“Cabotage” came into English in the early 19th century from the French “caboter,” meaning “to sail along the coast.” The original context applied to maritime law and trade — it refers to the right of foreign vessels or aircraft to trade or transport passengers along a nation’s coast or between domestic locations. For example, a foreign cruise ship traveling through United States waters must have cabotage. In a more casual sense, you could use “cabotage” to refer to a vacation that takes you to multiple stops along the coast.
