2. Torres del Paine — Chile
Length: 62 miles (100 km), eight days
Difficulty: Moderate to strenuous
When to go: November–April
The Torres del Paine (aka “the towers”) refers to the twisting granite monoliths that reach 10,000 feet into the sky and around which this circuit loops. These towers are just part of the surreal landscape this Patagonian trail offers, alongside vast blue glaciers, jagged cliffs, subpolar forests, wildflower fields, and exotic wildlife including condors, guanacos, and sometimes even pumas. Huts are available, but usually crowded (especially during summer months, when the sun sets at 10 p.m.), and camping is generally considered the better option.
