The Puerto Princesa Subterranean River National Park is a protected area of the Philippines located about 80 kilometres (50 mi) north of the city centre of Puerto Princesa, Palawan. The river is also called Puerto Princesa Underground River. The national park is located in the Saint Paul Mountain Range on the western coast of the island. It is bordered by St. Paul Bay to the north and the Babuyan River to the east. The City Government of Puerto Princesa has managed the National Park since 1992. The entrance to the subterranean river is a short hike or boat ride from the town Sabang.

In 2010, a group of environmentalists and geologists discovered that the underground river has a second floor, which means that there are small waterfalls inside the cave. They also found a cave dome measuring 300 m (980 ft) above the underground river, rock formations, large bats, a deep water hole in the river, more river channels, and another deep cave, as well as marine creatures and more. Deeper areas of the underground river are almost impossible to explore due to oxygen deprivation.

On November 11, 2011, Puerto Princesa Underground River was provisionally chosen as one of the New7Wonders of Nature. This selection was officially confirmed on January 28, 2012.

Jejudo (also known as Jeju Island) is a volcanic island. With a surface area of 1,846 sqkm it is the largest island 130 km off the coast of the Korean Peninsula, and the main island of Jeju Province of South Korea. The island lies in the Korea Strait, southwest of South Jeolla Province. The island contains the natural World Heritage Site Jeju Volcanic Island and Lava Tubes. A central feature of Jeju is Hallasan, the tallest mountain in South Korea and a dormant volcano, which rises 1,950 m above sea level. 360 satellite volcanoes are around the main volcano.

The island was created entirely from volcanic eruptions approximately 2 million years ago, during the time period extending from the Tertiary to the beginning of the Quaternary period, and consists chiefly of basalt and lava. The eruptions took place in the Cenozoic era. It has a humid subtropical climate, warmer than that of the rest of Korea, with four distinct weather seasons. Winters are cool and dry while summers are hot, humid, and sometimes rainy.

Iguazu Falls, Iguazú Falls, Iguassu Falls, or Iguaçu Falls (Spanish: Cataratas del Iguazú [kataˈɾatas ðel iɣwaˈsu]; Guarani: Chororo Yguasu [ɕoɾoɾo ɨɣʷasu]; Portuguese: Cataratas do Iguaçu [kataˈɾatɐʒ du iɡwaˈsu]) are waterfalls of the Iguazu River on the border of the Argentine province of Misiones and the Brazilian state of Paraná. They are the largest waterfalls system in the world. The falls divide the river into the upper and lower Iguazu. The Iguazu River rises near the city of Curitiba. For most of its course, the river flows through Brazil, however, most of the falls are on the Argentine side. Below its confluence with the San Antonio River, the Iguazu River forms the boundary between Argentina and Brazil.

The name “Iguazu” comes from the Guarani or Tupi words “y” [ɨ], meaning “water”, and “ûasú “[waˈsu], meaning “big”. Legend has it that a deity planned to marry a beautiful woman named Naipí, who fled with her mortal lover Tarobá in a canoe. In a rage, the deity sliced the river, creating the waterfalls and condemning the lovers to an eternal fall. The first European to record the existence of the falls was the Spanish conquistador Álvar Núñez Cabeza de Vaca in 1541.

Hạ Long Bay (Vietnamese: Vịnh Hạ Long,  listen, literally: “descending dragon bay”) is a UNESCO World Heritage Site and popular travel destination in Quảng Ninh Province, Vietnam. Administratively, the bay belongs to Hạ Long City, Cẩm Phả town, and is a part of Vân Đồn District. The bay features thousands of limestone karsts and isles in various shapes and sizes. Hạ Long Bay is a center of a larger zone which includes Bái Tử Long Bay to the northeast, and Cát Bà Island to the southwest. These larger zones share a similar geological, geographical, geomorphological, climate and cultural characters.

Hạ Long Bay has an area of around 1,553 km2, including 1,960–2,000 islets, most of which are limestone. The core of the bay has an area of 334 km2 with a high density of 775 islets. The limestone in this bay has gone through 500 million years of formation in different conditions and environments. The evolution of the karst in this bay has taken 20 million years under the impact of the tropical wet climate. The geo-diversity of the environment in the area has created biodiversity, including a tropical evergreen biosystem, oceanic and sea shore biosystem. Hạ Long Bay is home to 14 endemic floral species and 60 endemic faunal species.

Historical research surveys have shown the presence of prehistorical human beings in this area tens of thousands years ago.

Table Mountain (Khoikhoi: Hoerikwaggo, Afrikaans: Tafelberg) is a flat-topped mountain forming a prominent landmark overlooking the city of Cape Town in South Africa, and is featured in the Flag of Cape Town and other local government insignia. It is a significant tourist attraction, with many visitors using the cableway or hiking to the top. The mountain forms part of the Table Mountain National Park.

The main feature of Table Mountain is the level plateau approximately 3 kilometres (2 mi) from side to side, edged by impressive cliffs. The plateau, flanked by Devil’s Peak to the east and by Lion’s Head to the west, forms a dramatic backdrop to Cape Town. This broad sweep of mountainous heights, together with Signal Hill, forms the natural amphitheatre of the City Bowl and Table Bay harbour. The highest point on Table Mountain is towards the eastern end of the plateau and is marked by Maclear’s Beacon, a stone cairn built in 1865 by Sir Thomas Maclear for trigonometrical survey. It is 1,086 metres (3,563 ft) above sea level, about 19 metres (62 ft) higher than the cable station at the western end of the plateau.

The cliffs of the main plateau are split by Platteklip Gorge (“Flat Stone Gorge”), which provides an easy and direct ascent to the summit and was the route taken by António de Saldanha on the first recorded ascent of the mountain in 1503.
