The Tallest Mountains in the World

At 8,848 m (29,035 feet), Mount Everest is the tallest mountain in the world.

All 10 of the world's tallest summits are found in central and southern Asia. They are measured as individual peaks and not as part of mountain ranges.

Technically, Mauna Kea, a dormant partially submerged volcano found on the island of Hawaii, is the world's tallest mountain if measured from the floor of the Pacific Ocean to its peak for a total distance of 10,203 m. However, for the purpose of this list, we will only be looking at mountains whose base is found above sea level, i.e. both the top and the bottom of the mountain must be above sea level.

10. Annapurna I (8,091 m)

Annapurna I is the world's tenth tallest peak, at 8,091 m high. It is found in north-central Nepal. Like most other mountains of its grandeur, Annapurna has a reputation for being extremely difficult to climb. In fact, it boasts the highest climbing attempt to fatality ratio of any other major mountain on earth. Approximately 32% of climbers who make an attempt to reach the summit of Annapurna I perish. There are few mountains that are more difficult to climb.

9. Nanga Parbat (8,126 m)

Ninga Parbat is the world's highest point. It is found in Pakistan in the western section of the Himalayas. It is considered to be one of the world's eight-thousanders, that is, mountains that measure over 8,000 metres. Despite its extreme height, Nanga Parbat is still only the second tallest mountain in Pakistan, a country of major peaks.

8. Manaslu (8,163)

Manslu is the world's eighth highest point. It is in the Manaslu Himalaya range and the first ascent was made in 1956 by Norbu and Imanishi. The mountain has since been climbed just under 300 times. It is considered to be one of the world's deadliest summit treks. It is located in Nepal.

7. Dhaulagiri I (8,167 m)

Seventh on the list is Dhaulagiri I, which rises to a height of 8,167 m. The first ascent was made in 1960 by Diemberger, Nawang Dorje, Nyima Dorje, Forrer, and Schelbert. Found in Nepal, Dhaulagiri I is known for its imposing presence over the Kali Gandaki Valley, one of the Earth's deepest gorges.

6. Cho Oyu (8,188 m)

The sixth tallest mountain the world is Cho Oyu, located in the Mahalangur Himalaya range near the border between China and Nepal. It rises to 8,188 meters above sea level. The first ascent was made in 1954 by Tichy, Lama, and Jochler, and today guided tours to the top of the mountain are available. It is considered the easiest to climb of all eight-thousanders - with "easy" being relative, of course!

5. Makalu (8,485 m)

At 8,485 m, Mount Makalu is the fifth tallest mountain in the world. Makalu is perhaps most notable for its pyramid-shaped peak. It is considered to be one of the most difficult mountains to climb. Like others on this list, Makalu is found where China (Tibet) and Nepal meet. In China, the mountain is called Makaru.

4. Lhotse (8,516 m)

Mount Lhotse is the fourth highest mountain in the world. It was first ascended in 1956. It is found not too far away from its very famous neighbor of Mount Everest. In fact, Lhotse and Everest are connected by a ridge called South Col.

3. Kangchenjunga (8,586 m)

The third tallest mountain in the world is Mount Kangchenjunga. The mountains raises 8,586 m into the sky and straddles the border between India and Nepal. Kangchenjunga is located around 125 km away from Mount Everest and is a part of the Himalayan range. It was previously believed that Mount Kangchenjunga was the tallest mountain in the world, before more accurate measurements were gathered.


2. K2 (8,611 m)

Mount K2, the second highest mountain the world, is found in the Baktoro Karakoram range in northern Pakistan on the border with China. K2 is extremely difficult and hazardous to climb and it is impossible to climb the mountain during the winter. Prior to the first successful climbing of K2 in 1954, it was previously believed that it was not humanly possible to ascend the mountain.

1. Mount Everest (8,848 m)

At a staggering 8,848 m or 29,035 feet above sea level, Mount Everest is the tallest mountain in the world. Not only the world's highest mountain but perhaps also the world's most famous mountain, Mount Everest is also known as Sagarmatha and Chomolungma in the native Himalayan tongue. It is in the Mahalangur Himalaya range and is estimated to be tens of millions of years old.

Although the climbing of Mount Everest is a popular goal held by mountain enthusiasts, it is actually an extremely dangerous endeavour. In fact, since the time of its first recorded successful ascent in 1924, nearly 300 people have died climbing the mountain. Not only are conditions on the mountain extremely windy and frigid, with temperatures reaching -80 degrees Fahrenheit, but climbers are also susceptible to altitude sickness. This makes Mount Everest not only the tallest mountain in the world, but also the world's most dangerous.
