Summer is the best time to travel this far north - not just for the warmth and the continuous daylight, but also for the vitality summer brings to all things Alaskan. The winters aren't as bad as you'd think, except for the darkness. Late spring and early fall can be pleasant too. Check the weather forecast for Anchorage shortly before leaving. Party 'till the sun never goes down.
Anchorage is so far north the sun never sets during summer solstice.
Watch for whales if you ride down the scenic Coastal Trail. Alaskans joke that their state begins just north of Anchorage city limits. Anchorage is everything Alaska is not - urban, commercial and busy. Snap some pix of bear, moose, fox, seals and musk oxen at the Alaska Zoo. Learn about Alaskan indigenous culture and history at the Anchorage Historical and Fine Arts Museum.
