Accord­ing to the Natu­ra Vive alpine resort, the next best thing to sleep­ing in a condor’s nest is sleep­ing in one of its three trans­par­ent cap­sules that hang from a moun­tain­side. Made out of aero­­space-grade alu­minum and weath­­er-resis­­tant poly­car­bon­ate, each suite comes with four beds, a din­ing area and, some­how, a pri­vate bath­room. Get­ting there, mean­while, requires guests to scale a via fer­ra­ta course or brave a series of zip lines.
