Saba (säˈbə) [key], island (1990 est. pop. 1,100), 5 sq mi (13 sq km), a special municipality of the Netherlands, one of the NW Leeward Islands, West Indies. It was formerly part of the Netherlands Antilles. The rugged island is actually the cone of an extinct volcano rising to c.2,800 ft (850 m). Spiral roads winding up through steep cliffs and lush greenery make Saba a scenic island, but there are no sheltered harbors, and landing is difficult. The chief settlement, called The Bottom, is in the crater of the volcano. The Dutch settled the island in 1632.
