Krasny Kluch Spring

Krasny Kluch Spring is located on the left bank of the Ufa River. Before the October Revolution, it was called the White Key (Ak Shishma) due to the whitish color of the water.

In 1965, the spring was recognized as a natural hydrological monument. Krasny Kluch is one of the largest karst springs in the world and the second largest in Europe, on a par with the famous Vaucluse in France.

The spring includes two interconnected karst lakes of a greenish-blue color. The large lake is 190 m long, 170 m wide and up to 38 m deep; the smaller lake is 60 meters long. In total Krasny Kluch covers an area of 3.2 hectares.

The water from the source is a fresh, hydrocarbonate-calcium type. Every day, the spring brings up to 100 tons of dissolved limestone to the surface. The drinking water from the spring is of the highest quality, and is very pure. From the late 1990s, drinking water has been bottled here.

Now a dam and a small hydroelectric power station are built on the spring, and water tourists train and compete here. The source is included in the preliminary list of World Geological Heritage.
