In the right wintry conditions, an ice bridge forms between the Diomede Islands in the Bering Strait. Theoretically, this is the only place where you can walk from Russia to the United States (and vice versa), however travel between one Diomede to the other is strictly forbidden.
On the West side sits Russia’s Big Diomede with a population of 0. The smaller Little Diomede to the East has a small population of 82 (as of 2021).
