Lake Ulzhay

Lake Ulzhay is a salt lake and protected natural area in Sakhalin Oblast with extremely high mineral concentrations in its waters. These salt levels fundamentally shape which plants and animals can exist in and around the lake.

The lake received protected status as part of Russia's environmental conservation efforts, marking a shift in how the region managed its natural resources. This designation represented an important decision to preserve the area for the long term.

Local people have long observed the seasonal shifts in water and wildlife around this salt lake, and these practices remain part of their connection to the land. The way residents interact with the lake reflects their understanding of its rhythms and importance as a natural landmark.

Visiting the lake requires permission from regional authorities and special vehicles suited to the challenging terrain surrounding it. Planning ahead with local officials and bringing appropriate gear is essential for a safe visit.

The waters support microorganisms that thrive in extremely salty conditions, sometimes turning the surface red-pink during certain seasons. This visible transformation makes it a rare example of an extreme aquatic environment.
