Castellfollit de la Roca, Spain
Castellfollit de la Roca is a village in Catalonia, Spain, built at the intersection of two rivers on top of a 160-foot-tall basalt cliff that was formed as the consequence of the overlaying of two lava flows. The thousand-year-old settlement is approximately one kilometer long and is home to little under 1,000 inhabitants. There’s a short street that runs in between the houses in case you need to get anywhere. Just picture having a backyard with a cliff drop-off.

Phoenix House, Hawaii
You’re in luck since the Phoenix House is listed on Airbnb if you’ve ever wanted to sleep next to an active Hawaiian volcano! On Hawaii’s Big Island, The Phoenix House lies just outside Kilauea’s danger zone, which means that during an eruption, lava flows quite nearby. Additionally, Kilauea is one of the most active volcanoes right now, so if you decide to go on vacation there, you’re almost certainly going to see some activity!
