The northernmost part of the land border between Guyana and Venezuela runs through the island.
The vast majority of the island is Venezuelan territory (610 square kilometers).
The Island was claimed by British Guiana but mostly ceded to Venezuela, following the Arbitral Award of 1899.
Corocoro Island contains the northernmost point of the disputed border with Guyana, an area referred to instead as Guayana Esequiba by Venezuela.
