlarged the park to and  renamed as the Peñablanca Protected Landscape and Seascape (PPLS). The protected area is particularly described as bounded on the North and East of Public Forest under FR-1011 per Proclamation No. 584 dated July 8, 1940; on the South by Callao Reforestation Project and on the West by Block I, Alienable and Disposable of Cagayan Project No. 13-C, Certified on February 27, 1923. Since June 22, 2018, the protected area has been designated as a national park through the Expanded National Integrated Protected Areas System (ENIPAS) Act or Republic Act No. 11038 which was signed by President Rodrigo Duterte. Description . The Peñablanca park is situated just east of Cagayan's provincial capital of Tuguegarao and some 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. Tourism. The Callao Cave Eco-Tourism Zone is being promoted by the locals as the 'Caving Adventure Capital of the Philippines' since it has more than 300 caves including the mother Callao Cave. To accelerate the development of the Callao Cave ETZ, the Provincial  Tourism Office of Cagayan has tied up with several Non-Government Organizations (NGOs) such the Sierra Madre Outdoor Club (SMOC), Cagayan visitors bureau, souvenir makers, and other interested investors to help make Callao Caves tourist zone more develop and beautiful. One of the projects they established with Cagayan visitors bureau is the establishment of a visitor center at the cottage area. The SMOC also assists tourists in recreational activities like caving, spelunking, mountain climbing, trekking, kayaking, rappelling, swimming, circadian flight viewing, and picnicking. The group also offers their facilities for tourism whenever needed, such as the souvenir makers display souvenir  items at the cave site. The Department of Tourism also gave a boat and a floating picnic house to the residents of the place for a livelihood. The office also augmented the trainings and seminars conducted by the provincial tourism office to the tourist guides, guards, and personnel manning the zone. The tourism office staff were also arranging some partnerships with other organizations and agencies to rebuild the deteriorating facilities of the Callao Caves cottages for trainings, seminars, conventions, and other uses. As of 2013, the Callao Caves Resort located across Pinacanauan River from the caves, is the only accommodation  available in the Callao Cave Tourism Zone. Caves. Callao Cave.
