Lowest Points on Land


The Lowest Places Below Sea Level on Each Continent

Lowest Point in the World (and Asia)
Dead Sea shore, Israel-Jordan: 1369 feet / 417.5 meters below sea level

Lowest Point in Africa

Lake Assal, Djibouti: 512 feet / 156 meters below sea level

Lowest Point in Australia

Lake Eyre: 52 feet / 12 meters below sea level

Lowest Point in Europe

Caspian Sea shore, Russia-Iran-Turkmenistan, Azerbaijan: 92 feet / 28 meters below sea level

Lowest Point in Western Europe

Tie: Lemmefjord, Denmark and Prins Alexander Polder, Netherlands: 23 feet / 7 meters below sea level

Lowest Point in North America

Death Valley, California: 282 feet / 86 meters below sea level

Lowest Point in South America

Bahia Blanca, Argentina: 138 feet / 42 meters below sea level

Lowest Point in Antarctica

The Bentley Subglacial Trench is approximately 2540 meters (8,333 feet) below sea level but is covered with ice; if Antarctica's ice were to melt, exposing the trench, it would be covered by sea so it is a quasi-lowest point and if one ignores the reality of the ice, it is the lowest point "on land" on the earth.
