Gather the family and board a ferry boat for a two-hour sail off the coast of Andalusia, looking out for dolphins frolicking in the waves as well as admiring the unique skyline of the Costa del Sol. You’ll be sailing in the Alborán Sea, a transition zone between the Mediterranean Sea and Atlantic Ocean. This body of water is home of the largest population of bottlenose dolphins in the western Mediterranean — chances are good you’ll spot a few. Weather permitting, you may have the chance to go for a swim. And if the weather is clear, you may be able to see Morocco on the horizon.
