Go dolphin spotting
The seas that lap the Costa de la Luz are a playground for dolphins, so this is prime spotting territory. For the biggest success rate, join a boat trip charting a course for the Strait of Gibraltar. As you steer along the coast, you can spot common, bottlenose and striped varieties. And if you’re really lucky, you might just see a whale. Pilot and baleen whales have been clocked around these parts.
