Torres del Paine Circuit (hiking), Chile
This 52-mile trail loops through a section of southern Patagonian wilderness that contains some of the most otherworldly scenery on the planet. Giant blue glaciers and craggy mountain peaks are in abundance here, but the most spectacular formations in this national park are the namesake paines—10,000-foot pillars of granite that spiral up from the glacial-carved valley. The challenging hiking circuit also traverses past green lagoons and expansive ice fields—and if the landscape itself weren't enough, eagle-eyed hikers can spot exotic wildlife (llama-like guanacos, ostrich-esque rheas) roaming the grassy pampas.
Book a Trip: Cascada Expediciones offers a five-day, four-night highlights trek; most nights, hikers stay in geodesic eco-domes equipped with sheepskin throws and windowed ceilings for midnight star-gazing (ecocamp.travel, from $1,313).
