Yurt: It's a fun word to say and a fun place to stay. These round structures originated with nomadic tribes of the Central Asian steppes, but they're catching on in the U.S.; this one is located at the Treebones Resort on the California Big Sur coast, where yurts start at $155 per night. Other yurts can be rented in state parks around the country, often as low as $45 a night.

Talk about a room with a view! Fire lookouts like this (as well as more accessible rustic cabins) are a great camping alternative and can be reserved through the U.S. Forest Service (www.recreation.gov) for a minimal nightly fee, often around $25. "Amenities" vary widely: Some may come stocked with cooking pots and dishes; others may not have potable water. If the "pack in, pack out" way of life doesn't deter you or your fellow travelers, this option is for you.



It's not all that unusual to stay in a lighthouse thats been converted into a bed-and-breakfast; staying in a working lighthouse is a rare experience. The Rose Island Lighthouse in Newport, R.I., on the National Register of Historic Places, lets guests stay overnight in the museum bedrooms. Or, you can opt to perform the duties of a lighthouse keeper for a week. Weekly rates range from $700 (winter) to $2,100 in summer high season and its all tax deductible.
