Alaska cruises usually comprise a seven-day itinerary along the Inside Passage and visit Glacier Bay National Park or Hubbard Glacier, stopping at four ports along the way. Most cruise lines also offer a variety of extended cruise-tour package options which take passengers deeper into Alaska via train and include land stays at lodges and sightseeing in Denali National Park - making their trip to Alaska even more comprehensive.
For climate and sunlight purposes, cruises to Alaska sail strictly during the summer months, from early May to mid-September. June, July and August can be classified as peak season when average daily high temperatures can reach 75 degrees Fahrenheit, so those looking for the best value should check sailing dates in May and September when temperatures hover around 50 degrees.
A variety of cruise ships sail to Alaska, including luxury vessels and midsize ships - most of which offer expanded kids programs for family vacationers. While the majority of ships sail from Vancouver, BC, Seattle is increasingly becoming a popular summer homeport for many lines. Both embarkation/disembarkation points allow ships to visit the most popular ports on an Alaska cruise, including Juneau, Ketchikan and Skagway.
