Behold the natural attractions of Cephalonia, including those beneath the surface, such as the Drogarati Cave and subterranean Melissani Lake.

Departing from the pier, you'll drive toward the eastern shore of Cephalonia, the largest Ionian island. Arriving at the Drogarati Cave, you'll descend a flight of stairs into a large cavern which is lighted for dramatic effect. Stalactites hang from the ceiling like jagged curtains, and ancient stalagmites reach up from the rocky floor. The colors are predominately red, orange, yellow and white, from the iron content in the rock and the layers of chalk and limestone.

Although estimated to be 100 million years old, the cave wasn't discovered until about 300 years ago when a violent earthquake opened an entrance. Inside the cave's Chamber of Exaltation, the acoustics are considered near perfect, and concert events are often held in its voluminous interior. Even the famed opera soprano, Maria Callas, sang here.

Continuing on, you will travel in a northerly direction, passing the town of Sami en route to the renowned Melissani Lake. This underground phenomenon looks absolutely magical in the shafts of light that come from 100 feet above, where parts of the ceiling collapsed decades ago. You'll enter the lake by small boat, paddled in so it hardly disturbs the surface of the water, which is a brackish mix of saltwater from the Ionian Sea and freshwater that originated back in Argostoli and then flowed across the island. The stalactites hanging from the ceiling here are estimated to be at least 20,000 years old.

Afterwards, you'll return to Argostoli via a picturesque coastal route that offers spectacular views across the strait to the island of Ithaca, and further along, Myrtos and its dramatic, sheer white cliffs.

Swim in the crystal-clear waters off Grand Bahama with a passel of cute, friendly pigs and then spend time shopping at the largest open-air marketplace in the Bahamas.

After departing from the pier, you will enjoy a scenic drive along the western tip of Grand Bahama Island. Along the way to Deadman’s Reef at Crystal Beach, you will hear about the wild pigs that inhabit this part of the island. It’s not known exactly why or when pigs were introduced to Grand Bahama, but it will become obvious that their descendants have thrived.

Once you wade into the shallow waters, you can expect the pigs to follow, knowing that food awaits. The guide will show you how to feed the pigs and the best ways to interact with them while swimming. The pigs couldn’t be friendlier, cuter or more enthusiastic about the attention. You might even learn their names, as many of the pigs are regulars.

Following this unusual experience, you will enjoy free time in Port Lucaya Marketplace, the largest open-air shopping and dining venue in the Bahamas. The marketplace has dozens of duty-free shops, two straw markets, two craft centers and a variety of restaurants.

You might shop for exquisite jewelry, designer fashions and fine leather goods. There are several art galleries well worth browsing for local paintings and watercolors. The marketplace also offers all sorts of dining options and cuisines.

It served as a fortress in times of war, and a residence for the Grand Master and a meeting place for senior knights during times of peace. As you continue down the Avenue of the Knights, where the knights lived, the cobblestoned street seems to exude a noble and somewhat forbidden aura, as its lofty buildings stretch in an unbroken wall of honey-colored stone, punctuated by huge doorways and arched windows. At the conclusion of this tour, you can either return to ship, or remain in the old town to explore further on your own.
