Hut to Hut camping is very popular in Europe. The US has some of those camp sites but I don't know the location. Outside magazine mentioned about it once.

The hut is located in remote places. Hikers or skiers must hike a few miles from parking lot to the hut. The Hut looks like a Mongolian circular tent. It has wood fire place for cooking and keeping warmth. I don't know about the food availability at those huts. I assume hikers must carry their own food there.
