The magnificent Black Sea region is dotted with cities and sites spanning the course of recorded history, from Trabzon in Turkey and Varna in Bulgaria to the scenes of relatively recent history in Ukraine. In addition to its splendid history and culture, the Black Sea region enjoys a subtropical climate equal to that of the Mediterranean. Embarking in Istanbul, one of the great cities of world history and the pivot point between Western and Eastern civilizations, you will explore the seldom-visited northern coast of Turkey with Ottoman mosques, Byzantine churches, and soaring citadels.
