A cruise through the Inside Passage gets you glaciers, whales and pretty port towns — but it only shows you half of Alaska. The other half is inland: tundra, grizzlies, Gold Rush towns and Denali, North America's tallest peak at 20,310 feet. A cruisetour bundles both into one trip: roughly a week at sea plus several days on land, with trains, lodges and transfers handled for you. It's usually cheaper than booking the cruise and land portion separately.

The Picks: who suits what

First-timers are well served by Princess, one of Alaska's biggest operators with its own railcars and wilderness lodges. Its Denali Explorer pairs the seven-night Voyage of the Glaciers cruise (Vancouver to Whittier, calling at Skagway, Juneau and Ketchikan, plus Glacier Bay and College Fjord) with two to six nights ashore, including two nights at Denali Wilderness Lodge. Holland America is the pick for Gold Rush history — it's the only line running cruisetours into the Yukon and Dawson City, with the White Pass & Yukon Route Railway and a Klondike tour developed with the History Channel.

Families get the big-ship treatment on Royal Caribbean's Anthem of the Seas: surf simulators, skydiving, 16 restaurants and a glass capsule rising 300 feet above the sea, then ziplining at Icy Strait and a sled-dog kennel visit near Denali on the 10-night Tundra Explorers itinerary. Solo travellers should look at Norwegian Bliss, which has a keycard-only Studio Complex for single occupancy, plus a 14-day Authentic Alaska route with two nights in Homer, the state's halibut-fishing capital.

Food-focused travellers can try Celebrity's 10-day Authentic Tastes of Alaska — smoked salmon in Seward, akutaq (Alaska Native ice cream) at the Anchorage heritage center, brewpubs in Talkeetna — sailing on the refurbished Celebrity Solstice. Azamara's 14-night Denali, Talkeetna, Riverboat & Rail run caps at just 700 guests, so the ship reaches smaller ports like Haines and Valdez, and you can tack on a Rocky Mountaineer extension into the Canadian Rockies. For expedition-style travel, Windstar's new 112-suite Star Seeker carries eight naturalists, kayaks and Zodiacs into spots like Tracy Arm, Wrangell and Kenai Fjords.

Practical stuff

The season is short: May to September. May and June bring fewer crowds, blooming wildflowers and wildlife emerging for summer; July is warmest with near-24-hour daylight; August means salmon runs and bear sightings; September offers autumn colour and your best shot at the northern lights. Book nine to 12 months out — Denali lodges and the popular dome-rail journeys sell out first. Most cruisetours run 10 to 19 days, and summer temperatures sit between the mid-50s and low 70s Fahrenheit, so pack layers for every kind of weather.

Why it matters: if Alaska is on your list, a cruisetour answers the classic regret of cruise-only visitors — seeing the coast but missing Denali and the interior entirely. Pick the line that matches your travel style, book early, and you'll cover glaciers, wildlife and Gold Rush towns in a single holiday.
