The limestone Ohessaare cliff, on the western shores of the Sõrve peninsula, is around 500 m long and up to 4 m high. It displays the largest cross-section of early Silurian sedimentary rock layers in Ohessaare, Estonia.
The cliff is known for the rock stacks that people have built there. Visitors are encouraged to use the flat stones found on the beach to make their own unique contributions to the landscape. The rocks in the area also contain a lot of fossils.
