European travelers have long favored walking tours that take them from one lodging to another, known as hut-to-hut hiking. The concept is gathering steam in the U.S. as more tour operators and organizations offer various derivatives. The accommodations on the walking tours range from luxury inns to backcountry huts. "People want to feel like they're getting out of the hubbub. But they don't want to sleep in a tent and eat freeze-dried food," said Brad Niva, owner of Rogue Wilderness Adventures in Oregon.
