Algarve’s coastline is one of Portugal’s most stunning features—dramatic cliffs, golden beaches, and hidden sea caves. But what really makes Algarve special for travelers is its abundant marine life, especially dolphins. That’s why dolphin watching tours here are so popular. We particularly like tours that combine wildlife encounters with visits to iconic caves like Benagil, or those led by marine biologists who share fascinating insights into these intelligent creatures. For example, the Lagos dolphin tour with marine biologists (see details) offers a chance to learn as you watch, adding an educational twist to the experience.
While some tours focus solely on dolphin spotting, others include exploring caves or combining water activities like snorkeling and slides.
