Ontika Cliff, Limestone cliff in Toila Rural Municipality, Estonia
Ontika Cliff is a limestone formation on the coast of Toila Rural Municipality that rises 55 meters above sea level and contains multiple geological layers. The vertical wall shows distinct rock patterns and was shaped by sediment accumulation over millions of years.
This limestone formation developed through marine sediment deposition during different geological periods, creating its characteristic layered structure. The processes that shaped this feature are closely tied to the geological development of the Baltic region.
The name comes from an Estonian word referring to slate formations. Locals and visitors use the viewing areas to observe the raw coastal landscape and trace the visible layers in the rock face.
An observation point near Valaste Waterfall provides year-round access to view the cliff and surrounding coastal landscapes. The area is open for exploration and easy to navigate, but visitors should wear appropriate clothing for changeable weather.
This cliff is part of a limestone bank stretching about 1100 kilometers from Sweden's Öland Island to Lake Ladoga in Russia. This geological formation extends across several countries and shows the connected structure of the Baltic landscape.
