This cruise sails only from May to August as it’s the best time to enjoy Alaska’s natural beauty.
Visit Alaska anytime between mid-May to mid-September when the days are long and the nature is in full bloom.
Alaska Summer tours operate between mid-May to mid-September, those into Denali (mid-June to end of August). Peak season is mid-June to mid-August. The month of May is dry whereas Alaska's summers are slightly rainier than the rest of the U.S.
The longest day of the year is June 21, with 19 hours of daylight in Anchorage, 22 in Fairbanks, and 18 in Southeast. But from early May through September, days are considerably longer.
Alaskan beauty and summer daylight from mid-May to mid-September are so different from the lower latitudes that we think you'll experience a visit anytime during this period to be magical.
