11 Night New Zealand Cruise

Sydney, capital of New South Wales and one of Australia's largest cities, is best known for its harbourfront Sydney Opera House, with a distinctive sail-like design. Massive Darling Harbour and the smaller Circular Quay port are hubs of waterside life, with the arched Harbour Bridge and esteemed Royal Botanic Garden nearby. Sydney Tower’s outdoor platform, the Skywalk, offers 360-degree views of the city and suburbs.

Mountains and waterfalls abound in South Island's Milford Sound, one of New Zealand's top attractions and a site of otherworldly beauty. Called the eighth wonder of the world by Rudyard Kipling, the sound (technically a fjord) is part of Fiordland National Park and the Te Wahipounamu World Heritage Site. Take in the surrounding water on nature on your Milford Sound cruise, passing by green cliffsides and plummeting waterfalls like Lady Elizabeth Bowen Falls. Along the way, take in the famous Milford Track: Suspension bridges, boardwalks and mountain passes take you past stunning vistas of emerald green mountains and valleys, as well as Sutherland Falls, the tallest waterfall in New Zealand.

Situated in Fiordland National Park, Doubtful Sound is the deepest and second-largest fjord in New Zealand. It was named by Captain Cook, the first European here, because he was doubtful that he would be able to sail his ship, the Endeavor, back out of the sound due to the westerly winds. Look for the area's towering waterfalls: See 619-meter Browne Falls in Hall Arm and 220-meter Helena Falls at Deep Cove. Try to spot dolphins, penguins and fur seals in the waters and shoreline below with your Doubtful Sound cruise.

Dusky Sound lies among the grand fjords of Fiordland National Park in the southwest part of New Zealand's South Island. Named by Captain Cook when he sailed by at dusk on his first voyage in 1770, this spot holds one of the area's largest fjords, at almost 25 miles long. During the rainy season, you can spot hundreds of waterfalls splashing down from the verdant green hills into the dark deep waters. During your Dusky Sound cruise, keep an eye out for sunbathing seals in repose on Seal Rock. Look out for Astronomer's Point, a former observatory dating back to 1773 that overlooks the dramatic fjord.

On the southeast coast of New Zealand's South Island, on the Otago Peninsula, you'll find Dunedin. The city basks in its Scottish heritage — its name is actually the Gaelic word for Edinburgh. No Scottish city would be complete without a castle: Explore Dunedin's Larnach Castle and Gardens, a Gothic Revival mansion surrounded by impeccably manicured rows of rhododendrons, azaleas and Scottish heathers. Then, check out Baldwin Street, the world's steepest residential street. Cruise to Dunedin and explore St. Paul's Cathedral in the city's center, the Octagon. Or head to Taiaroa Head at the end of the Otago Peninsula, where unique wildlife abounds: Spot the rare yellow-eyed penguin, New Zealand fur seals and royal albatross.

Named after a college at the University of Oxford, England, Christchurch has a reputation for being a conservative, "British" city. This may be true on the surface, but a bit of poking around this largest city of the South Island, population 360,000, will reveal a vibrant arts culture and adventurous spirit that's 100% "Kiwi."

It's hobbit enthusiast's dream come true in Tauranga. This town on the Bay of Plenty, perched on New Zealand's North Island, is just a short trek from the rolling hills of Waikato — this is where you'll find Hobbiton, the location that served as the Shire in the uber-popular "Lord of the Rings" movies. But the fantastic findings of Tauranga don't end there. Cruise to Tauranga and hike to the summit of nearby Mount Maunganui, an extinct volcano that offers panoramic views of the city and the Pacific Ocean below. Or take the one-hour drive to Rotorua, a geothermal fairyland where you can soak in the rejuvenating waters of the natural hot springs.

Look up — the Bay of Islands is said to have the world's second bluest sky after Rio de Janeiro. Located on the northwestern coast of New Zealand's North Island, the sea here is also a beautiful shade of turquoise, dotted with 144 subtropical islands of the area. Cruise to Bay of Islands and check out Urupukapuka Island, where you can hike through Maori village sites or relax on the white-sand beach. Visit the Waitangi Treaty Grounds — this is the site where the treaty that made New Zealand into its own nation was signed. Or head out on a dolphin spotting cruise to see the population of bottlenose dolphins that call these waters home.
