Vidzeme Stony Seashore is located in the Salacgrīva Region and it forms an integral part of the North Vidzeme biosphere nature reserve that includes the 12 kilometres long coastline with an area of 3370 ha. Rare or protected biotypes are found in this territory and hardly ever beyond it. For instance, beaches covered with boulders and pebbles, sandstone exposure on the seashore, white and grey dunes, etc.
Boulders scattered at the coastal underwater part and seashore function as ‘brakes’. When there are strong winds and storms, they reduce the energy of the waves and, hence, also the eroding impact on the shores. Large boulders also cover protruding parts of the seashore or capes, protecting them from washing out. Nature complexes are formed both by natural processes and due to centuries long human activities and they have a great natural value.
Both typical and rare and protected seashore species and biotypes have been found in the stony seashore territory – 31 rare and protected seashore species of flora and fauna. A slightly transformed seashore nature is also a significant resource of tourism and recreation.
Vidzeme Stony Seashore is the only place in the Baltic Sea where sandstone exposures can be seen on the beach. They formed 350–380 million years ago. The largest exposures can be seen to the south from Veczemji (up to 4m high) and from Kāpnieki to Siliņi (5 m high).
