Alto Velo Island | The least explored place in the Dominican Republic

Tucked in the southwestern most corner of the Dominican Republic, bordering Haiti, Alto Velo Island is as remote as it gets.
It is located about 40 nmi (74 km) south of Pedernales, it's the southernmost point of the Dominican Republic. The United States claimed the island, which had some strategic significance in 1860 under the Guano Islands Act; it still has never renounced the claim. This claim, however, was mostly ignored, and the island has stayed under Dominican administration since independence.
