We have an island in our local River Aar in Switzerland. I was up on the local mountain last week and took a few photos of the river from the top. You can see the island at the curve of the river. The island does not have a name, it does not need one, because it is the only island in our stretch of the river. It is farming land and the only inhabitants on the island is the farmer and his family with his herd of cows. You can visit the island, he picks you up with his boat and when you have arrived on the island you can take a walk or go for a swim in the river. Even the cows go for trips on the boat if necessary.
