Continue reading to discover the best times to visit Alaska, whether your passion lies in skiing or landing a giant salmon.

Ideal time to explore Alaska via train rides

• Optimal month(s): year-round

For a century, the Alaska Railroad has linked the coastal town of Seward to Fairbanks in Alaska's remote interior, inviting travelers to join the journey along the way.

Although there’s no wrong time to experience one of the Alaska Railroad’s historic journeys, certain times of the year see limited service. From early May to late September, all routes operate daily, but outside this period, only the Aurora Winter Train (operating from Anchorage to Fairbanks) runs on a much-reduced schedule, with some months featuring service only on weekends.

Accommodation options

In the early 1900s, roadhouses were prevalent throughout what is now Alaska. These establishments functioned as a combination inn, restaurant, bar, post office, and more for prospectors heading to the state. Typically located every 10 miles—believed to be the maximum distance someone could carry their belongings in a day—there were once thousands of them. Today, only a few remain, including the Talkeetna Roadhouse, known for its cozy rooms and delicious sourdough pancakes that attract both locals and travelers.

Optimal time to visit Alaska for fishing

• Best month(s): May–September

With its crystal-clear waters and a wealth of fish species, Alaska presents anglers with serious opportunities for memorable “it was this big” stories for years to come. However, the best time to visit this fishing haven hinges on what you aim to catch.

While Alaska is famous for its salmon runs, each of the five salmon species boasts distinct flavors, textures, and sizes, making the ideal time to fish for them contingent on your preferred variety. The two most sought-after salmon species among visitors are usually king salmon (available from May to mid-July) and silver salmon (from late July to early September).

In addition to salmon, other popular catches for anglers include halibut (from May to September), arctic char and grayling (from June to August), and trout (available from May through September).

Accommodation options

In a previous life, Waterfall Resort operated as a salmon cannery, but now guests can stay in renovated staff quarters and enjoy days filled with fishing for salmon, halibut, rockfish, and ling cod, within the limits and luck of the catch.

Optimal time to visit Alaska for skiing

• Best month(s): January–February

With mountain ranges like the Chugach and abundant snowfall, Alaska provides excellent conditions for skiers and snowboarders. Midwinter, particularly January and February, is considered the height of the skiing season, featuring the deepest snowpack and relatively milder temperatures (around low 20 degrees F) compared to previous months. The longer daylight hours—compared to December—allow for more time to enjoy the slopes and breathtaking views.

Accommodation options

For resort-style skiing, visit Alyeska Resort. Located just south of Anchorage, this is Alaska’s only true ski resort, famous for its “steep and deep” terrain and boasting the longest continuous double black diamond ski run in the nation. The 2023–2024 season promises to be exciting for Alyeska as it joins the Ikon pass and its Nordic spa has officially opened.

If you’re after untouched powder stashes, Tordrillo Mountain Lodge is your best option. This remote lodge offers multi-day heli-skiing adventures, where guests are flown into the backcountry by helicopter to access nearly inaccessible terrain.

Optimal time to visit Alaska for the Northern Lights

• Best month(s): September–March

Although the aurora borealis, or Northern Lights, occurs every night in Alaska, it’s not always visible—certain conditions must be met first.

First and foremost, it needs to be dark. Since Alaska experiences the midnight sun for much of summer, mid-September to early April provides the best chances to see the lights. Typically, the Northern Lights are most vibrant and powerful in the weeks leading up to and just after the equinoxes in late September and mid-March. This is due to the Earth's tilt, which allows electrically charged solar particles to better reach the planet's polar regions.

Accommodation options

Fairbanks, Alaska, is positioned directly beneath the Auroral Oval, a region that encompasses the northernmost areas where most auroral activity occurs, allowing it to experience the lights an average of 240 nights each year. Borealis Basecamp, a luxury glamping resort featuring geodesic igloos with skylights, is located about 30 miles from Fairbanks, away from its light pollution, making it a prime spot for chasing the aurora.

Optimal time to visit Alaska for cruising

• Best month(s): April–October

With Alaska’s fjords, rich wildlife, and 6,640 miles of coastline, it’s no surprise that cruising is one of the most favored ways for visitors to discover this stunning state.

The best time to cruise Alaska is during the summer months, from June to August (though the season begins in late April and runs through early October). This timeframe boasts some of the finest weather conditions, with temperatures typically ranging from the 50s to 70s Fahrenheit. It’s also when wildlife and port towns emerge from hibernation, and whales return to their summer feeding areas.

Accommodation options

Each summer, numerous ships navigate Alaska’s coastal waters, ranging from intimate 12-person expedition vessels to massive ships carrying thousands of passengers. Consider Alaska Dream Cruise’s Remote Alaska Adventure (a 10-day voyage with the only Indigenous-owned cruise line in the country through the Inside Passage), Hurtigruten Expeditions’ Inside Passage, Bears, and Aleutian Islands (an 18-day journey starting in Vancouver and concluding in Nome), or Lindblad’s Exploring Alaska’s Coastal Wilderness (an 8-day trip between Juneau and Sitka)—just to name a few.

Optimal time to visit Alaska for wildlife watching

• Best month(s): April–October

Alaska provides incredible wildlife encounters year-round, but for viewing whales and bears, the summer months are ideal. This is when bears emerge from hibernation and whales breed in warmer waters, unlike winter when they are less visible.

Many tour operators offering excursions to view humpbacks, orcas, and minkes in places like Juneau, Seward, and Homer kick off their season in April and wrap up in October.

While bears—including black, brown, and polar—can be found throughout Alaska, a visit to Katmai National Park or Lake Clark National Park is highly recommended if you want to maximize your chances of seeing them; these parks boast some of the highest densities of coastal brown bears in the world.

Accommodation options

For a base camp that offers both whale-watching and bear-viewing opportunities, consider Tutka Bay Lodge, situated near Homer. Guests often spot whales from the lodge, which is nestled in a secluded cove. Tutka Bay can also assist in arranging off-site half-day excursions for wildlife viewing.

Optimal time to visit Alaska for the Iditarod

• Best month(s): March

Every year, approximately 50 mushers set off from downtown Anchorage for a grueling nearly 1,000-mile race to Nome, a small community on the Bering Sea, as part of the Iditarod Trail Sled Dog Race. Often called “The Last Great Race,” this long-distance dog sled competition traverses some of the most challenging terrains and extreme weather conditions on Earth.

For over 50 years, mushers and their dog teams have begun their journey from Anchorage amid the excitement of the ceremonial start, held on the first Saturday of March. After departing from downtown, the teams travel to Willow, about 70 miles away, where the race officially commences the next day. About eight days later, the fastest team reaches Nome.

Accommodation options

While you can witness the race's conclusion in Nome and track its progress from various communities along the route, options for accommodation in rural Alaska are limited. Most visitors prefer to stay overnight in Anchorage and participate in the ceremonial and official start festivities. Anchorage also hosts the Fur Rendezvous, a two-week festival leading up to the Iditarod. A great lodging choice near the festivities is Hotel Captain Cook, touted as Anchorage's only luxury hotel, which has welcomed numerous celebrities and dignitaries, including Sir Elton John and President Barack Obama.
