Even before you make it to the ocean, you will have got your money's worth with the sights you'll see on Lisbon's waterfront. From ancient monuments to modern-day architectural marvels, the city itself is as spectacular as the nature beyond its borders.

While at sea, you'll run into countless creatures, from sea turtles to sharks and jellyfish. The chance of a dolphin sighting is high, so make sure you keep your eyes peeled on the water as well as the Portuguese coast.
