1/15 Bubble Tree, France
This unique hotel allows guests to literally live in their very own bubble. It makes an ideal place to stay for those who want to enjoy star gazing before falling asleep, or just want to feel as if they're at one with nature. French designers created these otherworldly spheres in various scenic regions across France, including upon the grounds of a 16th century castle, Chateau de la Foret.
If you're concerned about privacy, the bubbles can be covered up at night. Each room, or "bubble," comes with a complimentary telescope for budding stargazers to enjoy the night sky as well as a chart to log discoveries.
