Book in Advance

The good news: Many cruise lines take reservations far ahead of the actual cruise. The bad news: Cabins on Alaska cruises can sell out up to 18 months in advance.

Booking a cruise to Alaska well in advance is the best course of action. Early reservations give you access to a variety of itineraries, dates and cabins before they’re all taken. As an added bonus, cruise lines often give extra perks to those who book early, such as free airfare or onboard credits.

When to Go

Ships don’t sail in the wintertime in Alaska, so the cruising season only lasts from May through September.

The peak season for Alaska cruising is mid-June through late August. Those who wish to avoid crowded ports or a cruise with children and teenagers should book their trip for May or September.

There are seasonal aspects to consider as well. Spring and early summer provide more opportunities to witness animals as they migrate, while mid-June to August offer the best daylight for excursions. To view the mysterious aurora borealis lights, September is your best bet, though late spring may work as well.

What to Pack

Despite the cruise season taking place during the summer, pack for colder weather. Windbreakers, sweaters and other clothing that can be layered are recommended.

Depending on the itinerary you choose, pack clothing for the outdoors. Excursions may involve hiking or canoeing, so bring clothes you don’t mind getting wet or dirty.
