World’s Deepest Lakes

World’s Deepest Lakes

From the hauntingly clear waters of Siberia's Lake Baikal to the mysterious subglacial realm of Antarctica's Lake Vostok, here is the list of the world's deepest lakes.

1/10 Lake Baikal - 1642 metres

Lake Baikal - 1642 metres

Lake Baikal, located in Siberia, Russia, is the world's deepest freshwater lake. Its maximum depth reaches an astonishing  1642 meters (5,387 feet), making it the deepest lake on the planet. Known for its exceptional clarity and unique biodiversity, Lake Baikal contains about 20% of the world's unfrozen freshwater reserve. The lake's depth is a testament to its geological history, formed within a tectonic rift zone. Baikal's deep and pristine waters make it a natural wonder and a UNESCO World Heritage Site.

2/10 Lake Tanganyika - 1470 metres

Lake Tanganyika - 1470 metres

Lake Tanganyika, situated in East Africa and shared by Tanzania, the Democratic Republic of the Congo, Burundi, and Zambia, ranks as the second-deepest freshwater lake globally. It has a maximum depth of approximately 1470 meters (4823 feet). Its depth is a result of tectonic activity, as the East African Rift stretches beneath it. Beyond its ecological significance, Lake Tanganyika holds cultural importance for the surrounding communities and stands as one of Africa's Great Lakes, contributing to the continent's natural heritage.

3/10 Caspian Sea - 1025 metres

Caspian Sea - 1025 metres

The Caspian Sea, the world's largest inland body of water, is a unique endorheic basin bordered by five countries: Russia, Kazakhstan, Turkmenistan, Iran, and Azerbaijan. Despite its name, it is technically a lake. The Caspian Sea's maximum depth reaches about 1025 metres (3363 feet), making it the third deepest lake globally. 

4/10 Lake Vostok - 900 metres

Lake Vostok - 900 metres

Lake Vostok is a large subglacial lake located beneath the East Antarctic Ice Sheet, about 4,000 meters below the surface of the ice. This makes it the deepest known freshwater lake in the world. It is estimated to be roughly 250 kilometers long and 50 kilometers wide, with an average depth of 900 meters (2950 feet). The lake was discovered in 1970 by Russian scientists conducting an aerial survey of the area and was named after the Russian research station Vostok, located nearby. Despite its significant depth, the lake is filled with fresh water, likely originating from precipitation and glacial meltwater. The lake has been isolated from contact with the atmosphere for some 15 million years, resulting in a unique and largely undisturbed environment. This environment has led to speculation that Lake Vostok may be home to some form of microbial life. 

5/10 O'Higgins-San Martín Lake - 836 metres


O’Higgins/San Martín Lake, also known as General Carrera Lake, is a stunning glacier-fed lake in Patagonia. Located in the Aysén Region of Chile and Argentina, it is the largest lake in South America and the second-largest in the Southern Hemisphere. It is also the deepest lake in South America, with a maximum depth of 836 meters (2742 feet). The lake was created by a powerful earthquake in 1960 that caused the retreat of the Northern Patagonian Ice Field, revealing a huge valley that filled with water to form the lake. The lake is named after the Chilean and Argentinian revolutionary, Bernardo O'Higgins and José de San Martín, who fought for the independence of Chile and Argentina respectively. The lake is of immense beauty, with its turquoise waters, snow-capped mountains, and lush forests. It is a very popular destination for tourists, as it offers a variety of activities such as fishing, kayaking, and sailing.

6/10 Lake Malawi - 706 metres

Lake Malawi - 706 metres

Lake Malawi, located in Southeast Africa, is one of the deepest lakes on the continent. It has a maximum depth of 706 meters (2316 feet) , making it the sixth deepest lake in the world. It is located in the Great Rift Valley and is surrounded by the countries of Malawi, Mozambique, and Tanzania. The lake's large size and deep depths make it an important source of fresh water in the region. It covers an area of over 70,000 square kilometers. 

7/10 Issyk Kul - 668 metres

Issyk Kul - 668 metres

Lake Issyk-Kul is a large lake located in the Issyk-Kul region of Kyrgyzstan. It is one of the deepest and largest lakes in Central Asia, with a maximum depth of 668 meters (2192 feet).
