The fantastic ice range of the Cordillera Huayhuash is renowned for knife-edged 20,000-foot peaks that attract mountaineers from around the world. Seven of Peru's highest peaks rise from this dramatic massif, whose awesome beauty can be seen in the gripping adventure film Touching the Void. Our challenging 14-day trek crosses seven high passes as we circle the entire range, with nearly continuous panoramas of towering Andean giants, including Yerupaja (21,759'), second highest mountain in Peru. Our adventure culminates in an optional climb of Diablo Mudo (17,235'), a non-technical snow peak with panoramic views across the entire Huayhuash. Sunny blue skies, mild daytime temperatures, and a profusion of edelweiss and purple lupine make these mountains an alpine paradise.
