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.

On this 90-minute Private All Access Tour (exclusive to NCL guests), you will have a unique opportunity to explore the 2.5-mile Speedway from a variety of vantage points. Take the rare opportunity to come face-to-face with the track as you visit the well-known start/finish line and 31-degree high banks or ride down pit road to get a close-up view of the pit stalls. This tour provides you with unprecedented access like a visit to the media deadline room, a photo in Gatorade Victory Lane and a look inside the world's first motorsports stadium as you hop onto one of the 40 escalators and are transported into the new front-stretch stadium for a stunning view of the tri-oval and infield.

End the day by standing next to the car of this year’s DAYTONA 500 champion, left in the same condition as the day it conquered the World Center of Racing inside the new Motorsports Hall of Fame of America that is now housed in the DIS Ticket and Tours Building. The Hall of Fame showcases spectacular displays honoring all forms of motorsports: Stock Cars, Sports Cars, Open-Wheel, Motorcycles, Drag Racing, Land Speed Records, Power-boating and Aviation.

After your tour, visit ONEDAYTONA located across the street via raised safety-bridge. ONE DAYTONA will serve as the Daytona Beach area’s epicenter for premier retail, dining and entertainment.

Aquaventure, Atlantis Paradise Island’s Water Park, is a one-of-a-kind 141 acre waterscape. Aquaventure features over twenty million gallons of water, thrilling high-speed water slides like the Mayan Temple and the 7-story Power Tower, a mile long river ride with rolling rapids, a spectacular kids water-play fort, 20 swimming areas, refreshing pools, and access to the most beautiful beaches in the Caribbean!

The old port of Mandraki, where this tour begins, is believed to be the site of the Colossus of Rhodes, one of the Seven Wonders of the Ancient World. Historic sites abound in Rhodes, as you will soon discover after enjoying a panoramic view of the city and Rhodes Bay from atop Monte Smith.

Visit the fully restored 14th-century Grand Masters Palace, which contains beautiful alabaster windows, French and Venetian furniture, and floor mosaics with scenes from Greek mythology. 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.

Your relaxing fun-filled day begins with a short scenic ride to a quaint marina where you’ll board the catamaran. At the marina dock, your friendly crew will greet you and acquaint you with the vessel. Glide along the eastern end of the island before setting sail to the most pristine of the U.S. Virgin Islands. The brisk sail across Pillsbury Sound brings you to a special mooring destination where you can swim on a beautiful St. John beach, snorkel or simply relax under the palms. Enjoy freshly baked breads, cheeses, fruits, and a variety of beverages onboard. Champagne and other beverages are complimentary after swimming and snorkeling. After your relaxing stay at the beach, delight in the tropical breezes as you make the downwind return sail to St. Thomas.

Visit several of Old Town’s most iconic sites, which gained even greater fame after serving as locations for the fictional capital King’s Landing in “Game of Thrones.”

After departing from the pier, you will soon arrive in the oldest section of Dubrovnik, a revered UNESCO World Heritage Site. Fans of the TV series “Game of Thrones,” which is based on George R. R. Martin’s “A Song of Ice and Fire” fantasy novels, will recognize this part of Dubrovnik as King’s Landing, the fictional capital of the Seven Kingdoms.

Your first stop will be imposing Lovrijenac Fortress, located just outside the medieval walls that encircle Old Town. Known as Dubrovnik’s Gibraltar, the 11th-century fortress perches atop a craggy rock overlooking the sea, which represented Blackwater Bay in the books.

Continuing on, you will enter Old Town and make your way to the defensive walls to the south. After climbing the steps, you will walk along the stone battlements, which afford extraordinary views of the sea and the inner city. These walls appeared in numerous scenes in “Game of Thrones”; they were particularly prominent in the Battle of Blackwater Bay.

Later, you will enjoy free time within Old Town, where you may explore other sites that you may recognize from the series. For instance, the Jesuit Staircase was where Cersei Lannister began her Walk of Shame in Season Five, and many of the show’s market scenes were filmed along St. Dominic Street. Following free time, you will return to the pier.

Discover the charms of Granada, the architecturally stunning capital of the Andalusia region, by exploring a magnificent palace, the Royal Chapel and the city’s oldest quarter.

After departing from the pier, you will settle in for scenic drive inland to Granada, a city likely named for the Spanish word for pomegranate, a fruit so abundant it is depicted on Granada’s coat of arms. Or Granada may have derived from its Moorish name, as the city was the Moors’ last stronghold before falling to Spain’s Catholic monarchs in 1492.

Granada features a wealth of extraordinary architecture such as your first stop, the Carlos V Palace within the Alhambra complex. Construction on the palace began in the early 16th century, following a Renaissance ground plan with a circular courtyard within a square building—the only one of its kind in Spain. Amazingly, a monarch has never lived in the palace, nor did it even have a roof until 1957.

Walking a bit farther, you will soon arrive in the labyrinthine streets of the Albayzin quarter (down part of the quarter), the city’s oldest section. UNESCO has deemed it a World Heritage site for its harmonious blend of Moorish and Andalusian architecture.

