It might not sound like your sort of vacation, but there's a hardy group of tourists who head north when the temperature is plunging.
Alaska tourism officials say about a-quarter million visitors come to the state during the winter and 75 percent are making their second trip.
Winter-time attractions include the spectacular Northern Lights, if the weather cooperates.
There's also dogsledding and snowmobiling.
After hours, winter visitors can soak in an outdoor hot tub surrounded by snow.
