Have you ever dreamed of sleeping underground? Or in a tree? The bed and breakfasts listed here give you those opportunities -- as well as the chance to sleep underwater, in a monastery, or in a jailhouse. These are some of the most unique getaways available to travelers anywhere.
1. Underground Bed and Breakfasts
Coober Pedy, located in the far northern outback of South Australia, is known as the opal capital of the world. One of Coober Pedy's most distinctive features is the fact that about half of the 3,000-person population lives in underground homes. If spending some time underground appeals to you, these bed and breakfasts may be just the getaway you're looking for.2. Treehouse Bed and Breakfasts

Treehouses are the realm of children, right? Putting aside the Swiss Family Robinson, no adult would stay in a treehouse. Or would they? It turns out that treehouse accommodations, perfectly suitable for adults, are available in locations around the globe, from Alaska to Hawaii, from Turkey to Papua New Guinea.

Sleeping underwater sounds like a dream. But modern architects have made this dream a reality, with several "underwater hotels" currently in the planning stages and at least one currently accepting guests.
