Seven Summits

The Seven Summits are the tallest mountains on each continent. The summits are:

• , Asia, 8,848 m
• , South America, 6,961 m
• , North America, 6,194 m
• , Africa, 5,895 m
• , Europe, 5,642 m
• , Antarctica, 4,892 m

Australia's tallest mountain, (2,228 m), was on the original Seven Summits list. As this mountain is considered a rather trivial challenge, on New Guinea (4,884 m) is considered to represent Oceania.
(4,810 m) is occasionally regarded as Europe's tallest mountain, as Elbrus, and nearby peaks, are on different sides of the Europe-Asia border, depending on definition. However, the mountain is not on any of the Seven Summits lists. It is however a classic in mountaineering, and an alternative to Elbrus, due to the often unstable political situation in the North Caucasus.

Some mountaineers attempt to climb the second highest peak on each continent. While the peaks are at lower altitudes than the Seven Summits, some of them are more technically difficult, so the Second Summits are considered a greater mountaineering challenge than the Seven Summits.

• , Asia, 8,611 m
• , South America, 6,893 m; highest volcano of the Earth
• , North America, 5,959 m
• , Europe, 5,205 m
• , Africa, 5,199 m
• , Antarctica, 4,852 m

Once again, there's some disagreement about the seventh mountain on the list. If you prefer a mountain in Australia, it's (2,209 m); otherwise, it's (4,760 m) in Indonesia.
Those who consider Mont Blanc the tallest mountain in Europe would consider (4,634 m; Switzerland's tallest mountain) to be the second tallest.
