Saba, an island in the Lesser Antilles, is a part of the Netherlands. Though English is widely spoken, Dutch is also an official language here. This is arguably the most naturally beautiful European territory on our list. Unlike most Caribbean islands, Saba was not formed on a reef, so it has steep sea cliffs and lush interior jungles instead of wide, sandy beaches.
On Saba, diving and trekking replace the usual Caribbean tourist pastimes of sunning and swimming. Some of the buildings here have a Dutch feel, but the tropical landscapes are what really define Saba and make it such an unusual island.
