Europe's highest mountain: Elbrus or Mont Blanc?
Elbrus or Mont Blanc? The answer depends not on the mountains but on where the line between Europe and Asia is drawn. Here are the two boundaries, the summits and why both answers exist.
Europe's highest mountain is Elbrus, 5,642 metres, if the boundary with Asia runs along the main ridge of the Caucasus. Draw it further north and the whole Caucasus falls in Asia, and the answer becomes Mont Blanc, a little over 4,800 metres. Both answers appear in atlases and encyclopaedias.
It sounds like a question of fact, but it is a question of definition. The mountains stay put. It is the continental boundary that moves, depending on who draws the map.
Elbrus: a volcano with two summits
Elbrus stands in the western Caucasus in Russia, a little over ten kilometres north of the main ridge and the border with Georgia. It is a stratovolcano with two summits. The western one is higher at 5,642 metres, the eastern one reaches 5,621. It has not erupted in roughly 2,000 years.
The lower eastern summit was climbed first, in 1829, by Khillar Khachirov, a guide for a Russian expedition. The higher western summit was reached in 1874 by a British party led by F. Crauford Grove, with the Swiss guide Peter Knubel.
The height varies slightly between sources. The Norwegian encyclopaedia Store norske leksikon gives 5,642 metres in its entry on the mountain and 5,633 in its entry on Europe. That says less about the mountain than about how heights get copied from different surveys.
Where does Europe end?
In the east the boundary is fairly uncontroversial: the Ural Mountains and the Ural River down to the Caspian Sea. That the Urals became the line has a Swedish connection. It was Philip Johan von Strahlenberg, a Swedish officer held as a prisoner of war in Siberia after the battle of Poltava, who in the 1720s proposed the Urals instead of the ancient boundary at the river Don.
Between the Black Sea and the Caspian it gets difficult. There are two main lines.
The Caucasus watershed. The boundary follows the main ridge of the Greater Caucasus. Elbrus lies north of the ridge and ends up in Europe. This is the line used by, among others, National Geographic and the CIA World Factbook, and the most common today.
The Kuma-Manych Depression. A low trough north of the mountains, between the Sea of Azov and the Caspian. On this line the whole Caucasus falls in Asia. It is the boundary the Geographical Society of the USSR recommended for school textbooks in 1958.
On the second line Mont Blanc becomes Europe's highest mountain, because nothing else in Europe comes close.
Mont Blanc: highest in the Alps and in the EU
Whichever boundary you use, Mont Blanc is the highest mountain in the Alps, in Western Europe and in the EU. Exactly how high is a story of its own: the summit is a snow dome that is surveyed regularly, and the figure moves. The most recent published survey, from 2023, gave 4,805.59 metres, while the maps still say 4,810. According to the organisers, results from the 2024-2026 surveys are due to be presented on 14 October 2026. The full story is in How high is Mont Blanc?
The summit on the line
The watershed produces a curiosity of its own. Shkhara, around 5,200 metres and Georgia's highest mountain, sits right on the main ridge, one side in Russia and the other in Georgia. If the watershed is the continental boundary, the summit stands on the line between Europe and Asia. Anyone asking for Europe's highest mountain outside Russia does not get a clean answer either.
So which answer is right?
Both, on different assumptions. The most common boundary today gives Elbrus, and Elbrus is the peak on the Seven Summits list of the highest point on each continent. Someone who says Mont Blanc is not wrong, just using a different map. The honest answer is one sentence longer: Elbrus, if the Caucasus counts as Europe, otherwise Mont Blanc.
That applies to more mountain heights than you might think. They are an agreement as much as a measurement, which we cover in How a mountain's height is measured.
Alpine summits for the wall
We have not made Elbrus. From the Alps there is Mont Blanc, the Matterhorn with Zermatt and Cervinia in the same frame, and Jungfrau with the Eiger and the Mönch. Why the Matterhorn looks the way it does is explained in The Matterhorn: why the mountain has exactly four faces. If you want a different mountain, you can choose the area yourself in FRMD By You.
