If we were to measure by peak height above sea level then starting with Mount Everest all 25 of the tallest mountains in the world would be in the Himalayas. The problem with doing that, however, is that the dividing line between a mountain with multiple peaks and separate mountains is not always clear. For this reason a better measurement to use is called “topographic prominence” (basically how much the mountain sticks out from the surrounding landscape). So, while Mount Kilimanjaro’s peak is not as far away from sea level as any number of peaks in the Himalayas, the difference between its base and its peak is much greater. With that in mind these are the 25 tallest mountains in the world.
Mount Kinabalu is a prominent mountain on the island of Borneo in Southeast Asia. It is located in the East Malaysian state of Sabah and is protected as Kinabalu National Park, a World Heritage Site.
Namcha Barwa or Namchabarwa is a mountain in the Tibetan Himalaya. The traditional definition of the Himalaya extending from the Indus River to the Brahmaputra would make it the eastern anchor of the entire mountain chain, and it is the highest peak of its own section as well as Earth’s easternmost peak over 7,600 metres.
Bogda Peak or Bogda Feng is the highest mountain in the Bogda Shan range, in the eastern Tien Shan mountains, China, at 5,445 m (17,864 ft).
Chimborazo is a currently inactive stratovolcano located in the Cordillera Occidental range of the Andes. Its last known eruption is believed to have occurred around 550 AD and with a peak elevation of 6,268 metres (20,564 ft), Chimborazo is the tallest mountain in Ecuador.
Jengish Chokusu is the highest mountain in the Tian Shan mountain system at 7,439 metres (24,406 ft). It lies on the Kyrgyzstan–China border southeast of lake Issyk Kul.