Nearby, you will find the glorious Royal Chapel, the final resting place of Spanish monarchs such as Queen Isabella and Kind Ferdinand. Be sure to see the chapel’s mausoleum, spectacular altarpieces and ornate grilles before enjoying free time and perhaps lunch on your own in the surrounding historical area.

Afterwards, you will drive back to Malaga.

Enjoy the amazing scenery of Teide National Park and ride a cable car up Mount Teide, the world’s third highest volcano and a sacred site for Tenerife’s aboriginal people.

After departing from the pier, you will drive inland along an immensely picturesque, circuitous route and on into Teide National Park. The largest of the Canary Island national parks, Teide features a colossal stratovolcano that contains Mount Teide, the highest peak on Spanish soil. Its stunning geological formations are so important to understanding how volcanic islands are created that the park has been named a UNESCO World Heritage Site.

The now dormant volcano last erupted in 1798. It also erupted in 1492, supposedly as Christopher Columbus was sailing past on his voyage of discovery. Your approach to Mount Teide will be through a volcanic crater 30 miles in circumference.

The closer you come to Mount Teide, the more surreal and lunar the landscape will appear. The terrain is a jumble of bizarre natural rock formations, petrified lava rivers and endemic vegetation. One of the most spectacular plants is the red bugloss, a species with 6-foot, cone-shaped stems covered in pinkish-purple blossoms.

More phenomenal sights await you while ascending Mount Teide via cable car. From this unique perspective, you will enjoy sweeping views of the volcanic landscape and the ancient crater rimmed with red, brown and yellow walls. Upon reaching the summit, you may explore further during free time before retracing your route back to the pier in Tenerife.

Snorkel the azure waters of Belize's Barrier Reef, the world’s largest living barrier reef. This is a shallow water entry, well suited for beginners and intermediate snorkelers.

Depart from the Harvest Caye Marina on one of our comfortable snorkel vessels for the short scenic ride to a beautiful site along the reef. This location is teeming with multitudes of colorful reef fish, co-habiting among the beautiful hard and soft coral formations, intermingled with sponges, sea fans and delicate sea anemones. Possible sightings of spotted eagle rays and schools of larger fish are quite common, large starfish, queen conchs and sea cucumbers also call this patch of the reef home.

After snorkeling, re-board your boat and enjoy the return trip with complimentary rum or fruit punch while listening to Caribbean rhythmic vibes.

Come experience the world famous, magnificent ruins of the walled city of Tulum, the only Mayan city built right on the blue Caribbean Sea! After a 45-minute ferry to Playa del Carmen, your guide will lead you to an air-conditioned motor coach for a scenic and informative one-hour drive to Tulum.

Once there, your guide will escort you through the ruins giving a complete narration along the way. See the restored temples and some of the mysterious hieroglyphic writings still visible today. Visit the temple of the frescos, famous for the detailed carved figures and original paints. And perched on the edge of the Caribbean and rising high above all of the other ruins is “El Castillo” with its breathtaking view of the aqua-colored water below.

Once back in Playa del Carmen, you may have free time for shopping etc., depending on the ferry schedule. There will be a stop on the way to Tulum to purchase food, refreshments, souvenirs and use of the restroom.

This scenic drive was especially designed for guests who want to take in the island’s highlights with little or no walking. Discover many scenic island sights, such as the National Heroes Square and the Parliament buildings in Bridgetown. Passing Gun Hill, you’ll see the carved stone lion, a landmark dating from 1868. As you drive across the island, you’ll pass through peaceful villages, eventually reaching St. John’s Church, which offers spectacular views of the east and southeast coasts.

After St. John’s Church, continue to the craggy and scenic area on the east coast called Bathsheba, a photographer’s paradise. From here, you’ll have an incredible panoramic view of the hills, gentle slopes and sweeping bays. The stunning boutique hotel, Atlantis is located in the quaint fishing village of Tent Bay. Dramatic views from here create excellent photo opportunities! On the way back to your ship, you’ll pass through Holetown, with its monument commemorating the landing of the first English settlers in 1625.

Venture into the beautiful Thingvellir national park - a UNESCO World Heritage Site only about 30 miles from Reykjavik, and ranking at the top of Iceland’s attractions. This national park offers outstanding sceneries of mountains surrounding a vast lava plain covered in green moss and wild flowers. Head to the Geyser area where you’ll see hissing springs, bubbling pools and other geothermal phenomena. Lunch will be served nearby, amongst these scenic surroundings.

Another highlight of your day is the Gullfoss waterfall. The ‘Golden Waterfall’ is the most famous of the country’s many waterfalls. Here, the river Hvita drops 96 feet in two falls, creating an awesome spectacle. Then, visit waterfall Faxi with its salmon ladder and adjoining traditional sheep round up pen You’ll also stop in the town of Hveragerdi to see an earthquake exhibition. Being located on an old magma chamber, Hveragerdi is notorious not only for its abundance of hot springs, which heat the community’s greenhouse industry, but also for its earthquakes. Lastly, enjoy a scenic drive of the city on your way back to your ship.
