The best time to go to Alaska is from mid-May to mid-September. During this period, the weather is milder, wildlife is abundant, and daylight lasts up to 20 hours, perfect for outdoor adventures. June and July offer peak conditions for hiking, fishing, and glacier tours. For fewer crowds and stunning fall colors, late August to early September is ideal. Winter, from November to March, is great for viewing the Northern Lights but comes with colder temperatures.
