The lake was formed as a direct result of industrial sand extraction which left a deep, water-filled depression in the local topography.
The high mineral content of the soil and water contributes to the distinct blue-green color of the lake basin.
The site experiences significant erosion due to its sandy composition, leading to changing trail paths year over year.
Due to the steepness of the surrounding banks, the water depth increases rapidly from the shoreline.
Kar'yer is a former sand quarry located near Toksovo, transformed into a popular recreational area characterized by its steep, sandy cliffs and a deep, clear lake. The basin features significant elevation changes that provide panoramic views of the surrounding pine forest landscape. The lake is fed by groundwater, resulting in high water transparency. The site is a rugged, unmaintained natural area lacking formal park infrastructure, trails, or lifeguard services. It is frequented by local hikers, swimmers, and those seeking terrain for off-road cycling. The soil composition is primarily loose sand, which requires careful navigation on steep inclines.

Wear sturdy, closed-toe hiking shoes with good grip to manage the loose, sandy slopes.
Bring your own waste disposal bags, as there are no bins or maintenance services provided on-site.
Avoid entering the water if you are not a confident swimmer, as the sudden drop-offs and cold springs are common hazards.
Do not attempt to drive motorized vehicles down the sandy banks, as they frequently become stuck in the loose terrain.
Accessible year-round, though roads leading to the entrance may become difficult to traverse during heavy winter snowfall or spring thaw.
Practice 'Leave No Trace' principles by removing all trash; avoid digging or disturbing the unstable sandy cliff faces.
