Cagayan Valley (Filipino: Lambak ng Cagayan, Ibanag: Tana' nak Cagayan, Ilokano: Tanap ti Cagayan, Itawis: Tanap yo Cagayan, Malaueg: Ga-dang yo Cagayan) is a region of thePhilippines (also designated as Region II or Region 02). It is composed of five provinces: Batanes, Cagayan, Isabela, Nueva Vizcaya, and Quirino. It has four cities: industrial center Cauayan City, its regional center Tuguegarao, its primary growth center and investment hub Ilagan City and its Premier City Santiago City.

Most of the region lies in a large valley in northeastern Luzon, between the Cordilleras and the Sierra Madre mountain ranges. The eponymous Cagayan River, the country's longest, runs through its center and flows out to the Luzon Strait in the north, at the town of Aparri, Cagayan. The Babuyan and Batanes island groups that lie in the Luzon Strait belong to the region.

Cagayan Valley is the second largest region of the Philippines in terms of land area.

Chocolate Hills are a geological formation in Bohol Province, Philippines.^[1] There are at least 1,260 hills but there may be as many as 1,776 hills spread over an area of more than 50 square kilometres (20 sq mi).^[2] They are covered in green grass that turns brown (like chocolate) during the dry season, hence the name.

The Chocolate Hills are a famous tourist attraction of Bohol. They are featured in the provincial flag and seal to symbolize the abundance of natural attractions in the province.^[3] They are in the Philippine Tourism Authority's list of tourist destinations in the Philippines;^[4] they have been declared the country's third National Geological Monument and proposed for inclusion in the UNESCOWorld Heritage List.

Mayon Volcano (Tagalog: Bulkang Mayon, Central Bikol: Bulkan Mayon), also known as Mount Mayon, is an active volcano in the province ofAlbay, on the island of Luzon in the Philippines. Renowned as the "perfect cone" because of its almost symmetric conical shape, the mountain was declared a national park and a protected landscape on July 20, 1938, the first in the country. It was reclassified a Natural Park and renamed Mayon Volcano Natural Park in the year 2000.^[3]

Local folklore refers to the volcano being named after the legendary heroine Daragang Magayon (English: Beautiful Lady)

Mount Pulag is the 3rd highest mountain in the Philippines .^[2] It is Luzon’s highest peak at 2,922 meters above sea level. The borders between theprovinces of Benguet, Ifugao, and Nueva Vizcaya meet at the mountain's peak.

Pasig River (Filipino: Ilog Pasig, Spanish: Río Pásig), is a river in thePhilippines that connects Laguna de Bay to Manila Bay. Stretching for 25 kilometres (15.5 mi), it bisects the Philippine capital of Manila and its surrounding urban area into northern and southern halves. Its majortributaries are the Marikina River and San Juan River.

The Pasig River is technically a tidal estuary, as the flow direction depends upon the water level difference between Manila Bay and Laguna de Bay. During the dry season, the water level in Laguna de Bay is low with the river's flow direction dependent on the tides. During the wet season, when the water level of Laguna de Bay is high, the flow is reversed towards Manila Bay.

The Pasig River used to be an important transport route and source of water for Spanish Manila. Due to negligence and industrial development, the river has become very polluted and is considered dead (i.e., unable to sustain life) by ecologists. The Pasig River Rehabilitation Commission (PRRC), which was established to oversee rehabilitation efforts for the river, is supported by private sector organisations such as the Clean and Green Foundation, Inc. that introduced the Piso para sa Pasig (Filipino: "A peso for the Pasig") campaign in the 1990s.
