Not far from the entrance to Aconcagua Provincial Park, the Puente del Inca, or Inca Bridge, still stands much as it did thousands of years ago: a natural arching rock formation extending over the Vacas River. Here, near the turn of the 20th century, a luxury hotel was built on the site of the bridge's natural hot springs, which the Incas long before believed to have healing properties. Though all but the hotel's foundations and a neighboring church were destroyed by an avalanche in 1965, its ruins, along with the fascinating and picturesque bridge itself, are still a unique cultural site to take in while en route to the Western Hemisphere's highest mountain. When ventured to on their own, however, it's worth bearing in mind that they run the risk of seeming a bit anticlimactic for the investment. Just be sure to plan your visit accordingly.
