Experience the extraordinary beauty of Peru's Cordillera Blanca on this high-altitude trek for experienced hikers. Explore the highest tropical mountain range in the world, with 27 peaks over 19,000 feet, linked by isolated valleys. Hike through a glacial wilderness of translucent turquoise lakes, hidden waterfalls, and striking pinnacles, and keep an eye out for vicunas and soaring condors. Drink in vistas of sharply ridged peaks, including the remarkable "perfect" pyramid of Alpamayo. Challenging? Yes, but a fantastic, bucket-list triumph for those who choose to undertake it.
