The largest islands of the group are Aghiyuk Island and Chowiet Island. The island group has a total land area of 30.178 kmÂ² (11.652 sq mi) and are uninhabited.
They are part of the Alaska Peninsula unit of the Alaska Maritime National Wildlife Refuge and are an ideal location to visit by lovers of Arctic flora and fauna.
The Alaska Cruise season begins in May and ends in September. Although July and August are the warmest months to experience these incredible sites, autumn and spring are the most fun, the most beautiful and the savings are the best. Be prepared for one season colder than the time you are traveling from your departure point. This is especially important for those who travel early and late in the season. The average temperature range is from overnight lows of 4c to daytime temperatures of 17c.
