Ski Portillo, Chile 
 Up in the Chilean Andes sits Ski Portillo, one of South America's most historic ski resorts, which is also home to a rather special pool.
 
 
 You'll be glad to know it's heated, thanks to the mountains' geothermal energy, making it perfect to gently relax weary limbs after a day on the slopes. Watching the sunset over the Laguna del Inca lake below caps off a distinctive swim.
 
 
 The pool is free to hotel guests, while ski season runs from June through October. A week's accommodation in a valley view room with lift passes and four meals daily runs from $3,750.
