Among Alaska's hundreds of public cabins, seven of the most secluded are in the Kodiak National Wildlife Refuge, 1.9 million acres of rainforest, tundra, and wetlands spread over four islands in the northwestern corner of the Gulf of Alaska. Expect whales, Kodiak bears, eaglesand competition for reservations at the Uganik Lake Cabin, which looks out at mountains sliding into the water ($45; apply by lottery at kodiak.fws.gov). From Anchorage, fly Alaska Air to Kodiak, and arrange for a floatplane with local Kingfisher Aviation ($430 for four; kingfisheraviation.com). Plan to stay a full week, and don't forget the fishing rod: Dolly Varden run gangbusters between April and November.
