Cusco, Peru

Ancient Incan stonework, misty mountain peaks, and vibrant indigenous markets blend in this high-altitude heritage capital.

You know that friend who insists every trip needs a "deeper meaning"? Cusco shuts them up while delivering an actual adventure. At 11,150 feet, this former Incan capital hits different—literally. The altitude gives everything a light, dizzy edge while you're wandering past 500-year-old stonework that somehow fits together without mortar. Your group will split between history nerds geeking out over temple foundations and everyone else just trying to figure out how ancient engineers pulled this off. The best things to do in Cusco span from hiking Sacred Valley ruins to arguing over ceviche spots in San Blas. It's one of those rare cities where a group trip actually works for different energy levels: some of you can tackle Rainbow Mountain at dawn while others sleep off last night's pisco sours, then everyone meets for late lunch. Plus, it's the jumping-off point for Machu Picchu, so you're knocking out a bucket-list item without making it the whole trip. Fly into Alejandro Velasco Astete…
