Let's play a game and pretend you live in, say, Salina, Kansas, close to the geographic center of the United States. From Salina, Southeast Alaska is about 2,100 miles away, the Champs-Élysées is 4,650 miles, and the Great Pyramid of Giza is 6,700 miles. Point is, you're a long, long way from a lot of things, so if you take the time to go there, you probably want to stay a while and see everything you can. That's the basic idea behind cruisetours -- that and the fact that cruise ships aren't really good at going inland, where a lot of the world is located.
Cruisetours are no mystery in and of themselves: They're a cruise plus a tour, in either order. Mystery seeps in, though, when you start looking at all the cruisetour options -- dozens and dozens of them, listed one after another on the cruise lines' websites as if you really have the time and energy to sort through them all.
Here, then, is a primer, a short reference guide to both the most popular and most distinctive cruisetours in some of the world's most popular sailing regions, along with the most prominent lines that offer them. In addition to these tours, many lines also offer occasional pre- or post-cruise trips to other destinations, from India's Taj Mahal to the Great Pyramids of Giza.

Denali/Anchorage/Fairbanks
Lines: Princess, Holland America, Royal Caribbean, Celebrity, NCLThe most popular cruisetour route typically consists of a 7-night Inside Passage cruise plus a 3- to 5-night excursion inland to giant Denali National Park, home to 20,320-foot Mt. McKinley, the tallest mountain in North America. Princess has the most mojo on this route, operating its own beautiful wilderness lodges and an exclusive rail link right from the pier at Whittier, which speeds your trip to the Alaskan Interior. Travelers spend a couple days at the park, gandering at scenery and trying to spot bear, moose, and other wildlife. Tours that stop in Fairbanks offer optional excursions like paddle-wheel day cruises on the Chena and Tanana rivers, jet-boat rides, and excursions to decommissioned gold mines and dredges. For families, Princess offers a version of this tour that ramps up the novelty and adrenaline to keep junior happy. For budget-conscious travelers, there's an a la carte version that provides transportation and lodging but leaves you to explore on your own at the destinations.

The Klondike
Line: Holland AmericaHAL's big niche in the Alaska cruisetour market is its 7- to 10-night tours of Canada's Yukon Territory. Travelers transit inland via Skagway's White Pass & Yukon Route Railroad, then go on to destinations like Whitehorse, the territorial capital; Dawson City, a picture-perfect gold rush town; and the Yukon River, on which you take a 102-mile catamaran cruise between Dawson and the Alaskan gold rush town of Eagle. From here, you continue on by bus to Fairbanks, then by domed rail car to Denali and Anchorage. The tour can be taken in either direction.

Europe
One could consider Europe the spiritual home of the cruisetour, the place where well-to-do Americans in the late 19th and early 20th centuries took their summer Grand Tours after sailing transatlantic on one of the great steamships. Today's European cruisetours are the antithesis of those offered in Alaska, concentrating less on the continent's bucolic countryside and more on its great cities.Photo Caption: Astronomical Clock detail in Staromestske Square, Prague.

Australia & New Zealand
Australia and New Zealand are almost the definition of "faraway places that I should see a lot of while I'm there." Cruises to this neck of the world visit cities like Sydney and Melbourne (New South Wales), Hobart (Tasmania), and Dunedin, Christchurch, Tauranga, and Auckland (New Zealand), while cruisetours tend to concentrate on one or another of the neighboring countries.Photo Caption: The Twelve Apostles along the Great Ocean Road outside of Melbourne, Australia.

The Middle East
Lest we forget, the Middle East was the Cradle of Civilization, where agriculture, architecture, and trade were first conceived and nurtured, and where art, music, and science flourished while Europeans were mired in the deep funk of the Dark Ages. Today, cruises in the region take in the Ottoman grandeur of Istanbul, Turkey (which straddles the border between Europe and the Middle East); the ancient wonders of Egypt; the historical and religious sites of Israel; and the modern wonders of Dubai and the United Arab Emirates.Photo Caption: The Pyramids of Giza outside Cairo.

Buenos Aires & Iguazu Falls
Lines: Celebrity, PrincessThis 4-night tour can be done from either Buenos Aires, the capital of Argentina, or Rio de Janeiro, Brazil's vibrant oceanside metropolis. Besides those cities' attractions -- the bronzed bodies and beaches of Rio, the neo-European vibe of Buenos Aires, "the Paris of South America" -- the main destination is Iguazu Falls, taller and about twice as wide as Niagara, with cascades spread in a horseshoe over some two miles of the Iguazu River.
