The lake surface sits at approximately 60 meters above sea level, meaning the lake floor is actually below sea level.
Wast Water was voted 'Britain's Favourite View' in a 2007 ITV poll.
The lake is owned by the National Trust.
Its exceptionally clear water is a result of low nutrient levels, which prevents significant algal growth.
The lake is fed primarily by the River Lingmell, Mosedale Beck, and Over Beck.
The scree slopes on the southeast side are among the largest in the UK.
Wast Water is a glacial lake located within the Lake District National Park in Cumbria, England. It holds the record as the deepest lake in England, reaching a maximum depth of 79 meters. The lake is situated in the remote Wasdale valley and is framed by the peaks of Scafell Pike, Great Gable, and Lingmell. The lake basin was formed by glacial erosion during the last ice age. The water is oligotrophic, meaning it has very low nutrient content and exceptional clarity. The surrounding terrain is characterized by scree slopes, most notably the Great Gable screes that descend directly into the water. The area is part of a designated Site of Special Scientific Interest due to its geological features. There is a single road running along the northwestern shore providing access to the valley head. The lake is frequently used for low-impact recreation such as swimming and kayaking.
The western shoreline near the National Trust car park provides a clear vista of the lake aligned with the Great Gable peak.
Bring sturdy, waterproof hiking boots, as the shoreline path consists of uneven rocks and scree.
Be prepared for rapidly changing weather conditions characteristic of high-altitude mountain environments.
Carry a physical map and compass, as mobile signal is non-existent throughout much of the Wasdale valley.
Attempting to drive large campervans or motorhomes up the narrow, steep roads leading to the valley.
Practice 'Leave No Trace' principles, keep dogs on leads to protect local sheep and wildlife, and avoid disturbing the fragile scree slopes.
