The lake was formed following the abandonment of a granite quarry that subsequently flooded with groundwater.
The water's high transparency and blue-green hue are attributed to the specific chemical composition of the granite and radon-containing minerals.
The quarry walls rise vertically up to 20 meters above the water line in several sections.
During the summer, the lake is a frequent venue for regional and national cliff diving competitions.
The water temperature remains relatively cool throughout the year due to the depth of the basin and underground springs.
Radonove Ozero, also known as the Radon Lake, is a flooded granite quarry located near the village of Myhiya in the Mykolaiv Oblast. The water features a distinct turquoise color due to the high mineral content and the composition of the surrounding granite rocks. The quarry depth reaches approximately 40 meters, making it a popular spot for high-altitude cliff diving and recreational swimming. The surrounding landscape consists of rugged granite cliffs and sparse steppe vegetation. It is part of the Buzkyi Hard National Nature Park territory. The site is a prominent feature of the Southern Bug river valley's geological landscape.
The highest northern ridge overlooking the water provides the best panoramic view of the lake's turquoise color contrast against the grey granite.
Wear water shoes, as the perimeter is dominated by sharp granite rocks rather than sand.
Bring your own shade structures, as there is almost no natural tree canopy surrounding the cliff edges.
Pack a basic first aid kit, as the rocky terrain can be difficult to navigate safely.
Avoid jumping from the cliffs unless you are an experienced diver, as there are hidden underwater rock ledges.
Practice 'leave no trace' principles, as this is a natural site without formal waste management services.
