Deciding the best time to take an Alaskan cruise depends on your interests and preferences. The peak season, from May to September, offers the warmest temperatures and the most daylight hours, making it ideal for wildlife viewing and outdoor activities. However, it is also the busiest and most expensive time to cruise.
If you're looking for a more intimate and budget-friendly experience, consider cruising during the shoulder seasons, April-May and September-October. The weather is still generally mild, and there are fewer crowds, but you may have fewer options for excursions and activities.
