14 Highest Mountains in the World

There are only 14 mountains in the world which are over 8,000m / 26,247ft above sea level. They are known as the ‘eight-thousanders’. These mountains are all located in the Himalayan and Karakoram mountain ranges – across Nepal, Tibet (China) and Pakistan.

Climbing to the summit of all 14 eight-thousanders is regarded as a mountaineering challenge and as at 2023 only around 50 mountaineers had achieved this (with more since then). The Himalayan Database captures many of these ascents.

So we created a trekking challenge – to trek to the base camps of all the world’s 14 highest mountains over 8000m – Project Base8000. In itself it’s a challenge of high altitude and logistics, even though we are not climbing to the summits.
