The Balearia ferry company has been conducting docking tests this weekend in Motril and Melilla with a view to introducing a new ferry service between the two cities from this May. It’s understood the company would adapt one of the existing buildings at Motril Port for use as a passenger terminal should they decide to go ahead, and would build its own facilities at a later stage.

La Opinión de Granada said Balearia would operate two types of ferry on the Motril-Melilla route: the standard ferry, which would complete the trip in just under four hours, and a fast ferry, with capacity for 870 people and 200 cars, which would arrive in Melilla in a little over two and a half hours.
