Whether you’re spotting whales and bears from the comfort of your stateroom balcony or kayaking through iceberg-filled bays, an Alaska cruise is one of the best ways to experience the epic landscapes of the Last Frontier. Alaska’s cruise season typically runs from May to September, and the most popular itineraries, cabins, and shore excursions can sell out early—so it’s smart to plan at least six to eight months in advance (and often earlier for peak weeks).

On an Alaska cruise, you can hang out with sled dogs, chat with Iditarod-winning mushers, watch lumberjack demonstrations, and enjoy experiences you simply won’t find anywhere else.

Royal Caribbean offers the North Star observation capsule. Available on Ovation of the Seas, Quantum of the Seas, and Anthem of the Seas, the attraction lifts guests more than 300 feet above sea level for 360-degree views. It’s a truly unforgettable way to take in Alaska’s scenery from a whole new perspective.

Why an Alaskan Cruise in May?

• Lower Costs & Smaller Crowds: May is part of the “shoulder season,” which often means better pricing on cruises and shore excursions. Popular ports like Juneau, Ketchikan, and Skagway are typically less crowded than in July or August.
• Drier Weather and Scenery: May is often one of the driest months of the Alaska cruise season. Mountains are still heavily snow-capped for dramatic, wintery photo ops, while temperatures begin to warm—average highs are usually in the mid-50s
  .
• Wildlife and Nature: Late May can be ideal for spotting baby moose and seeing bears out and feeding on fresh vegetation. It’s also the beginning of the whale migration season—prime time for wildlife watching.
• Longer Daylight Hours: By mid-May, Southeast Alaska can see around 17 hours of daylight, giving you more time to explore ports, enjoy scenic cruising, and take in the views.
• Lower Bug Population: Cruising in May helps you avoid peak mosquito season, which tends to ramp up later in the summer.
