Three Brothers Islands, Protected island group in Sakhalin Oblast, Russia.
Three Brothers Islands is a group of three small rocky islands in the Strait of Tartary, off the coast of Sakhalin Oblast in the Russian Far East. The islands rise steeply from the sea and form a row of stone formations that stand out clearly along the coastline.
The islands were designated as a natural monument during the Soviet period to protect their geological formations. This protected status was kept after the end of the Soviet Union and remains in place today.
Local fishers use the islands as natural reference points when crossing the strait. Their outline has been a familiar sight for generations of coastal communities in the region.
A visit to the islands requires a permit from Russian authorities, as they are a protected area. It is worth starting the request well in advance, since processing times can vary.
The rock of the islands shows traces of ancient volcanic activity in its composition, which sets them apart from most other coastal formations in the region. Looking closely at the stone surface, volcanic textures can be seen.
