The lake's original name, Pyhäjärvi, translates from Finnish as 'Sacred Lake'.
The lake reaches depths of up to 28 meters in its northern section.
It is a popular site for historical exploration due to the presence of submerged Finnish structures from the mid-20th century.
The island of Cherny was formerly known as 'Suvisaari' during the period of Finnish sovereignty.
The water clarity allows for visibility reaching up to 3-4 meters in favorable conditions.
Otradnoye Ozero, formerly known as Pyhäjärvi, is one of the largest freshwater lakes in the Priozersky District of the Leningrad Oblast, covering approximately 72 square kilometers. The lake is characterized by its high water transparency and complex coastline featuring several islands, the largest of which is Cherny Island. It serves as a significant hub for recreational fishing, hosting species such as perch, pike, roach, and bream. The lake is fed by several smaller rivers, including the Pchelinka, and drains into the Volchya River. Dense coniferous forests, primarily pine and spruce, dominate the surrounding shoreline, creating a classic taiga landscape. The water level is regulated by a small dam near the village of Otradnoye, which impacts local hydrological flow. Historically, the area was part of the Karelian Isthmus and contains remnants of pre-1940 settlement patterns.

Bring specialized insect repellent, as the surrounding forest areas have high mosquito and tick activity during summer months.
If planning to explore by water, note that weather conditions can shift rapidly, creating strong winds on open sections of the lake.
Ensure you have a GPS-enabled map, as the dense forest trails around the perimeter lack consistent signage.
Do not attempt to cross to islands without a sturdy, equipped boat, as local currents and underwater boulders are hazardous for inflatable craft.
Access may be restricted by snow and ice buildup on unpaved access roads during winter months.
Practice 'Leave No Trace' principles; do not light open fires in the forest during high fire-risk periods.
